Anatomical terminology

The face is the front of an animal's head that features the eyes, nose and mouth, and through which animals express many of their emotions. [1] [2] The face is crucial for human identity, and damage such as scarring or developmental deformities may affect the psyche adversely. [1]

Contents

Structure

The front of the human head is called the face. It includes several distinct areas, [3] of which the main features are:

Facial appearance is vital for human recognition and communication. Facial muscles in humans allow expression of emotions.[ citation needed ]

The face is itself a highly sensitive region of the human body and its expression may change when the brain is stimulated by any of the many human senses, such as touch, temperature, smell, taste, hearing, movement, hunger, or visual stimuli. [4]

Variability

The face is the feature which best distinguishes a person. Specialized regions of the human brain, such as the fusiform face area (FFA), enable facial recognition; when these are damaged, it may be impossible to recognize faces even of intimate family members. The pattern of specific organs, such as the eyes, or of parts of them, is used in biometric identification to uniquely identify individuals.

Skeletal anatomy of the face

The shape of the face is influenced by the bone-structure of the skull, and each face is unique through the anatomical variation present in the bones of the viscerocranium (and neurocranium). [1] The bones involved in shaping the face are mainly the maxilla, mandible, nasal bone and zygomatic bone. Also important are various soft tissues, such as fat, hair and skin (of which color may vary). [1]

The face changes over time, and features common in children or babies, such as prominent buccal fat-pads disappear over time, their role in the infant being to stabilize the cheeks during suckling. While the buccal fat-pads often diminish in size, the prominence of bones increase with age as they grow and develop. [1]

Facial shape – such as facial symmetry – is an important determinant of beauty.

Other characteristics

Visible variable features of the face other than shapes and proportions include color (paleness, sun tan and genetic default pigmentation), hair (length, color, loss, graying), wrinkles, [5] [6] facial hair (e.g. beards), skin sagging, [6] discolorations [7] (dark spots, [6] freckles and eye circles [6] ), pore-variabilities, [8] skin blemishes (pimples, scars, burn marks). Many of these features can also vary over time due to aging, [6] [5] [7] skin care, nutrition, [9] [10] [11] [12] [13] [14] the exposome [15] (such as harmful substances of the general environment, [11] [15] workplace and cosmetics), psychological factors, [11] and behavior (such as smoking, [15] sleep, [11] physical activity and sun damage [5] [7] [11] ).

Mechanisms underlying these include changes related to peptides (notably collagen), [7] [11] inflammation, [11] [13] production of various proteins (notably elastin and other ECM proteins), [13] the structure of subcutaneous tissue, [5] [7] hormones, [11] fibers (such as elastic fibers or elasticity) [7] and the skin barrier. [15]

The desire of many to look young for their age and/or attractive [6] has led to the establishment of a large cosmetics industry, [5] which is largely concerned with make-up that is applied on top of the skin (topically) to temporarily change appearance but it or dermatology also develop anti-aging products (and related products and procedures) that in some cases affect underlying biology and are partly applied preventively. [12] Facial traits are also used in biometrics [16] [17] and there have been attempts at reproducible quantifications. [7] [8] Skin health is considered a major factor in human well-being and the perception of health in humans. [12]

Genetics

Genes are a major factor in the particular appearance of a person's face with the high similarity of faces of identical twins indicating that most of facial variability is determined genetically. [18]

Studies have identified genes and gene regions determining face shape and differences in various facial features. A 2021 study found that a version of a gene associated with lip thickness – possibly selected for due to adaption to cold climate via fat distribution – introgressed from ancient humans – Denisovans – into the modern humans Native Americans. [19] [20] [21] Another study found look-alike humans (doppelgängers) have genetic similarities, sharing genes affecting not only the face but also some phenotypes of physique and behavior. [22] [23] A study identified genes controlling the shape of the nose and chin. [24] Biological databases may be used to aggregate and discover associations between facial phenotypes and genes. [25] [26]

Function

Emotional expression

Faces are essential to expressing emotion, consciously or unconsciously. A frown denotes disapproval; a smile usually means someone is pleased. Being able to read emotion in another's face is "the fundamental basis for empathy and the ability to interpret a person's reactions and predict the probability of ensuing behaviors". One study used the Multimodal Emotion Recognition Test [27] to attempt to determine how to measure emotion. This research aimed at using a measuring device to accomplish what many people do every day: read emotion in a face. [28]

The muscles of the face play a prominent role in the expression of emotion, [1] and vary among different individuals, giving rise to additional diversity in expression and facial features. [29]

People are also relatively good at determining if a smile is real or fake. A recent study looked at individuals judging forced and genuine smiles. While young and elderly participants equally could tell the difference for smiling young people, the "older adult participants outperformed young adult participants in distinguishing between posed and spontaneous smiles". [30] This suggests that with experience and age, we become more accurate at perceiving true emotions across various age groups.

Perception and recognition

The face perception mechanisms of the brain, such as the fusiform face area, can produce facial pareidolias such as this famous rock formation on Mars Martian face viking cropped.jpg

Gestalt psychologists theorize that a face is not merely a set of facial features, but is rather something meaningful in its form. This is consistent with the Gestalt theory that an image is seen in its entirety, not by its individual parts. According to Gary L. Allen, people adapted to respond more to faces during evolution as the natural result of being a social species. Allen suggests that the purpose of recognizing faces has its roots in the "parent-infant attraction, a quick and low-effort means by which parents and infants form an internal representation of each other, reducing the likelihood that the parent will abandon his or her offspring because of recognition failure". [31] Allen's work takes a psychological perspective that combines evolutionary theories with Gestalt psychology.

Biological perspective

Research has indicated that certain areas of the brain respond particularly well to faces. The fusiform face area, within the fusiform gyrus, is activated by faces, and it is activated differently for shy and social people. A study confirmed that "when viewing images of strangers, shy adults exhibited significantly less activation in the fusiform gyri than did social adults". [32] Furthermore, particular areas respond more to a face that is considered attractive, as seen in another study: "Facial beauty evokes a widely distributed neural network involving perceptual, decision-making and reward circuits. In those experiments, the perceptual response across FFA and LOC remained present even when subjects were not attending explicitly to facial beauty". [33]

Society and culture

Cosmetic surgery

Cosmetic surgery can be used to alter the appearance of the facial features. [34] Maxillofacial surgery may also be used in cases of facial trauma, injury to the face and skin diseases. Severely disfigured individuals have recently received full face transplants and partial transplants of skin and muscle tissue. [35]

Caricatures

Caricatures often exaggerate facial features to make a face more easily recognized in association with a pronounced portion of the face of the individual in question—for example, a caricature of Osama bin Laden might focus on his facial hair and nose; a caricature of George W. Bush might enlarge his ears to the size of an elephant's; a caricature of Jay Leno may pronounce his head and chin; and a caricature of Mick Jagger might enlarge his lips. Exaggeration of memorable features helps people to recognize others when presented in a caricature form. [36]

Metaphor

By extension, anything which is the forward or world-facing part of a system which has internal structure is considered its "face", like the façade of a building. For example, a public relations or press officer might be called the "face" of the organization he or she represents. "Face" is also used metaphorically in a sociological context to refer to reputation or standing in society, particularly Chinese society, [37] and is spoken of as a resource which can be won or lost. Because of the association with individuality, the anonymous person is sometimes referred to as "faceless".

<span class="mw-page-title-main">Smile</span> Conscious or unconscious facial muscular movement conveying happiness or pleasure

A smile is a facial expression formed primarily by flexing the muscles at the sides of the mouth. Some smiles include a contraction of the muscles at the corner of the eyes, an action known as a Duchenne smile. Among humans, a smile expresses delight, sociability, happiness, joy, or amusement. It is distinct from a similar but usually involuntary expression of anxiety known as a grimace. Although cross-cultural studies have shown that smiling is a means of communication throughout the world, there are large differences among different cultures, religions, and societies, with some using smiles to convey confusion, embarrassment or awkwardness.

Affective computing is the study and development of systems and devices that can recognize, interpret, process, and simulate human affects. It is an interdisciplinary field spanning computer science, psychology, and cognitive science. While some core ideas in the field may be traced as far back as to early philosophical inquiries into emotion, the more modern branch of computer science originated with Rosalind Picard's 1995 paper on affective computing and her book Affective Computing published by MIT Press. One of the motivations for the research is the ability to give machines emotional intelligence, including to simulate empathy. The machine should interpret the emotional state of humans and adapt its behavior to them, giving an appropriate response to those emotions.

A facial expression is one or more motions or positions of the muscles beneath the skin of the face. According to one set of controversial theories, these movements convey the emotional state of an individual to observers. Facial expressions are a form of nonverbal communication. They are a primary means of conveying social information between humans, but they also occur in most other mammals and some other animal species.

<span class="mw-page-title-main">Prosopagnosia</span> Cognitive disorder of face perception

Prosopagnosia, also known as face blindness, is a cognitive disorder of face perception in which the ability to recognize familiar faces, including one's own face (self-recognition), is impaired, while other aspects of visual processing and intellectual functioning remain intact. The term originally referred to a condition following acute brain damage, but a congenital or developmental form of the disorder also exists, with a prevalence of 2.5%. The brain area usually associated with prosopagnosia is the fusiform gyrus, which activates specifically in response to faces. The functionality of the fusiform gyrus allows most people to recognize faces in more detail than they do similarly complex inanimate objects. For those with prosopagnosia, the method for recognizing faces depends on the less sensitive object-recognition system. The right hemisphere fusiform gyrus is more often involved in familiar face recognition than the left. It remains unclear whether the fusiform gyrus is specific for the recognition of human faces or if it is also involved in highly trained visual stimuli. Prosopoagnosic patients are under normal conditions able to recognize facial expressions and emotions.

The fusiform gyrus, also known as the lateral occipitotemporal gyrus,is part of the temporal lobe and occipital lobe in Brodmann area 37. The fusiform gyrus is located between the lingual gyrus and parahippocampal gyrus above, and the inferior temporal gyrus below. Though the functionality of the fusiform gyrus is not fully understood, it has been linked with various neural pathways related to recognition. Additionally, it has been linked to various neurological phenomena such as synesthesia, dyslexia, and prosopagnosia.

Physical attractiveness is the degree to which a person's physical features are considered aesthetically pleasing or beautiful. The term often implies sexual attractiveness or desirability, but can also be distinct from either. There are many factors which influence one person's attraction to another, with physical aspects being one of them. Physical attraction itself includes universal perceptions common to all human cultures such as facial symmetry, sociocultural dependent attributes, and personal preferences unique to a particular individual.

Phakomatoses, also known as neurocutaneous syndromes, are a group of multisystemic diseases that most prominently affect structures primarily derived from the ectoderm such as the central nervous system, skin and eyes. The majority of phakomatoses are single-gene disorders that may be inherited in an autosomal dominant, autosomal recessive or X-linked pattern. Presentations may vary dramatically between patients with the same particular syndrome due to mosaicism, variable expressivity, and penetrance.

Pseudoxanthoma elasticum (PXE) is a genetic disease that causes mineralization of elastic fibers in some tissues. The most common problems arise in the skin and eyes, and later in blood vessels in the form of premature atherosclerosis. PXE is caused by autosomal recessive mutations in the ABCC6 gene on the short arm of chromosome 16 (16p13.1).

A dysmorphic feature is an abnormal difference in body structure. It can be an isolated finding in an otherwise normal individual, or it can be related to a congenital disorder, genetic syndrome or birth defect. Dysmorphology is the study of dysmorphic features, their origins and proper nomenclature. One of the key challenges in identifying and describing dysmorphic features is the use and understanding of specific terms between different individuals. Clinical geneticists and pediatricians are usually those most closely involved with the identification and description of dysmorphic features, as most are apparent during childhood.

Smoker's face describes the characteristic changes that happen to the faces of many people who smoke tobacco products. Smoking causes damage to the skin by depleting the skin of oxygen and nutrients.

Visual object recognition refers to the ability to identify the objects in view based on visual input. One important signature of visual object recognition is "object invariance", or the ability to identify objects across changes in the detailed context in which objects are viewed, including changes in illumination, object pose, and background context.

Memory supports and enables social interactions in a variety of ways. In order to engage in successful social interaction, people must be able to remember how they should interact with one another, whom they have interacted with previously, and what occurred during those interactions. There are a lot of brain processes and functions that go into the application and use of memory in social interactions, as well as psychological reasoning for its importance.

Emotion perception refers to the capacities and abilities of recognizing and identifying emotions in others, in addition to biological and physiological processes involved. Emotions are typically viewed as having three components: subjective experience, physical changes, and cognitive appraisal; emotion perception is the ability to make accurate decisions about another's subjective experience by interpreting their physical changes through sensory systems responsible for converting these observed changes into mental representations. The ability to perceive emotion is believed to be both innate and subject to environmental influence and is also a critical component in social interactions. How emotion is experienced and interpreted depends on how it is perceived. Likewise, how emotion is perceived is dependent on past experiences and interpretations. Emotion can be accurately perceived in humans. Emotions can be perceived visually, audibly, through smell and also through bodily sensations and this process is believed to be different from the perception of non-emotional material.

Progeroid syndromes (PS) are a group of rare genetic disorders that mimic physiological aging, making affected individuals appear to be older than they are. The term progeroid syndrome does not necessarily imply progeria, which is a specific type of progeroid syndrome.

The occipital face area (OFA) is a region of the human cerebral cortex which is specialised for face perception. The OFA is located on the lateral surface of the occipital lobe adjacent to the inferior occipital gyrus. The OFA comprises a network of brain regions including the fusiform face area (FFA) and posterior superior temporal sulcus (STS) which support facial processing.

Based on Walsh's phenotype analysis, King determined that one of the earliest paintings of Richard III, the 1510 "Arched Framed Portrait," best matched the genetic information. "We were still dealing with categories [of color] because we're not at the quantitative level yet," Walsh said of her determination of Richard III's hair and eye color. "[King] wanted something physical to see, and that's what spurred me to move toward the quantitative so strongly. Because I could always say to someone, 'blue' or 'blonde,' and they would say, 'I need to see this physically.' So that is what I'm working on now. I want to produce that result." Walsh has gathered DNA phenotype data from 2,000 Irish, Greek and U.S. individuals and is currently collecting data from 3,000 additional individuals from those same countries in order to create a phenotype-genotype database and prediction model. For forensic purposes, she would like to be able to start with a "blank person" and with a sample of DNA, determine the actual eye, hair and skin pigmentation.
