The occipital bone is a cranial dermal bone and the main bone of the occiput. It is trapezoidal in shape and curved on itself like a shallow dish. The occipital bone overlies the occipital lobes of the cerebrum. At the base of skull in the occipital bone, there is a large oval opening called the foramen magnum, which allows the passage of the spinal cord.
The inferior alveolar nerve is a branch of the mandibular nerve, which is itself the third branch of the trigeminal nerve. The inferior alveolar nerves supply sensation to the lower teeth.
A comb is a fleshy growth or crest on the top of the head of gallinaceous birds, such as turkeys, pheasants, and domestic chickens. Its alternative name cockscomb reflects that combs are generally larger on males than on females. There can be several fleshy protuberances on the heads and throats of gallinaceous birds, i.e. the comb, wattle, and earlobe, which collectively are called caruncles, however, in turkeys caruncle refers specifically to the fleshy nodules on the head and throat.
The geniohyoid muscle is a narrow muscle situated superior to the medial border of the mylohyoid muscle. It is named for its passage from the chin to the hyoid bone.
The superior sagittal sinus, within the human head, is an unpaired area along the attached margin of the falx cerebri. It allows blood to drain from the lateral aspects of anterior cerebral hemispheres to the confluence of sinuses. Cerebrospinal fluid drains through arachnoid granulations into the superior sagittal sinus and is returned to venous circulation.
In human anatomy, the facial skeleton of the skull the external surface of the mandible is marked in the median line by a faint ridge, indicating the mandibular symphysis or line of junction where the two lateral halves of the mandible typically fuse at an early period of life. It is not a true symphysis as there is no cartilage between the two sides of the mandible.
The transverse sinuses, within the human head, are two areas beneath the brain which allow blood to drain from the back of the head. They run laterally in a groove along the interior surface of the occipital bone. They drain from the confluence of sinuses to the sigmoid sinuses, which ultimately connect to the internal jugular vein. See diagram : labeled under the brain as "SIN. TRANS.".
The inferior alveolar artery is an artery of the face. It is a branch of the first portion of the maxillary artery.
Mental nerve is a sensory nerve which provides sensation to the front of the chin and lower lip as well as the labial gingivae of the mandibular anterior teeth and the premolars. It is a branch of the posterior trunk of the inferior alveolar nerve, which is itself a branch of the mandibular division of the trigeminal nerve.
The squamous part of occipital bone, is situated above and behind the foramen magnum, and is curved from above downward and from side to side.
Along the internal surface of the occipital bone, at the point of intersection of the four divisions of the cruciform eminence is the internal occipital protuberance. Running transversely on either side is a groove for the transverse sinus.
Near the middle of the squamous part of occipital bone is the external occipital protuberance, the highest point of which is referred to as the inion. The inion is the most prominent projection of the protuberance which is located at the posterioinferior part of the human skull. The nuchal ligament and trapezius muscle attach to it.
The marginal mandibular branch of the facial nerve passes forward beneath the platysma and depressor anguli oris, supplying the muscles of the lower lip and chin, and communicating with the mental branch of the inferior alveolar nerve.
The human chin refers to the forward pointed part of the anterior mandible below the lower lip. A fully developed human skull has a chin of between 0.7 cm and 1.1 cm. While some more obese people may appear to have a “double chin”, this is only a facial feature of the neck where multiple layers of skin build up.
Anthropological criminology is a field of offender profiling, based on perceived links between the nature of a crime and the personality or physical appearance of the offender. Although similar to physiognomy and phrenology, the term "criminal anthropology" is generally reserved for the works of the Italian school of criminology of the late 19th century. Lombroso thought that criminals were born with detectable inferior physiological differences. He popularized the notion of "born criminal" and thought that criminality was a case of atavism or hereditary disposition. His central idea was to locate crime completely within the individual and divorce it from surrounding social conditions and structures. A founder of the Positivist school of criminology, Lombroso opposed the social positivism developed by the Chicago school and environmental criminology.
The mandibular symphysis divides below and encloses a triangular eminence, the mental protuberance, the base of which is depressed in the center but raised on either side to form the mental tubercle. The two mental tubercles along with the medial mental protuberance are collectively called the mental trigone.
Neanderthal anatomy differed from modern humans in that they had a more robust build and distinctive morphological features, especially on the cranium, which gradually accumulated more derived aspects, particularly in certain isolated geographic regions.
In anatomy, the mandible, lower jaw or jawbone is the largest, strongest and lowest bone in the human facial skeleton. It forms the lower jaw and holds the lower teeth in place. The mandible sits beneath the maxilla. It is the only movable bone of the skull. It is connected to the temporal bone by the temporomandibular joint.
A frontal shield, also known as a facial shield or frontal plate, is a feature of the anatomy of several bird species. Located just above the upper mandible, and protruding along the forehead, it is composed of two main parts: a hard, proteinaceous callus and a soft, fleshy corium. It is thought to play roles in protection, mate identification, sexual selection, and territorial defense.
Stellasaurus is a genus of centrosaurine ceratopsid dinosaur that lived in Montana during the Late Cretaceous. The type and only species is Stellasaurus ancellae. Its remains have been found in the Late Campanian age Two Medicine Formation, the same geological unit which its relatives Rubeosaurus, Einiosaurus, and Achelousaurus were discovered in.
