Terminologia Embryologica

Last updated

The Terminologia Embryologica (TE) is a standardized list of words used in the description of human embryologic and fetal structures. It was produced by the Federative International Committee on Anatomical Terminology on behalf of the International Federation of Associations of Anatomists and posted on the Internet since 2010. [1] It has been approved by the General Assembly of the IFAA during the seventeenth International Congress of Anatomy in Cape Town (August 2009).

The Federative International Committee for Anatomical Terminology (FICAT) is a group of experts who review, analyze and discuss the terms of the morphological structures of the human body. It was created by the International Federation of Associations of Anatomists, and was originally known as the Federative Committee on Anatomical Terminology (FCAT).

The International Federation of Associations of Anatomists (IFAA) is an umbrella scientific organization of national and multinational Anatomy Associations, dedicated to anatomy and biomorphological sciences.


It is analogous to the Terminologia Anatomica (TA), which standardizes terminology for adult human anatomy and which deals primarily with naked-eye adult anatomy. It succeeds the Nomina Embryologica, which was included as a component of the Nomina Anatomica. [2] [3]

Terminologia Anatomica (TA) is the international standard on human anatomic terminology. It was developed by the Federative Committee on Anatomical Terminology (FCAT) and the International Federation of Associations of Anatomists (IFAA) and was released in 1998. It supersedes the previous standard, Nomina Anatomica. Terminologia Anatomica contains terminology for about 7500 human gross (macroscopic) anatomical structures. In April 2011, Terminologia Anatomica was published online by the Federative International Programme on Anatomical Terminologies (FIPAT), the successor of FCAT.

Nomina Anatomica (NA) was the international standard on human anatomic terminology from 1955 until it was replaced by Terminologia Anatomica in 1998.

It was not included in the original version of the TA. [4]

The Terminologia Histologica (TH) is a controlled vocabulary for use in cytology and histology. In April 2011, Terminologia Histologica was published online by the Federative International Programme on Anatomical Terminologies (FIPAT), the successor of FCAT.

Fascia layer of fibrous connective tissue that surrounds muscles, blood vessels and nerves

A fascia is a band or sheet of connective tissue, primarily collagen, beneath the skin that attaches, stabilizes, encloses, and separates muscles and other internal organs. Fascia is classified by layer, as superficial fascia, deep fascia, and visceral or parietal fascia, or by its function and anatomical location.

Locus coeruleus Stress & Panic Reponse Center

The locus coeruleus is a nucleus in the pons of the brainstem involved with physiological responses to stress and panic. It is a part of the reticular activating system.

Buccinator muscle

The buccinator is a thin quadrilateral muscle occupying the interval between the maxilla and the mandible at the side of the face. It forms the anterior part of the cheek or the lateral wall of the oral cavity.

Thyroid cartilage

The thyroid cartilage is the largest of the nine cartilages that make up the laryngeal skeleton, the cartilage structure in and around the trachea that contains the larynx. It does not completely encircle the larynx; only the cricoid cartilage does.

Iris dilator muscle

The iris dilator muscle, is a smooth muscle of the eye, running radially in the iris and therefore fit as a dilator. The pupillary dilator consists of a spokelike arrangement of modified contractile cells called myoepithelial cells. These cells are stimulated by the sympathetic nervous system. When stimulated, the cells contract, widening the pupil and allowing more light to enter the eye.

Anconeus muscle

The anconeus muscle is a small muscle on the posterior aspect of the elbow joint.

Ilium (bone) uppermost and largest part of the hip bone, and appears in most vertebrates (including mammals and birds), but not bony fish or snakes

The ilium is the uppermost and largest part of the hip bone, and appears in most vertebrates including mammals and birds, but not bony fish. All reptiles have an ilium except snakes, although some snake species have a tiny bone which is considered to be an ilium.

Ligamentum venosum

The ligamentum venosum is the fibrous remnant of the ductus venosus of the fetal circulation. Usually, it is attached to the left branch of the portal vein within the porta hepatis. It may be continuous with the round ligament of liver.

Annular ligament of radius

The annular ligament is a strong band of fibers that encircles the head of the radius, and retains it in contact with the radial notch of the ulna.

Inferior tibiofibular joint

The distal tibiofibular joint is formed by the rough, convex surface of the medial side of the distal end of the fibula, and a rough concave surface on the lateral side of the tibia.

Accessory meningeal artery branch of the maxillary artery

The accessory meningeal artery is a branch of the maxillary artery, sometimes derived from the middle meningeal artery.

Cruciate ligament of atlas

The cruciform ligament of atlas is a cruciate ligament in the neck forming part of the atlanto-axial joint. The ligament is named as such because it is in the shape of a cross.

Anatomical terminology is a form of scientific terminology used by anatomists, zoologists, and health professionals such as doctors.

The venous plexus of hypoglossal canal (TA) – also known as plexus venosus canalis nervi hypoglossi (TA), circellus venosus hypoglossi and rete canalis hypoglossi – is a small venous plexus around the hypoglossal nerve that connects with the occipital sinus, the inferior petrosal sinus and the internal jugular vein. Occasionally, it may be a single vein rather than a venous plexus.
