Terminologia Embryologica

Standardized list of words used in the description of human embryologic and fetal structures

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).

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]

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