Use and meaning of the anatomical terms plexus choroideus and tela choroidea in veterinary and human medicine.

The anatomical terms plexus chor(i)oideus (CP) and tela chor(i)oidea (TC) are listed without explanations in the official nomenclature handbooks Terminologia Neuroanatomica and Nomina Anatomica Veterinaria. Definitions of CP and TC exhibit discrepancies in medical dictionaries and anatomy handbooks. The aim of our study was to analyse this problem in detail and to discuss a possible unified use of the terms in science and teaching.
