Lost and found anatomical terms: Crista choanalis vomeris.

摘要

Pars cuneiformis vomeris and Crista choanalis are morphological structures on the vomer listed in the current official anatomical nomenclature, Terminologia anatomica, but are either not mentioned or incorrectly described in different anatomical books. The term Crista choanalis vomeris was originally proposed by Drago Perovic in 1958 to describe the vertical crest beginning at the angle of the alae vomeris, running downwards to the posterior free margin of the vomer. Perovic also described the part of the vomer behind this crest was shaped as a cone, and termed it Pars cuneiformis vomeris. Because of their important contributions to the function of the respiratory pathway, Crista choanalis vomeris and Pars cuneiformis vomeris deserve proper definitions in the anatomical terminology.
