Gross Morphological Changes of Nasal Conchae in Pre and Postnatal Non-Descript Goats (Capra hircus)

Abstract

Studies on sequential gross morphological changes of nasal conchae were conducted in prenatal and
post-natal goats (group I-VI). The dorsal and middle nasal concha were attached caudally to the cribriform plate
of ethmoid bone and rostrally extended up to the level of the third transverse ruga of hard palate and 2nd molar
tooth, respectively. The ventral nasal concha was fusiform in shape and extended from mid third molar tooth to
alar fold rostrally. The dorsal nasal concha was shorter than ventral nasal concha in goats of prenatal groups
and vice-versa in post-natal groups. In coronal sections, structures of the nasal conchae were similar in all age
groups, and there was consistent increase in luminal diameter of conchal sinus from group I to VI.
