Comparative Gross and Histological Studies on Nasal Cavity of Black Bangal Goat and Garole Sheep

Abstract

In the present study tissue samples were collected from external naris, nasal cavity of six healthy adult black Bengal and Garole sheep for gross and histological observations. There was no much variation detected in gross structures of nostril and nasal cavity in two species. The outer most surface of naris of goat and sheep was lined by stratified squamous epithelium and nasal cavity was lined by ciliated psudostratified columnar epithelium. Nasal epithelium showed several cell types including ciliated, secreting, basal and brush cells. The distribution of glands was more in sheep as compared to goat.
