| Abstract | ||
| The lateral nasal diverticulum is a unique anatomical structure characteristic of dromedaries. However, little known about the anatomy and histology of this diverticulum. The aim of this study was to investigate the macroscopic and microscopic structure of the lateral nasal diverticulum in camels, and to elucidate its possible functions, A total of ten camel heads were used for this study. Grossly, it comprised of intranasal and intramuscular parts, both of which located mostly within the nasal vestibule. It started at the nasal opening, at the junction of vestibular skin and the mucus membrane of nasal cavity proper. It ended as blind sac near the infraorbital foramen. Histologically, it was lined by stratified columnar epithelium with goblet cells. The mucosa presented a number of crypts and clefts. The submucosal glands were well developed and mostly of serous type. The lateral nasal diverticulum aid in narial closure, humidification of nasal mucosa, and detection of olfactory cues as a possible function in dromedaries. | ||
