Microanatomical Studies on the Trachea in Partridge

Abstract

Trachea was collected from six adult male partridge of Tirunelveli district. Aim of the study is to find out the microanatomical details of trachea in partridge birds. Trachea was lined by a pseudostratified ciliated columnar epithelium. Lamina propria was made up of loose connective tissue and contained alveolar mucous glands. The submucosa contained elastic fibres and found in connection with perichondrium of cartilaginous rings. The cartilaginous rings were flattened in cross section. Thin tunica adventitia covered the cartilaginous rings. Trachealis muscle was absent.
