Abstract

The aim of this study was to describe the gross study, morphometry, histology and histochemistry of the lacrimal gland.A total number of six goat heads with an average age ranged from (7-9) months were collected from the corporation slaughter house, Chennai. It was a holocrine compound tubuloalveolar gland. Thin connective tissue capsule surrounded the gland and septa divided the gland to lobes and lobules. The acini were lined with a single layer of columnar cells with small intracytoplasmic eosinophilic vacuoles apically and spherical nucleus with prominent nucleolus basally which were frequently binucleated. Long fusiform myoepithelial cells with elongated nucleus were found between the basal surface of the epithelial cells and the basement membrane. Duct system started with intralobular and then interlobular duct and was drained with main excretory duct which opened as lacrimal ducts.Intralobular duct was lined with columnar epithelium. They converged into interlobular duct to join the main collectingduct.

Key words: Goat, Lacrimal Gland, Morphology, Histology
