Macroscopic and microscopic study of the mandibular salivary gland of Black Bengal goats

Abstract

The gross anatomy and microscopic structures of the mandibular salivary gland of 15 Black Bengal goats of either sex and different ages were carried out during the period from January 1999 to December 2000. The mandibular salivary gland was irregularly triangular in shape and was situated ventral and caudal part of the angle of the mandible and partly covered by the ventral part of the parotid gland. The gland was cream colored in fresh condition and the lobules were coarser and less compact in texture. The   mandibular duct left the gland near the middle of the cranio-dorsal border and opened into the caruncula sublingualis with the sublingual duct in common. The average length of the duct was 11 cm. The branches of external carotid, lingual and occipital arteries supplied the mandibular salivary gland. The mandibular gland was drained by the lingofacial and lingiual veins and occasionally by the laryngeal vein. It was mixed tubulo-alveolar gland and consisted to numerous lobes and lobules; supported by connective tissue capsule. The mixed alveoli were more than the isolated serous and mucous alveoli.
