Mansouri, S.H. and Mehrabi, J. 2001. Ultrastructural aspects of buffalo submandibular glands. J. Appl. Anim. Res., 19: 225–232.
Submandibular glands of five adult male buffaloes were examined by conventional electron microscopic technique. The glands were compound tubulo-acinar in nature and consisted of serous, mucous and seromucous secretory units. Mucous secretory cells were predominant. Few microvilli were seen at the luminal surface of the secretory units of the gland. The mucous cells contained scattered mitochondria, parallel and nondilated cisternae of rough endoplasmic reticulum, non-developed Golgi apparatus and a large number of the secretory granules, mostly fused. The secretory serous cells and demilunes consisted of a large number of electron-lucent secretory granules and a few secretory granules with electron dense matrix. In addition, the cells contained rough endoplasmic reticulum and free ribosomes. Other organelles were sparse. Basal striations were the main characteristics of the submandibular striated duct cells.
