Ultrastructure of the Secretory Epithelial Cells of the Bulbo-Urethral Glands (Cowper's gland) in the Indian Fruit Bat, Rousettus leschenaulti (Desmarest) During the Reproductive Cycle International Journal of Morphology
Nerkar,Archana A; Gujar,Maher P; Gadegone,Mohan M.
The present paper describes the ultrastructural characteristics of the bulbo-urethral gland (Cowper' glands) of the Indian fruit bat, R. leschenaulti during sexually inactive-breeding cycle. Cyclic histological changes during the seasonal breeding quiescence cycle are not well marked. There are no marked differences. The ultrastructural characteristic of the secretory epithelial cells of Bulbo-Uretrhal Gland gland have been studied during different phases of reproductive cycle. The secretory epithelial cells are characterized by the well-developed rough endoplasmic reticulum, extensive developed complexus golgiensis (Golgi apparatus) and mitochondria. Mitochondria with lamellate cristae are dispersed in the cytoplasm. Three different types of secretory...

Ultrastructural Characterization of the Pars Distalis of the Indian Female Sheath-Tailed Bat, Taphozous longimanus (Hardwicke) International Journal of Morphology
Nerkar,Archana A; Gadegone,Mohan M.
The present ultrastructural observations demonstrate the presence of six cell types in the pars distalis of non-pregnant and pregnant bats of Taphozous longimanus. In the pars distalis of T. longimanus, STH cells are round to oval with eccentrically placed nucleus, numerous secretory granules and well developed Golgi indicate a cell under vigorous synthetic activity while those filled with secretory granules with reduced Golgi complex suggest reserve or storage state of cells. LTH cell is characterized by the large secretory granules, dilated endoplasmic reticulum and numerous mitochondria in the cytoplasm which indicate that these cells are hypertrophied and synthetically very active during pregnancy. ACTH cells are found either singly or in groups and...
