cisterna

An enclosed space acting as a fluid reservoir. The cisterna magna is a space filled with cerebrospinal fluid lying between the CEREBELLUM and the MEDULLA OBLONGATA.

cisterna

The supranuclear cytoplasm of dog epididymal principal cells was characterized by the presence of the Golgi apparatus, scattered cisternae of the rough endoplasmic reticulum, multivesicular bodies, mitochondria and some lysosomes, characteristics also observed in other studies for the rat epididymis (Robaire & Hermo; Hermo, 1995).
Vicentini & Orsi postulated that the supranuclear cytoplasm of the epididymal principal cells of the golden hamster mainly consists of a well-developed Golgi apparatus, which is formed by lamellar cisternae that extend into small and clear apical vacuoles arranged in the form of a supranuclear necklace and with cis-trans ends.
Principal cells possess a well-developed Golgi apparatus and numerous rough endoplasmic reticulum cisternae, suggesting that these cells are able to synthesize and secrete proteins or glycoproteins, similarly to what is observed for other mammalian species (Hamilton; Robaire & Hermo; Goyal & Williams, 1991; Arrighi et al.).
