title: Histophysiology of the saccus vasculosus of the Indian freshwater goby Glossogobius giuris Ham. (Teleostei).
abstract: The author studied the structure and functions of the saccus vasculosus of the Indian freshwater goby Glossogobius giuris (Ham.). The saccus is ovoid, is localized on the ventral surface of the brain and is lodged between the inferior lobes. It consist of several loculi lined with coronet cells and is bathed with blood from surrounding sinusoids. The coronet cells are variably shaped and have a conspicous central nucleus. It is suggested that the purpose of the saccus vasculosus is to act as a storage site for carbohydrates to the brain. By converting glycogen to acid mucopolysaccharides, the coronet cells are involved in glycogen metabolism.
