Intercellular Secretory Canaliculi in the Feline Laryngeal Gland

Laryngeal glands of adult cats were observed by scanning electron microscopy. Intercellular secretory canaliculi in the gland were an arborized system of capillaries extended among acinar cells, and their stem or collecting canaliculus opened to the gland lumen. The inner surface of the canaliculi was provided with small globular microvilli. The canaliculi in the laryngeal gland resembled the hepatic bile capillaries in lower vertebrates.
