HISTOLOGY: SALIVARY GLANDS
Indentify; Mucous Cells (Mucous Acini) and Serous Demilunes (Serous Acini)
The facial nerve is the seventh (VII) of twelve paired cranial nerves. It emerges from the brainstem between the pons and the medulla, and controls the muscles of facial expression, and functions in the conveyance of taste sensations from the anterior two-thirds of the tongue and oral cavity. It also supplies preganglionic parasympathetic fibers to several head and neck ganglia.
The (Z) zygomaticotemporal branch and the (C) cervicofacial branch of the facial nerve are dissected out during resection of a parotid tumor. The pes (goose's foot) is visible in this photograph.
PAROTID GLAND AND DUCT... PLUS THE SUBMANDIBULAR GLAND AND SUBLINGUAL GLAND
The paired parotid glands are the largest of the salivary glands. They are each found wrapped around the mandibular ramus, and secrete saliva through Stensen's ducts into the oral cavity, to facilitate mastication and swallowing and to begin the digestion of starches.
