Otic ganglion

Last revised by Yoshi Yu on 9 Apr 2023

The otic ganglion is one of four parasympathetic ganglia of the head and neck. It receives parasympathetic fibers from the glossopharyngeal nerve. It supplies the parotid gland with not just parasympathetic, but also sympathetic and sensory fibers that pass through the gland.
