The otic ganglion is a small parasympathetic ganglion located immediately below the foramen ovale in the infratemporal fossa and on the medial surface of the mandibular nerve. It is functionally associated with the glossopharyngeal nerve and innervates the parotid gland for salivation. It is one of four parasympathetic ganglia of the head and neck.
The auriculotemporal nerve arises from the posterior division of [2]: 497 the mandibular nerve (CN V 3) (which is itself a branch of the trigeminal nerve (CN V)). [3] It arises by two roots [2]: 497 that circle around either side of the middle meningeal artery [1] [2]: 363 before uniting to form a single nerve.
Because the vestibulocochlear nerve is in proximity to the geniculate ganglion, it may also be affected and patients may also experience: [citation needed] tinnitus; hearing loss; hyperacusis; vertigo; The swallow reflex might also be affected. Involvement of the trigeminal nerve can cause numbness of the face. [citation needed]
Its parasympathetic root is derived from the nervus intermedius (a part of the facial nerve) through the greater petrosal nerve.. In the pterygopalatine ganglion, the preganglionic parasympathetic fibers from the greater petrosal branch of the facial nerve synapse with neurons whose postganglionic axons, vasodilator, and secretory fibers are distributed with the deep branches of the trigeminal ...

The submandibular ganglion is small and fusiform in shape. It is situated above the deep portion of the submandibular gland, on the hyoglossus muscle, near the posterior border of the mylohyoid muscle. The ganglion 'hangs' by two nerve filaments from the lower border of the lingual nerve (itself a branch of the mandibular nerve, CN V 3). It is ...
Each has three roots entering the ganglion and a variable number of exiting branches. The motor root carries presynaptic parasympathetic nerve fibers ( GVE ) that terminate in the ganglion and synapse with the postsynaptic fibers that, in turn, project to target organs.
