The others are the ciliary ganglion, the submandibular ganglion and the pterygopalatine ganglion.
It is one of four parasympathetic ganglia of the head and neck, the others being the submandibular ganglion, otic ganglion, and ciliary ganglion.

Parotid gland

parotidparotid salivary glandparotid glands
It is functionally associated with the glossopharyngeal nerve and innervates the parotid gland for salivation. Here, the fibres synapse, and the postganglionic fibers pass by communicating branches to the auriculotemporal nerve, which conveys them to the parotid gland.
Preganglionic parasympathetic fibers leave the brain stem from inferior salivatory nucleus in the glossopharyngeal nerve and then through its tympanic and then the lesser petrosal branch pass into the otic ganglion.

Infratemporal fossa

Mandibular nerve, inferior alveolar nerve, lingual nerve, buccal nerve, chorda tympani nerve, and otic ganglion.

(The others are the submandibular ganglion, pterygopalatine ganglion, and otic ganglion).

Parasympathetic nervous system

parasympatheticparasympathetic nerveparasympathetic nerves
The preganglionic parasympathetic fibres originate in the inferior salivatory nucleus of the glossopharyngeal nerve.
The tympanic plexus of nerves rejoin and form the lesser petrosal nerve and exit through the foramen ovale to synapse at the otic ganglion.

Glossopharyngeal nerve

It is functionally associated with the glossopharyngeal nerve and innervates the parotid gland for salivation. The preganglionic parasympathetic fibres originate in the inferior salivatory nucleus of the glossopharyngeal nerve.
Upon exiting the skull, the lesser petrosal nerve synapses in the otic ganglion, which is suspended from the mandibular nerve immediately below the foramen ovale.

Salivatory nuclei

inferior salivatory nucleussuperior salivatory nucleussuperior salivary nucleus
The preganglionic parasympathetic fibres originate in the inferior salivatory nucleus of the glossopharyngeal nerve.
The inferior salivatory nucleus innervates the parotid gland by way of the otic ganglion and forms the parasympathetic component of the glossopharyngeal nerve.

Auriculotemporal nerve

auriculotemporalauriculotemporal branch
Here, the fibres synapse, and the postganglionic fibers pass by communicating branches to the auriculotemporal nerve, which conveys them to the parotid gland.
The somatosensory root (superior) originates from branches of the mandibular nerve (cranial nerve V), which pass through the otic ganglion without synapsing.

Lesser petrosal nerve

Foramen petrosumlesser superficial petrosal nerve
They leave the glossopharyngeal nerve by its tympanic branch and then pass via the tympanic plexus and the lesser petrosal nerve to the otic ganglion.
It synapses in the otic ganglion, from where the postganglionic fibers emerge.

Medial pterygoid muscle

medial pterygoidmedialpterygoideus internus
It surrounds the origin of the nerve to the medial pterygoid. The motor fibers supplying the medial pterygoid and the tensor palati and the tensor tympani pass through the ganglion without relay.

The ganglion is connected to the chorda tympani nerve and also to the nerve of the pterygoid canal.
It passes forward through the pterygoid canal with its corresponding artery (artery of the pterygoid canal) and is joined by a small ascending sphenoidal branch from the otic ganglion.

Tensor veli palatini muscle

It is in relation, laterally, with the trunk of the mandibular nerve at the point where the motor and sensory roots join; medially, with the cartilaginous part of the auditory tube, and the origin of the tensor veli palatini; posteriorly, with the middle meningeal artery. The motor fibers supplying the medial pterygoid and the tensor palati and the tensor tympani pass through the ganglion without relay.
