OTIC GANGLION
It is a small parasympathetic ganglion connected to the mandibular division of trigeminal nerve and provides a relay station to the secretomotor fibres to the parotid gland.
Topographically, it is intimately related to the mandibular nerve but functionally it is related to glossopharyngeal nerve.
Location
Infratemporal fossa, just below the foramen ovale.
Relations
Lateral: Mandibular nerve.
Medial: Tensor palati muscle.
Posterior: Middle meningeal artery.
Anterior: Medial pterygoid muscle.
Roots or Connections
1. Parasympathetic motor (secretomotor): From lesser petrosal nerve. Preganglionic parasympathetic fibres arise from inferior salivatory nucleus; pass successively through glossopharyngeal nerve, tympanic branch of glossopharyngeal nerve (Jacobson’s nerve), tympanic plexus, and lesser petrosal nerve to relay in the ganglion. Postganglionic parasympathetic fibres from ganglion cells pass through auriculo-temporal nerve to supply parotid gland.
2. Sympathetic: From sympathetic plexus around the middle meningeal artery. Preganglionic sympathetic fibres arise from T1 and T2 spinal segments, enter the cervical sympathetic chain at
the level of its inferior ganglion and then ascend to relay in the superior cervical sympathetic ganglion. The postganglionic fibres arise from this ganglion and form plexus around the middle meningeal artery. They then pass through the ganglion without relay to reach the parotid gland via auriculotemporal nerve. They are vasomotor in nature and responsible for thick salivary secretion.
3. Sensory: From auriculotemporal nerve.
4. Somatic motor: Nerve to medial pterygoid. It passes through ganglion to supply medial pterygoid, tensor palati, and tensor tympani muscles.

Ur wrng sir
Medially : mandibular nerve
Lateraly: tendor veli palatine

[@SmartMedLearnDrAnkitJain]

Dear please review standard book. Otic ganglion is related laterally with mandibular nerve and medially with TVP ms.
Some books like datta writes otic ganglion is located medial to trunk of mandibular nerve which also means ganglion is releted laterally with mandibular nerve. Ganglion is located lateral to tensor palatini ms. Which means ganglion is related medially with TVP ms

[@darshanrsinghchouhan0008]
