Otic ganglion 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. These pathways provide an alternate pathway of taste from the anterior two thirds of the tongue. These fibers do not pass through the middle ear. Frey's syndrome in which salivation will induce perspiration at the parotid region, accompanied by erythema. Otic ganglion 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.
Otic vesicle and can be subdivided into sensory, non-sensory, and neurogenic components. Sensory epithelial cells and neurons are derived from the proneurosensory domain. This domain can be further sub-categorized into the neurogenic sub-domain and prosensory sub-domain. Prosensory sub-domain eventually gives rise to the support cells and hair cells while the neurogenic sub-domain gives rise to the auditory neuron and vestibular neuron. The middle part of the otic vesicle develops into the ductus and saccus endolymphaticus. The anterior end of the otic vesicle gradually elongates as a tube and coils upon itself forming the beginnings of the cochlear duct. The vestibular extremity subsequently
