Inferior tympanic canaliculus
Inferior Tympanic Canaliculus[edit | edit source]
The Inferior Tympanic Canaliculus is a small canal in the human body, specifically located in the temporal bone near the Carotid canal. It is a part of the human auditory system and plays a crucial role in transmitting the tympanic nerve to the tympanic cavity.
Anatomy[edit | edit source]
The inferior tympanic canaliculus is a minute canal that allows the passage of the tympanic branch of the glossopharyngeal nerve, also known as Jacobson's nerve. This nerve enters the tympanic cavity, also known as the middle ear, through the inferior tympanic canaliculus.
Function[edit | edit source]
The primary function of the inferior tympanic canaliculus is to provide a pathway for the tympanic nerve. This nerve is responsible for supplying parasympathetic fibers to the parotid gland via the lesser petrosal nerve.
Clinical Significance[edit | edit source]
Understanding the anatomy of the inferior tympanic canaliculus is crucial in various surgical procedures involving the ear, such as tympanoplasty and stapedectomy. Damage to this area can result in complications such as facial nerve paralysis and hearing loss.
