Facial canal

The facial canal (Canalis nervi facialis), also known as the Fallopian Canal,[1] first described by Gabriele Falloppio, is a Z-shaped canal running through the temporal bone from the internal acoustic meatus to the stylomastoid foramen. In humans it is approximately 3 centimeters long, which makes it the longest human osseous canal of a nerve.[2] It is located within the middle ear region, according to its shape it is divided into three main segments: the labyrinthine, the tympanic, and the mastoidal segment.[3] It contains Cranial Nerve VII, also known as the facial nerve.
