|Latin||canalis nervi facialis, canalis facialis|
The facial canal (Canalis nervi facialis)(also known as the Fallopian Canal – 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.[dubious ] 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. It contains Cranial Nerve VII, also known as the facial nerve.
