Preferred Label : chorda tympani branch of facial nerve;
Uberon definition : The chorda tympani is a nerve that branches from the facial nerve (cranial nerve VII)
inside the facial canal, just before the facial nerve exits the skull via the stylomastoid
foramen. Chorda tympani is a branch of the facial nerve (the seventh cranial nerve)
that serves the taste buds in the front of the tongue, runs through the middle ear,
and carries taste messages to the brain. The chorda tympani is part of one of three
cranial nerves that are involved in taste. The taste system involves a complicated
feedback loop, with each nerve acting to inhibit the signals of other nerves. The
chorda tympani appears to exert a particularly strong inhibitory influence on other
taste nerves, as well as on pain fibers in the tongue. When the chorda tympani is
damaged, its inhibitory function is disrupted, leading to less inhibited activity
in the other nerves.;
