Facial Nerves (VII)
The "facial"nerves" are the seventh pair of cranial nerves and are,
therefore, numbered "VII." They arise from the lower part of the pons at
the base of the brain stem and emerge on the sides of the face. Their
sensory branches are associated with taste receptors on the front
two-thirds of the tongue, and some of the motor fibers send impulses to
muscles for facial expressions. Other fibers function involuntarily by
stimulating the tear gland and some saliva glands (submandibular,
sublingual, and parotid salivary glands). The facial nerves from the brow
to the throat under the chin include: (1) the temporal nerve, (2) the
zygomatic nerve, (3) the buccal nerve, (4) the facial nerve, (4) the
posterior auricular nerve, (5) mandibular nerve, and (6) the cervical
nerve.
