748. The ABDUCENTES (sixth pair) passes through the opening by which
the carotid artery enters the cranial cavity. It is the smallest of
the cerebral nerves, and is appropriated to the external straight
muscle of the eye.

749. The PORTIO MOLLIS (seventh pair) enters the hard portion of the
_tem'po-ral_ bone at the internal auditory opening, and is distributed
upon the internal ear. (Fig. 147, 148.)

[Illustration: Fig. 127. A representation of the distribution of the
eighth pair of nerves with some branches of the fifth. 1, 2, 3, 5, 7, 9,
Are branches of the eighth pair. They are distributed over the face in a
radiated manner, which constitutes the pes anserinus, (foot of a goose.)
The nerves 4, 6, 8, are branches of the fifth pair. 10, 11, 12, 13, 14,
15, 16, Are branches of nerves from the upper part of the spinal cord,
(cervical.)]

750. The FACIAL NERVE (eighth pair) passes from the skull through an
opening situated below the ear, (_mas'toid foramen_.) It is
distributed over the face, supplying the muscles with nervous
filaments.

751. The GLOSSO-PHARYNGEAL NERVE (ninth pair) passes from the brain,
through an opening with the jugular vein, (_foramen lac'e-rum_.) It is
distributed to the mucous membrane of the tongue and throat, and also
to the mucous glands of the mouth.
