NERVI PATHETICI.

The fourth pair, or the pathetic nerves, arise from the crura
of the cerebellum laterally, pass forward, pierce the dura
mater below the third pair, and proceed with them through
the orbital fissure, to be inserted into the trochlcaiis muscle
of the eye.

NERVI TRIGEMINL

Theffth pair, or trigemni, arise from the anterior part of
the crura of the cerebellum, aud are divided within the cavity
of the cranium into three blanches, viz. the ophthalmic or
orbital, and the superior and inferior maxillary.

The orbital nerve gives off a branch, near its origin, which
unites with a branch of the sixth pair, to form the great inter-
costal nerve ; it then divides into three branches :

1. The frontal, which goes through the superciliary fora-
men to the muscles and integuments of the forehead.

2. The lachrymal, which goes to the lachrymal gland.

3. The nasal, which goes forwards to the inner cantlius of the
eye, where it gives off'a branch or two, then returns into the
cranium, and passes through the cribriform plate of the eth-
moid bone, and is distributed on the pituitary membrane.

The superior maxillary nerve goes through the foramen
rotundam, and is divided into—

1. The spkaeno-palatine, which goes through the sphamo-
palatine foramen, sends twigs to the internal pterygoid muscle,
then eaters the. cavity of the nostrils, and is lost on the Eusta-
chian tube, soft palate,'and pituitary sinus of the sphxneid
bone. .
