Serrati, pectoral, abdominal muscles, and diaphragm. The
five inferior pairs go to the cartilages of the ribs, and are
called costal.

LUMBAR NERVES.

The five pair of lumbar nerves are bestowed about the loins
and its muscles, the skin of the abdomen and loins, scrotum,
ovaria, and diaphragm. The second, third, and fifth pair
unite, and form the obturator nerve, which descends over the
psoas muscle into the pelvis, and passes through the foramen
thyroideum to the obturator muscle, triceps, pectineus, &fc

The third and fourth, with some branches of the second
pair, form the crural nerve, which passes under PoupartV
ligament with the femoral artery, sends off'branches to the
adjacent parte, and descends in the direction of the sartorius
muscle, to the internal condyle of the femur, from whence it
accompanies the saphena vein to the internal ankle, to be lost
in the skin of the great toe.

The fifth pair are joined to the first pair of the sacral nerves.

SACRAL NERVES.

The posterior sacral nerves go through the foramina at the
back of the sacrum, to supply the gluteal muscles and intcgu.
ments.

There are rive pair of anterior sacral nerves anteriorly, aH
of which arise from the cauda equina, or termination of the
medulla spinalis; so called from the nerves resembling the
tail of a horse. The four first pair give off branches to the
pelvic viscera, and are afterwards united to the last lumbar,
to form' a large plexus, which gives off—»

The ischiatic nerve, the largest in the body, which im-
mediately at its origin sends off branches to the bladder, rec-
