iev the ligament of the wrist to the palm of the hand, where
it sends off branches, in every direction, to the muscles of the
hand, and then supplies the digital nerves, which go to the ex-
tremities of the thumb, and fore and middle fingers.
5. The ulnar nerve, which descends between the bra-
chial artery and basilic vein, between the internal condyle of
the humerus, and the olecranon, and divides in the fore-arm,
into an internal and an external branch. The former passes
over the ligament of the wrist and sesamoid bone, to the
hand, where it divides into three branches, two of which go
to the ring and little finger, and the third forms an arch to-
wards the thumb, in the palm of the hand, and is lost in the
contiguous muscles. The latter passes over the tendon of the
extensor carpi uinaiis, and back of the hand, to supply also
the two last fingers.
6. The spiral, or radial nerve, which sometimes gives
off the axillary nerve. It pa»ses backwards, about the os hu-
meri, descends on the outside of the arm, between the bra-
chialis externus and interims muscles, to the cubit; then pro-
ceeds between the supinator longus and bievis, to the supe-
rior extremity of the radius, giving off various branches to ad-
jacent muscles. At this place it divides into two branches;
one goes along the radius, between the supinator longus, and
radians interims, to the back of the hand, an ! terminates in
the interosseous muscles, the thumb, and three first fingers ;
the other passes between the supinator brevis, and head of
the radius, and is lest in the muscles of the fore-arm.
DORSAL NERVES.
The dorsal nerves are twelve pairs in number. Trie first
pair gives off a branch to the brachial plexus. All the dorsal
nerves are distributed to the muscles of the back, ioterccstals,
