arise in the palm of the hand, from the tendons of the pro-
fundus : their small tendons reach the middle of the second
phalanx. They are chiefly useful in performing the quick
short motions of the fingers on musical instruments, &c.
Flexor brevis pollicis manus.—Carpo-phalange us polli-
cis. Flexor secundi internodii.—A two-headed muscle, si-
tuated on the inside of the thumb; one head arises from the
os trapezium, the other from the os magnum. They are in-
serted into the sesamoid bones, and edge of the first bone of
the thumb. The use of this muscle is to bend the first joint
ef the thumb.
Opponens pollicis.—Flexor ossis metacarpipollicis* Car-
po-metacarpevs pollicis.—Lies under the abductor pollicis,
arising from the os scaphoidej and ligament of the wrist. It
is inserted into the fore part of the metacarpal bone of the
thumb. It bends the thumb, as in clenching the fist.
Abductor pollicis manus.—Curpo-super-phalangeus pol-
licis.—This muscle lies immediately under the common in-
teguments : it arises from the annular ligament of the wrist>
and from the os scaphoides; then bends gradually round the
thumb, to be inserted into the first bone of the thumb. A
^second muscle is described by Albinus, by the same name-.
It pulls the thumb from the fingers.
Adductor pollicis manus.—Mctacarpo-phaiangeus polli-
,eis.—The metacarpal bone of the middle finger gives origin
to this triangular muscle ; it goes directly across to meet the
thumb, and is inserted into the root of the first phalanx. It
draws the thumb towards the fore-finger..
Abductor indicis manus.—A flat and broad muscle : it
arises from the 03 trapezium, and the first bone of the thumb,
and is inserted into the back part of the first bone of the-
finger, which it pulls forwards towards the thumb.
