Ie'acus internus.—Ilio-trochuntineus.—A thick, fleshy,
fan-like muscle, occupying the internal surface of the iliac
portion of the os innominatum. It arises from the inner edge
of the crista of the ilium, and adheres to the concavity of that
bone down to the brim of the pelvis, to the fore part of the
bone under the spinous process. All its radiated fibres are ga-
thered together into a tendon under Poupart's ligament, where
it unites with the psoas, and the common tendon turns obliquely
round to be inserted into the lesser trochanter. It acts in
conjunction with the psoas in moving the thigh forwards.

MUSCLES SITUATED ON THE ANTERIOR PART
OF THE THORAX.

Pectoralis major.—Pectoralis. Sterno-humeralis.—A.
large, thick, and fleshy muscle which covers all the breast.
It arises from the clavicle next the sternum, ftom the edge
of the sternum and the cartilaginous endings of the fifth and
sixth ribs. All its fibres converge to form a flat twisted
tendon, which goes before the armpit, to be inserted into the
edge of the groove in the humerus for the tendon of the
biceps. When this muscle contracts, the arm is brought
forwards obliquely.

Cancer of the breast is situated over this muscle; and is
occasionally very firmly attached to it.

Si ECLAvius.—Subclaviunus.—A small muscle concealed
under the clavicle. It arises by a fiat tendon from the car-
tilage of the first rib, and is inserted fleshy into a great part
of the clavicle. Its use is to fix the clavicle more firmly.

Pectoralis minor,—Cosio-coracoidalis. Serratus minor
anticus.—This muscle lies underneath the pectoralis major,
