    muscle to supply the parietes of the abdomen. These branches inosculate with the intercostal arteries above, the ilio-lumbar and circumflexa ilii below, and the internal mammary and epigas- tric in front. The circumflexa ilii artery arises from the external iliac artery close to Poupart's ligament, and passes outwards behind that ligament to the crest of the ilium, and along the crest to its pos- terior part, where it inosculates with the ilio-lumbar artery. In its course, the artery pierces the crural sheath, and then lies be- tween the transversalis muscle and fascia ; near its termination it pierces the transversalis, and becomes placed between it and the internal oblique. An ascending branch is given off near the an- terior superior spine of the ilium; this branch ascends in the cel- lular interval between the internal oblique and transversalis, and inosculates with the other arteries of the parietes. The epigastric artery arises from the front of the external iliac artery a little above the circumflexa ilii; it bends inwards, and then ascends obliquely between the transversalis fascia and peri- toneum to the lower margin of the sheath of the rectus. Pierc- ing the transversalis fascia, it enters the sheath and ascends be- hind the rectus muscle to its upper part, where (in the substance of the muscle) it inosculates with the internal mammary artery. In the first part of its course the artery lies internally to the in- ternal abdominal ring, below the spermatic cord, and above the femoral ring. When the abdominal parietes are examined from within, the epigastric artery ^\\\\ be seen to form a prominent ridge, which divides the iliac fossa into an internal and external portion. It is in the former that direct inguinal hernia occurs ; in the latter oblique inguinal hernia. The branches of the epigastric artery are :— A cremasteric branch which accompanies the spermatic cord, and after supplying the cremaster muscle inosculates with the spermatic artery. A pubic branch, which is distributed behind the pubes, and sends a small branch of communication downwards to the obtu- rator artery. 3Iuscular branches, which pass outwards between the abdomi- nal muscles, and inosculate with the circumflexa ilii, lumbar, and intercostal arteries. Superficial branches, which are distributed to the integument of the ai)domen. The internal mammary artery, a branch of the subclavian, is situated in the ^leath of the rectus. It supplies the upper part of that muscle, and inosculates with the epigastric, iutercostals, and lumbar arteries. The VKiNS accompanying the arteries of the abdominal parietes
