Arteries

The external iliac artery admits of being tied in a surgical operation at any part except near its upper and lower end ; the near neighbourhood of the upper end being excepted on account of the circulation through the internal iliac, and the lower end on account of the common position of the branches (epigastric and circumflex iliac). Occasional deductions from this statement occur in consequence of a branch or branches taking origin near or at the middle of the artery; and as the operator may see such a branch he will avoid placing a ligature very near it.

The gluteal artery,[a. glutaea] (iliaca posterior, — Haller),the largest branch of the internal iliac, is distributed to the muscles on the outside of the pelvis.

The vessel which supplies the lower extremity forms a continuous trunk from the point of division of the common iliac artery down to the lower border of the popliteus muscle, where it divides into the anterior and posterior tibial arteries ; but though thus continued as a single trunk different parts of the vessel have received different names, taken from the anatomical regions through which they pass. Whilst within the pelvis, it is named iliac; in the upper two-thirds of the thigh, femoral ; and thence to its termination, popliteal. These divisions, however, are artificial, and are intended merely to facilitate reference to the vessel in different situations.

The sciatic or ischiatic artery, [a. ischiadica], the largest branch of the internal iliac artery, excepting the gluteal, is distributed to the muscles on the back of the pelvis.

The lateral sacral arteries, [a. sacrales laterales], which are usually two in number on each side, occasionally but one, arise close together from the posterior division of the internal iliac artery.

Before escaping from the pelvis, the pudic artery occasionally gives small and irregular branches to the muscles and to the sacral nerves : and, besides its two terminal branches, it furnishes several named branches in the perineum.

The ilio-lumbar artery (ilio-lumbalis, — Haller), resembles in a great measure the lumbar arteries.

The pudic or internal pudic artery (pudica interna; pudica communis,— Winslow ; pudenda (simpliciter),— Haller), a branch of considerable size (smaller in the female than in the male), is distributed to the external generative organs. The following description of this artery has reference to its arrangement in the male;— its distribution in the female will be noticed separately.
