The external spermatic or cremasteric artery (A. spermatica externa) is a very small vessel which arises in a variable manner. It springs most often from the external iliac near the origin of the latter, but may come from the circumflex iliac, the aorta between the external and internal iliac, or the latter vessel. It accom- panies the cremaster muscle to the inguinal canal, supplies twigs to that muscle, the tunica vaginalis, and other constituents of the spermatic cord (Fig. 575). 2a. The middle uterine artery (A. uterina media) of the female is regarded as the homologue of the preceding vessel; it has a similar origin, but is a much larger artery. It enters the broad ligament of the uterus, in which it pursues a flexuous course to the posterior part of the horn of the uterus. Its branches are distributed to the uterus and anastomose with those of the other uterine arteries. The Femoral Artery (Figs. 575, 576) The femoral artery is the main arterial trunk of the thigh. It begins at the level of the anterior border of the pubis, from which it is separated by the femoral

The testicle (on the right side) has been rotated somewhat to show the cremaster muscle, (.\fter Schmaltz, Atlas d. Anat. d. Pferdes.) vein. It descends almost vertically in the femoral canal behind the sartorius muscle, covered at first by the medial femoral fascia and lower down by the gracilis. After passing over the insertion of the pectineus, it perforates the adductor muscle, crosses in the vascular groove of the posterior surface of the femur, and is continued
