The transversus muscle is separated by the lower intercostal nerves from the obliquus internus muscle, and is lined on its deep surface by the fascia transversalis. Its inferior border forms a concave edge, separated from the inguinal ligament by a lunular interval in which the fascia transversalis appears, and through which the spermatic funiculus emerges at the abdominal inguinal ring, under cover of the obliquus internus muscle and the aponeurosis of the obliquus externus.

M. Pyramidalis Abdominis. â The pyramidalis abdominis is a small triangular muscle arising from the pubic crest, anterior to the rectus muscle (Fig. 428, p. 482). It is directed obliquely upwards, to be inserted for a variable distance into the linea alba. The muscle is often absent. M. Rectus Abdominis.âThe rectus abdominis muscle is broad and strap- like, and arises, by a medial and a lateral head, from the symphysis and crest of the pubis (Fig. 428, p. 482). Expanding as it passes upwards, the muscle is inserted, from medial to lateral side into the anterior surface of
