The dissector's guide, or, Student's companion : illustrated by numerous woodcuts, clearly exhibiting and explaining the dissection of every part of the human body . res of the posteriorlayer are to be found behind the rectus ; the principal part of it passingbefore that muscle, with the tendon of the transversahs, to be insertedinto the cartilages of all the false ribs, into the ensiform cartilage, andwhole length of the linea alba. Action, — to assist the former bends the body, however, in the same direction with the obliquusexternus of the opposite side. The cremaster, vel musculus testis, arises from the inferior edge of theobliquus internus abdominis ; passing through the ring of the obliquusexternus, it surrounds the spermatic cord as far as the testicle, where thefibres separate and expand, to be inserted into the tunica vaginalis testis,and cellular substance of the scrotum. Action, — to suspend, elevate,compress, and evacuate the testicle. The sheath of the internal oblique may now be reflectedon one side, and the muscular fibres on the opposite side,which will bring into view the remaining muscles. THE DISSECTORS GUIDE. 141. g. The obliquus interims, with its tendon divided, to show h. The pyramidalis. i. The rectus abdominis. Beneath the internal oblique there is situated k. The transversalis abdominalis, and I. The fascia transversalis. h. The pyramidalis arises by a broad base, from the upper part of thesymphysis pubis. It runs upwards within the same sheath with the rec-tus, tapering to a point in its ascent, to be inserted near half way betweenthe pubis and umbilicus, in the linea alba and inner edge of the , — to assist the under part of the rectus in drawing down the ribs,or to compress the under part of the abdomen. It is frequently wantingin both sides, and then the under end of the rectus is larger, thus insome measure supplying its place. i. The rectus abdominis arises from the fore and upper part of thesymphysis pub
