Dissection of male inguinal region and spermatic cord
Internal oblique and transversus muscles; falx inguinalis
Several fascicles of the internal oblique have been elevated (4) to reveal the underlying fascia and transversus muscle. The lower borders of the internal oblique and transversus blend in this specimen into a tenuous conjoined muscle (6). As is frequently the case, a definite conjoint tendon is not present and the lower parts of the muscles are not readily distinguished.
