Dissection of male inguinal region and spermatic cord Falx inguinalis (continued); transversalis fascia The spermatic cord (10) has been elevated from its normal position within the inguinal canal. All fascicles of the internal oblique muscle have been cut off, whereas the underlying transversus muscle has been kept intact. The transversalis fascia (9) and interfoveolar ligament (14) are visible in the depths of the dissection. These structures are exposed more completely in the following view (136-4). 1 . Internal oblique muscle (lower part of origin) 2 . Internal oblique muscle (divided near insertion into sheath of rectus) 3 . Thoracic nerve XII (entering sheath of rectus) 4 . Sheath of rectus abdominis muscle 5 . Aponeurosis external oblique muscle (reflected medially) 6 . Conjoint tendon 7 . Reflected inguinal ligament (lower pointer indicates location of pubic tubercle) 8 . Transversus abdominis muscle (pointer near lower border of muscle) 9 . Transversalis fascia 10 . Spermatic cord (covered by internal spermatic fascia) 11 . Cremaster muscle 12 . Internal oblique muscle (lower part of muscle which joins transversus to form conjoint tendon) 13 . Aponeurosis external oblique muscle (reflected to expose internal aspect of inguinal ligament) 14 . Interfoveolar ligament (muscle fibers present, a few of which enter cremasteric layer)
