Q

The [structure] is the abrupt termination of the posterior rectus sheath

A

The arcuate line​ is the abrupt termination of the posterior rectus sheath

Below this line, the rectus abdominus lies directly on transversalis fascia

Q

The [layer of the body wall] contributes to the external spermatic fascia and superficial inguinal ring

A

The external oblique contributes to the external spermatic fascia and superficial inguinal ring

18
