The other answer choices:
motor innervation to the bulbocavernosus muscle = deep/muscular branch of the perineal nerve, which is branch of the pudendal nerve
motor innervation to the lower portion of the rectus abdominis muscle = thoraco-abdominal nerves, which are continuations of the T7-T11 intercostal nerves
sensation from the dorsal surface of the penis = dorsal nerve of the penis, which is the deepest division of the pudendal nerve
It is the ILIOINGUINALguys stop misleading ppl! https://www.openanesthesia.org/aba_ilioinguinal_anatomy/
Just to clarify all the comments.
(B) Rectus innervation would not be as deep as the spermatic cord (thoracoabdominal/intercostal nerves)
(A) & (D) are both pudendal nerve, I think it's reasonable to exclude both as an answer choice as such
(C) Process of elimination. Sure, we can nitpick if it's genitofemoral or ilioinguinal but I think that's all we're being tested on here
after rabbit-holing this one for a bit.... this is the photo that demonstrates it best (to me, anyway). must be ilioinguinal n.
The pampiniform plexus, testicular artery, cremasteric artery, artery of the ductus deferens, lymphatic vessels, testicular sympathetic nerves, and ductus deferens all run deep to the internal spermatic fascia. The ilioinguinal nerve runs on the superficial surface of the external spermatic fascia The ilioinguinal nerve is a sensory nerve that innervates the skin over the groin region, the medial aspect of the thigh, the upper part of the scrotum and the penile root. It is normally encountered during open repair of inguinal hernia.
It appears that both the genitofemoral nerve (genital branch) and the ilioinguinal nerve both are external to the spermatic cord and at the superficial inquinal canal. Depending on location of the genitofermal nerve makes a difference for what it innervates. It appears that the genitofemoral nerve (genital branch) innervates the lateral anterior surface of the srotum, while the ilioinguinal nerve innervates the anterior surface of the scrotum.
Google also says that the genital branch of the genitofemoral nerve can innervate the sensation of the skin of the anterior surface of the scrotum. Does it appears that either nerve choice would lead you to the correct answer?
The question asks about a nerve that is on the EXTERNAL surface of the espermatic cord at the level of superficial ring, that is the ilioinguinal nerve, because the genital branch of the genitofemoral nerve goes inside.
The trick is that the genitofemoral is responsible of invervating the anterior surface of the escrotum, but the genital branch of the inguinal nerve that goes external is responsible of the superior anterior surface of the scrotum
Here you can see both nerves outside and inside the spermatic cord https://image.slidesharecdn.com/herniasdepared-170305224216/95/hernias-de-pared-10-638.jpg?cb=1488753771 and here you can see the inervation from both nerves https://medicalfoster.com/wp-content/uploads/2017/01/attelu-rezultati-vaicajumam-genitofemoral-nerve.jpeg
