Anatomy Practical

Question 1

Tissue levels from scrotum to artery/vein/nerves of testicles

Answer 1

Scrotum –> Dartos fascia –> external spermatic fascia –> Cremaster muscle/fascia –> Internal spermatic fascia

Question 2

Pudendal nerve origin and travel

Answer 2

Originates S2-S4

Travels out greater sciatic notch superior to piriformis –> back through lesser sciatic notch –> Enters pudendal canal

Question 3

Pudendal nerve brances

Answer 3

Inferior rectal nerve

Perineal nerve

Dorsal nerve of penis/clitoris

Question 4

Inferior rectal nerve

Answer 4

Arises from pudendal nerve

Supplies sympathetic innervation to rectum inferior to pectinate line

Pain sensations associated with external hemorrhoids

Question 5

Perineal nerve

Answer 5

Divides into superficial branch and deep branch

Superficial branch supplies innervation to posterior scrotal and labia majora

Deep branch provides innervation to muscles of perineum - ischiocavernosus, bulbospongiosum, levator ani

Question 6

Pelvic splanchnic nerves

Answer 6

Parasympathetic nerves arising from ventral rami of S2-S4

Join in with inferior hypogastric plexus

Innervate pelvic viscera: Bladder control, rectum (above pectinate line), erection, internal urethral sphincter

Question 7

Obturator artery

Answer 7

Arises from internal iliac artery

Exits pelvis via obturator canal

Supplies obturator internus muscle and part of thiggh
