Question 1

During a carotid endarterectomy, injury to which nerve results in hoarseness and difficulty swallowing?

Accepted Answer

Recurrent laryngeal nerve

Answer

The recurrent laryngeal nerve innervates the intrinsic laryngeal muscles, and injury causes ipsilateral vocal cord paralysis with hoarseness.

Question 2

The arcuate line (linea semicircularis) of the rectus sheath is significant because below it:

Accepted Answer

The posterior wall of the rectus sheath is absent

Answer

Below the arcuate line, all aponeurotic layers pass anterior to the rectus abdominis, leaving the posterior wall formed only by transversalis fascia.

Question 3

Which ligament of the knee contains the blood supply to the anterior cruciate ligament (ACL) and must be respected during arthroscopic ACL reconstruction?

Accepted Answer

Middle geniculate artery via the synovial sheath

Answer

The ACL receives its blood supply primarily from the middle geniculate artery through the synovial sheath surrounding it.

Question 4

During open Roux-en-Y gastric bypass, the Roux limb must pass through which anatomical route to reach the gastric pouch?

Accepted Answer

Antecolic, antegastric route

Answer

The antecolic, antegastric route is preferred in most laparoscopic gastric bypass procedures as it avoids internal hernias through the mesocolon.

Question 5

The pudendal nerve (S2-S4) exits the pelvis through the greater sciatic foramen and re-enters through the lesser sciatic foramen to travel in which canal?

Accepted Answer

Alcock's canal

Answer

The pudendal nerve travels through Alcock's canal (pudendal canal) along the lateral wall of the ischioanal fossa after re-entering through the lesser sciatic foramen.
