Which of the following is not a content of adductor canal?
**Core Concept**
The adductor canal, also known as Hunter's canal, is a fascial canal in the middle third of the thigh. It contains the femoral artery, femoral vein, and saphenous nerve. The canal is located between the aponeuroses of the sartorius and vastus medialis muscles.
**Why the Correct Answer is Right**
The contents of the adductor canal are primarily related to the structures that pass through it, including the femoral artery and vein, which are responsible for providing blood supply to the lower limb. The saphenous nerve, a branch of the femoral nerve, also passes through the canal, providing sensory innervation to the medial aspect of the leg.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is not a content of the adductor canal, as it is actually located outside the canal. The femoral nerve does not pass through the adductor canal, but rather lies lateral to it, innervating the quadriceps and iliopsoas muscles.
**Option B:** The femoral artery and vein are indeed contents of the adductor canal, making this option incorrect.
**Option C:** The saphenous nerve is a content of the adductor canal, so this option is also incorrect.
**Clinical Pearl / High-Yield Fact**
The adductor canal is a critical anatomical landmark in the thigh, and its contents are essential for understanding the vascular and nervous supply of the lower limb.
**Correct Answer:** A. The femoral nerve is not a content of the adductor canal.
