**Question:** Nerve supply of adductors of thigh includes

* A. Sciatic nerve
* B. Sural nerve
* C. Obturator nerve
* D. Lateral femoral cutaneous nerve

**Core Concept:**

The adductors of the thigh are a group of muscles that help to bring the thigh towards the midline of the body. These muscles are innervated by specific nerves, which supply them with motor neurons.

**Why the Correct Answer is Right:**

The correct answer, C. Obturator nerve, is responsible for supplying the motor neurons to the adductor muscles of the thigh. The obturator nerve is a mixed nerve, containing both sensory and motor components. It arises from the ventral rami of the lower five lumbar and all five sacral spinal nerves. The adductor muscles are part of the motor division of the obturator nerve, which means they receive motor supply from this nerve.

**Why Each Wrong Option is Incorrect:**

A. The sciatic nerve is incorrect because it supplies the muscles of the posterior compartment of the thigh, not the adductors. The adductors are innervated by the obturator nerve.

B. The sural nerve is incorrect as it is a sensory nerve that supplies the skin of the lateral calf and heel, not the adductor muscles.

D. The lateral femoral cutaneous nerve is a sensory nerve that supplies sensation to the lateral aspect of the thigh and knee, not the adductor muscles.

**Clinical Pearl:**

Understanding the correct innervation of muscles is essential for understanding muscle function, injury, and rehabilitation. In a clinical scenario, an injury to the obturator nerve might lead to adductor weakness, which is crucial for identifying potential nerve damage and planning appropriate treatment strategies.
