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

A. Sciatic nerve
B. Lateral sacral branch of the posterior division of the internal iliac artery
C. Obturator nerve
D. Common fibular nerve

**Core Concept:** The adductors of the thigh are a group of muscles that help in keeping the thigh close to the midline of the body. They are innervated by specific nerves.

**Why the Correct Answer is Right:**
The correct answer is C. Obturator nerve, as the obturator nerve is the primary source of innervation for the adductor muscles of the thigh. These muscles include the adductor longus, adductor brevis, and adductor magnus. The obturator nerve arises from the ventral rami of the L2-L5 spinal nerves and passes through the obturator canal before supplying the adductor muscles.

**Why Each Wrong Option is Incorrect:**
A. Sciatic nerve: The sciatic nerve supplies the gluteal muscles, not the adductor muscles of the thigh.
B. Lateral sacral branch of the posterior division of the internal iliac artery: This option is incorrect as the adductor muscles are supplied by the obturator nerve, not the lateral sacral branch.
D. Common fibular nerve: The common fibular nerve supplies the muscles of the posterior compartment of the thigh, not the adductor muscles.

**Clinical Pearl:**
Understanding the anatomy of the nerves supplying muscles is crucial for clinical practice, as it helps in diagnosing and treating musculoskeletal injuries and conditions. For example, if a patient complains of adductor weakness, a neurologist might consider assessing the obturator nerve for compression or injury, as damage to this nerve could be a cause of adductor muscle weakness.
