Anatomy

Step 1: Understanding the muscles and their innervations.
The muscles in the gluteal region and their innervations play a crucial role in movement and stability. Each muscle is innervated by specific nerves that facilitate their function.
Step 2: Analyzing each muscle and its nerve supply.
- (A) Gluteus maximus: It is innervated by the Inferior gluteal nerve (IV).
- (B) Piriformis: It is innervated by the Nerve to quadratus femoris (II).
- (C) Gemellus inferior: It is innervated by the Ventral rami of S1 and S2 (I).
- (D) Gluteus minimus: It is innervated by the Superior Gluteal nerve (III).
Step 3: Conclusion.
The correct matching is: (A) - (III), (B) - (II), (C) - (IV), (D) - (I).
