The inner pelvic muscles are small and lie close to the coxofemoral (hip) joint. They run between the pelvis and trochanteric fossa of the femur.
Internal Obturator
- In the horse this muscle has two heads, a small and tendinous pubic head and a larger pelvic head.
- Innervation: Sciatic n.
- Origin:
- Pubic head - Cranial and medial borders of the obturator foramen
- Pelvic head - Pelvic symphysis and pelvic aspect of the body of the ilium
- Insertion: Trochanteric fossa together with the gemellus muscle, having passed over the lesser sciatic notch
- Action: Rotates the femur laterally, aids hip extension
External Obturator
- Innervation: Obturator n.
- Origin: Vental surface of pelvis, close to the obturator foramen
- Insertion: Trochanteric fossa
- Action: Supinates the femur and adducts the limb
Gemellus
- In the horse, these two small muscle bundles are fused and unite partly with the internal obturator muscle
- Innervation: Sciatic n.
- Origin: Ischium
- Insertion: Trochanteric fossa
- Action: Aids lateral rotation of the limb
