| − | 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
