:'''Insertion''': Entire medial aspect of the femur, from the lesser trochanter to the medial condyles, and the medial collateral stifle ligament.

:'''Action''': Adduct the limb, can also retract the limb and move the rump forward and sideways

===Inner Pelvic Muscles===
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'''''
'''''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
