is stabilized by very
strong ligaments & a
joint capsule.
Muscles
 Muscles of the

muscles are the
Hamstring Muscle
Group. The
Hamstrings are the
Biceps Femoris, the
Semitendinosis, & the
Semimembranosis.

 The muscles of the
medial thigh are
known as the
Adductor Group. The
muscles of this group
are the Gracilis,
Pectineus, Adductor
Magnus, Adductor
Longus & the
