Name:
Muscles of the Hip and Lower Limb
Laboratory Exercise 23
Background
The muscles that move the thigh are attached to the femur and to some part of the
pelvic girdle. Those attached anteriorly primarily act to flex the thigh at the hip,
whereas those attached posteriorly act to extend, abduct, or rotate the thigh.
The muscles that move the leg connect the tibia or fibula to the femur or to the pelvic
girdle. They function to flex or extend the leg at the knee. Other muscles, located in
the leg, act to move the foot.
Materials Needed
Textbook
Articulated skeleton
Muscular model of the lower limb
Purpose of the Exercise
Review the actions, origins, and insertions of the muscles
that move the thigh, leg, and foot.
Procedure
1. Label figures 23.1, 23.2, 23.3, 23.4, 23.5, and 23.6.
2. Try to locate the muscles, labeled in the diagrams,
in your own body:
3. Demonstrate the action of these muscles in your
own body.
4. Locate the origins and insertions of these muscles
in the human skeleton.
5. Complete Parts A, and B.
Figure 23.1 Label the muscles of the anterior right hip and thigh.
Figure 23.2 Label the muscles of the lateral right hip and thigh.
Figure 23.3 Label the muscles of the posterior right hip and thigh.
Figure 23.4 Label the muscles of the anterior right leg.
Figure 23.5 Label the muscles of the lateral right leg.
Figure 23.6 Label the muscles of the posterior right leg.
