2. Introduction Appendicular Musculature
Muscles that are responsible for stabilizing the pectoral and pelvic girdles and for moving the upper and lower limbs

3. Introduction Appendicular Muscles
Account for roughly 40 percent of the skeletal muscles in the body
Two major groups of appendicular muscles:
The muscles of the pectoral girdle and upper limbs
The muscles of the pelvic girdle and lower limbs
The functions and required ranges of motion differ greatly between these groups.

4. Factors Affecting Appendicular Muscle Function
Muscles of the appendicular skeleton may cross one or more joints between its origin and insertion.
The position of the muscle as it crosses a joint helps determine the action of that muscle.
Complex actions often involve more than one joint of appendicular skeleton.
Muscles that cross only one joint typically act as prime movers; muscles that cross more than one joint typically act as synergists.

6. Muscles of the Pectoral Girdle and Upper Limbs
Muscles associated with the pectoral girdle and upper limbs can be divided into four groups:
Muscles that position the pectoral girdle
Muscles that move the arm
Muscles that move the forearm and hand
Muscles that move the hand and fingers

34. Muscles of the Pelvic Girdle and Lower Limbs
The muscles of the lower limbs are larger and more powerful than those of the upper limbs.
These muscles can be divided into three groups:
Muscles that move the thigh
Muscles that move the leg
Muscles that move the foot and toes

66. Fascia, Muscle Layers, and Compartments
Dense connective tissue layers provide a structural framework for the soft tissues of the body.
The connective tissue fibers of the deep fasciae support and interconnect adjacent skeletal muscles but permit independent movement.
The deep fascia extends between the bones and the superficial fascia and separates the soft tissues of the limb into separate compartments.
