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

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.

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.

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

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

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.
