Muscle tissue, which comprises about
40% of the human body weight,
consist of threads, or muscle fibers,
supported by connective tissue.
2 Types of the structure of muscle
Smooth or “ Involuntary” muscles
-are found in the walls of all the hollow organs and tubes
of the body.
Striated or “voluntary” muscles
-the body are attached mostly to the bones to move the
skeleton. These muscles are capable of fast contraction.
FUNCTION OF MUSCLE
Skeletal muscles perform a variety of different function, all which
are important to efficient performance of human body.
3 functions relating specifically to
a. Contributing to skeletal movement
b. Assisting in joint stability
c. Maintaining posture and body positioning
Skeletal movement is created as muscle actions generate
tensions that are transferred to the bone.
Maintain Postures and Position
Muscle action a lesser magnitude are utilized to maintain
Muscle actions also contribute significantly to the
stability of the joints.
The skeletal muscle also provide four other function that are not
directly related to human movement.
First, muscles support and protect the visceral organs and protect the internal tissues
Second, tension in the muscle tissue can alter and control pressures within the cavities.
Third, the skeletal muscles also contribute to the maintenance of the body temperature by
