Human body has more than ____ skeletal muscles, which account for almost ___ of the body's weights

Voluntary muscles

a person can consciously choose to contract a muscle, and for how long and hard to contract them.

arms and legs are an example

Involuntary muscles

muscles under the control of subconscious regions of the brain.

Found in internal organs and cardiac muscles.

SKELETAL

CARDIAC

SMOOTH

three types of muscles:

Skeletal Muscle

• directly or indirectly attached to the bone

• produces VOLUNTARY movement

• Striated muscle. (because its striped)

Fascia

a fibrous connective tissue that wraps each muscle.

helps form a very strong tendon

Motor neurons

makes skeletal muscles stimulated, coming from the nervous system.

Myoneural Junction

When a motor nerve contacts a muscle fiber, this happens.

Smooth muscles

found in associaton with internal organs

referred to as Visceral muscle

has a microscopic appearance, and lacks striations

Found in walls of hollow organs, and responsible for involuntary muscle action

Visceral muscle

another name for smooth muscle

Cardiac muscle

or myocardium

makes up the wall of the HEART

each involuntary contraction makes the heart squeeze, to pump out blood
