100

Muscle tone

The state of partial contraction at all times, even when not in use.

Adduction 

moving a body part toward the midline

Muscle that is attached to bones and causes body movement; it is voluntary 

300

Cardiac Muscle

forms the wall of the heart and contracts to circulate blood; it is involuntary 

300

Elasticity

Allows the muscle to return to its original shape after it has contracted or streched

300

Flexion

Decreasing the angle between 2 bones or bending a body part

300

Origin

The end of the muscle that does not move when the muscle contracts

300

Suspination

turning a body part upward
400

Circumduction

Moving in a circle at a joint or moving one end of a body part in a circle while the other end remains stationary

400

Excitability

The ability to respond to a stimulus such as a nerve impusle

400

Insertion

The end of muscle that moves when the muscle contracts

400

Plantar flexion

bending forward or bending the foot away from the knee

400

Tendons

Strong tough fibrous connective tissues cords that attach muscles to bones
500

Contractibility

The ability of muscle fibers that are stimulated by nerves to contract or become short and thick which causes movement 

500

Extebsibility

The ability to be streched

500

Involuntary

Functions without conscious thought or control

500

Pronation

Turing a body part downward
