1

The action of certain muscles in pulling a leg, arm, etc away from the median axis of the body.

Abduction

2

A globulin that is present in muscle plasma and that in connection with myosin plays an important role in muscle contraction.

Actin

3

 To draw or pull (a leg, arm, etc) towards the median axis of the body.
 

Adduction

4

Characterized by either a complete response or by a total lack of response or effect, depending on the strength of the stimulus.

All or none response

5

A muscle that acts in opposition to another.

Antagonist

6

A wasting away of an organ or part, or a failure to grow to normal size as the result of disease, faulty nutrition, etc

Atrophy

7

A pouch, sac, or vesicle, especially a sac containing synovia, to facilitate motion, as between a tendon and a bone.

Bursa

8

Movement of a part in a circular direction.

Circumduction

9

Flexion towards the back.

Dorsiflexion

10

 A pulling or dragging force exerted on a limb in a distal direction.

Extension

11

A turning or being turned outward or inside out.

Eversion

12

Physical or mental weariness resulting from exertion.

Fatigue

13

The act of bending a joint or limb.

Flexion

14

An  abnormal enlargement of a part or organ; excessive growth.

Hypertrophy

15

 Abnormally low body temperature.

Hypothermia

16

The insertion of the bone is the end of the bone attaching to  a  joint.

Insertion bone

17

 Located or occurring between the ribs.

Intercostal

18

 The act of inverting or the state of being inverted.

Inversion

19

Acting independently of or done or occurring without volition: involuntary muscles.

Involuntary

20

An increase in muscular tension without a change in muscle length.

Isometric contraction

21

When a muscle becomes longer or shorter to produce force.

Isotonic Contraction

22

 A neuron that conveys impulses from the central nervous system to a muscle, gland, or other effector tissue.

Motor neuron

23

 A single somatic motor neuron and the group of muscle fibers innervated by it.

 

 

 

Motor unit

24

 Any of the ultramicroscopic filaments, made up of actin and myosin, that are the structural units of a myofibril.

Myofilaments

25

The principal contractile protein of muscle.

Myosin

26

The junction between a nerve fiber and the muscle it supplies.

Neuromuscular junction

27

Not striated; unstriped, as certain muscular tissue.

Non-striated

28

the beginning, starting-point, cause, or ultimate source of a bone.

Origin bone

29

The amount of extra oxygen required by muscle tissue to oxidize lactic acid and replenish depleted ATP and phosphocreatine following vigorous exercise.

Oxygen debt

30

Loss or impairment of voluntary movement or sensation in a part of the body, usually as a result of neurologic injury or disease. 

Paralysis
