Anatomy Muscle system

1. the protein contained in red blood cells that is responsible for delivery of oxygen to the unit: a single motoneuron and the many muscle fibers to which its axon runs.
7. the contracting tension in the muscle remains constant in a steady state.
9. a muscle whose contraction bends a limb or other part of the body
12. occurs when one muscle fiber contracts in response to a command by the nervous system.
13. the delay between the receipt of a stimulus by a sensory nerve and the response to it.
15. the involuntary constriction and relaxation of the muscles of the intestine or another canal,intercalated discs
17. any of the muscles that increase the angle between members of a limb
18. a superficial extensor muscle located in the posterior compartment of the brachii: a large, thick muscle on the ventral portion of the upper arm.
19. the amount of tension (or resistance to movement) in muscles.

2. a protein located primarily in the striated muscles of vertebrates
3. a temporary oxygen shortage in the body tissues arising from exercise
4. any of the muscles that cause movement of a limb away from the midplane of the body or away from a neighbouring part or limb
5. mainly produced in muscle cells and red blood cells
6. attached at the front, side, and rear of the shoulder
8. major: the superior most and largest muscle of the anterior chest wall
10. the additive effect of several electrical impulses on a neuromuscular junction
11. a muscle whose contraction causes or assists in the rotation of a part of the body.
14. the source of energy for use and storage at the cellular level
16. each of a pair of long muscles that connect the sternum, clavicle, and mastoid process of the temporal bone and serve to turn and nod the l oblique: located on the outer surface of the sides of the abdomen, on each side of the rectus abdominis.
