1. which motion turns the palm of the hand downward or backward?

a. abduction c. pronation
b. adduction d. supination

Explanation:

1. True. Skeletal muscles have a striped appearance and are called striated muscles.
2. True. Fasciitis is indeed inflammation of the fascia.
3. False. Insertion is where a muscle attaches to a more movable bone, not just where it ends. The correct statement: Insertion is the attachment of a muscle to a more movable bone at a joint.
4. True. A leiomyoma is a benign tumor of smooth - muscle.
5. True. Hyperkinesia is abnormally increased muscle function or activity.
6. False. A rotator cuff injury affects the shoulder, not the knee. The correct statement: A rotator cuff injury affects the shoulder.
7. False. A sprain is an injury to a ligament, not the body of a muscle or tendon attachment. The correct statement: A sprain is an injury to a ligament.
8. False. Myorrhaphy is the suture of a muscle, not its rupture. The correct statement: Myorrhaphy is the surgical suture of a muscle.
9. True. Fascia is the sheet of fibrous connective tissue that covers, supports, and separates muscles or groups of muscles.
10. True. Smooth muscles are located in the walls of internal organs such as the digestive tract, blood vessels, and ducts leading from glands.
11. The point at which a muscle begins is known as the origin. So the answer is b.
12. The term "oblique" in a muscle name means slanted or at an angle. So the answer is b.
13. The term "flexion" means to bend a limb at the joint. So the answer is d.
14. Pronation turns the palm of the hand downward or backward. So the answer is c.
