2 Biomechanics

Question 1

Biomechanics

Answer 1

focuses on the mechanisms through which the musculoskeletal compo- nents interact to create movement.

Question 2

the muscle’s origin

Answer 2

proximal (toward the center of the body) attachment

Question 3

The muscle’s insertion

Answer 3

distal (away from the center of the body) attachment.

Question 4

fleshy attachments

Answer 4

are most often found at the proximal end of a muscle, muscle fibers are directly affixed to the bone, usually over a wide area so that force is distributed rather than localized.

Question 5

Fibrous attach- ments, such as tendons,

Answer 5

blend into and are continuous with both the muscle sheaths and the connective tissue surrounding the bone.

Question 6

muscle most directly involved in bringing about a movement is called the prime mover

Answer 6

Agonist

Question 7

muscle that can slow down or stop the movement is called

Answer 7

The antagonist

Question 8

muscle is called a ________ when it assists indi- rectly in a movement
