Question 1

Origin

Answer 1

attachment to the immovable or less movable bones

Question 2

Insertion

Answer 2

the attachment to the movable bones

Question 3

Flexion

Answer 3

a movement that decreases the angle of the joint and brings two bones close together (bending the knee)

Question 4

Extension

Answer 4

opposition of flexion; movement that increased the angle or distance between two bones or part of the body (straightening the knee)

Question 5

Rotation

Answer 5

the movement of a bone around its longitudinal axis (shaking the head no)

Question 6

Abduction

Answer 6

the movement of a limb AWAY from the midline of the body (moving the leg laterally from the body)

Question 7

Adduction

Answer 7

opposite of abduction; the movement of a limb toward the midline of the body (moving leg medially toward the body)

Question 8

Circumduction

Answer 8

movement of a limb or extermityt so that the distal end describes a circle while the proximal end remains fixed

Question 9

dorsiflexion

Answer 9

lifting the foot so that its superior surface approaches the shin (standing on heels)

Question 10

plantar flexion

Answer 10

depressing the foot (pointing the toes downward)

Question 11

inversion

Answer 11

turning of the sole medially (ankle inward)

Question 12

eversion

Answer 12

turning of the sole laterally (ankle outward)

Question 13

Supination

Answer 13

movement of the forearm that rotates laterally so that palms face forward

Question 14

pronation

Answer 14

movement that occurs in the forearm and rotates medially so that palms face posterially and ulna and radius form an x

Question 15

opposition

Answer 15

action of saddle joint between metacarpal 1 and the carpals (thumb touches other points of fingers)

Question 16

prime mover

Answer 16

(agonist) muscle that has the major responsibility for causing a particular movement

Question 17

antagonist

Answer 17

muscles that move opposite or reverse a movement (stretched and relaxed when agonist is active)

Question 18

synerngists

Answer 18

help prime movers by producing the same movement

Question 19

fixators

Answer 19

specialized synergist; hold bones still or stabilize the origin of a prime mover so all the tension can be used to move the insertion bone
