-Soleus
-Tibialis anterior

-Tibia
-Fibula tarsals
-Metatarsals
-Phalanges

Question 13

Muscles and bones (wrist and hand region)

Answer 13

-No muscles

-Radius
-Ulna
-Carpals
-Metacarpals
-Phalanges

Question 14

Isometric contraction

Answer 14

Means the muscle stays the same length.
Ex, holding a weight in a static position.
Length of the muscle doesn’t change but amount of tension increases.

Question 15

Isotonic contraction - concentric

Answer 15

muscle shortening under tension.
Ex, when jumping after a squat, quadriceps shortens to allow extension of the knee joint.

Question 16

Isotonic contraction - eccentric

Answer 16

Involves a muscle lengthening under tension.
Ex, when doing a squat the quadriceps lengthens under tension.

Question 17

Synergist muscles

Answer 17

Assists the agonist muscle “primary mover” for a specific action at a joint.
Is not the main muscle involved in the action, but works in synergy with the primary muscle, helps make movements more accurate and fluid.

Ex, gastrocnemius and soleus in a dorsi flexión.

Question 18

Fixator muscle

Answer 18

A muscle which acts as the stabilizer of one part of the body during movement of another part. Allowing agonist muscle to work effectively.

Ex, deltoid helps stabilize the biceps during biceps curl.
