Muscles 8D TA 2023 2024 SMP ND

State the names of the parts indicated by parts X and Y!

• X : Triceps and Y : Biceps

• X : Biceps and Y : Triceps

Compare the diameter of the muscles when the hand is straightened and bent? Which diameter is longer?

• When bent, the diameter is longer because there is a contraction of the biceps

• When bent, the diameter is longer because there is a contraction of the triceps

• When straightened, the diameter is longer because there is a contraction of the biceps

• When straightened, the diameter is longer because there is a contraction of the triceps

When the arm is bent, what muscles contract and what muscles relax?

• When bent: the biceps contract and the triceps relax

• When bent: the triceps contract and biceps relax

Synergistic muscle work is two muscles that work together in the same direction where these muscles contract and relax simultaneously. In an antagonistic muscle pair as one muscle contracts the other muscle relaxes or lengthens. How do the biceps and triceps work?

• antagonist's muscles

• Synergistic muscle

Pay attention to the following picture!

• (1) Cardiac muscle, (2) Skeletal muscle and (3) Smooth muscle  

• (1) Skeletal muscle, (2)  Smooth muscle and (3) Cardiac muscle    

• (1) Smooth muscle, (2) Skeletal muscle and (3) Cardiac muscle    

• (1) Smooth muscle, (2) Cardiac muscle and (3) Skeletal muscle 

Pay attention to the characteristics of smooth muscle, skeletal muscle and cardiac muscle! Is it already correct ?

• Yes
