Question

Arm and leg muscles are arranged in antagonistic pairs. How does this affect their functioning
a) it provides a backup if one of the muscles is injured
b) one muscle of the pair pushes while the other pulls
c) it allows the muscles to produce opposing movements
d) it doubles the strength of contraction​

Answer 1

Answer:

C

Explanation:

it allows the muscle to produce opposing movements.Muscle A and Muscle B are the same size but muscle A is capable of much finer control than muscle B

Answer 2

The answer will be the arrangement of the arm and leg muscles in antagonistic pairs help in functioning because c) it allows the muscles to produce opposing movements.

• The term antagonistic in terms of biology means that certain things are arranged oppositely, i. e. two objects used for the same function are arranged opposite to each other.
• In the given question, it is stated that the arm and leg muscles are arranged in antagonistic pairs.
• This means that one of the muscles is present opposite to the primary functioning muscle (depending on the type of movement, can be either leg or arm muscle).
• The placement of the muscles in antagonistic pairs helps the muscles in opposing each other's movements and therefore, produce opposing movements that help in locomotion.

Hence, the correct option that showcases the functioning of the arm and leg muscles that are arranged in antagonistic pairs will be c) it allows the muscles to produce opposing movements.
