The correct answer is muscles can only pull.

The movement of arm takes place by the relaxation and contraction of muscles. Muscles in animals are in pair because muscles can only pull, when a pair of muscle is present in animals one muscle relaxes and the other one contracts. An example of this is biceps and triceps of arm. The triceps  of the arm relaxes while the biceps of the arm  contracts, this movement helps to lift the arm. The reverse also takes place in the arm.

guajiro [1.7K]

Answer:

Option C

Explanation:

Gastrocnemius and soleus muscles are jointly known as calf. Gastrocnemius is the larger muscle and connects to the knee joint while soleus is smaller muscle that connects to the portion of leg just below the knee. When gastrocnemius is stretched, the knee remains straight while when the soleus is stretched the knee bends. If a person feels difficulty in bending or stretching the knees, he/she must be facing the problem with the calf muscle. Hence, Option C is correct
