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
Fasciae are layers of connective tissue, mainly collagen, situated under the skin, which closes, supports, and separates muscles and other structures. Fasciae are grouped by their anatomical location, layer (as visceral fascia, superficial fascia, and deep fascia), or by their functions. Fasciae reduces friction and provide an adjustable covering for nerves and blood vessels as they move through muscles.
