Sura

From WikiMD's Wellness Encyclopedia

Sura is a term used in Anatomy and Zoology, referring to the calf of the leg. The term is derived from the Latin word "sura", meaning calf. In humans, the sura is located between the knee and the ankle. It is the area of the lower leg that is posterior to the tibia and fibula, the two bones of the lower leg. The muscles of the sura, the gastrocnemius and soleus, are responsible for the movement of the foot and ankle.

Anatomy[edit | edit source]

The sura is made up of two muscles, the gastrocnemius and the soleus. These muscles are collectively known as the calf muscles. The gastrocnemius is the larger and more superficial of the two muscles, and it gives the calf its characteristic shape. The soleus is a smaller, flat muscle that lies underneath the gastrocnemius.

The gastrocnemius and soleus muscles are connected to the Achilles tendon, which attaches to the heel bone. Contraction of these muscles pulls the heel up, allowing the foot to push off the ground during walking or running.

Function[edit | edit source]

The primary function of the sura is to facilitate movement of the foot and ankle. The gastrocnemius and soleus muscles work together to flex the foot at the ankle, a movement known as plantar flexion. This is the movement that propels the body forward during walking or running.

In addition to plantar flexion, the sura also plays a role in stabilizing the leg and maintaining balance. When standing, the muscles of the sura contract to keep the body upright and prevent it from falling forward.

Clinical significance[edit | edit source]

Injuries to the sura, such as calf strain or Achilles tendonitis, can cause pain and limit mobility. Treatment for these conditions typically involves rest, physical therapy, and in some cases, surgery.
