The calf (pl.: calves; Latin: sura) is the back portion of the lower leg in human anatomy. [1] The muscles within the calf correspond to the posterior compartment of the leg . The two largest muscles within this compartment are known together as the calf muscle and attach to the heel via the Achilles tendon .
Dead legs and charley horses are two different types of injuries: A charley horse involves the muscles contracting without warning, and can last from a few seconds to a couple days. A dead leg often occurs in contact sports , such as football, when an athlete suffers a knee or other blunt trauma to the lateral quadriceps causing a haematoma or ...
Acting via the Achilles tendon, the gastrocnemius and soleus muscles cause plantar flexion of the foot at the ankle. This action brings the sole of the foot closer to the back of the leg. The gastrocnemius also flexes the leg at the knee. Both muscles are innervated by the tibial nerve. [14]
For improved ankle mobility, ankle circles—rotating your ankle clockwise and counterclockwise while seated or standing—are beneficial. Similarly, heel walks, where you walk on your heels with toes lifted, strengthen the tibialis anterior and enhance balance. Using equipment like resistance bands can add versatility to your routine.
The lateral malleolus is the prominence on the outer side of the ankle, formed by the lower end of the fibula. The word malleolus ( / m ə ˈ l iː ə l ə s , m æ -/ [ 1 ] [ 2 ] ), plural malleoli ( / m ə ˈ l iː ə ˌ l aɪ , m æ -/ ), comes from Latin and means "small hammer ".
Simone Biles fought through an apparent ankle injury on Sunday to post an impressive all-around score and display the qualities which have made one of the greatest gymnasts of all time on her ...
The calf muscles are your “second heart,” squeezing veins in the lower legs to help return deoxygenated blood from the feet back up towards the chest, the Cleveland Clinic notes.
The fibula does not carry any significant load (weight) of the body. It extends past the lower end of the tibia and forms the outer part of the ankle providing stability to this joint. It has grooves(a depression) for certain ligaments which gives them leverage and multiplies the muscle force. It provides attachment points for the following ...
