The leg is the entire lower limb of the human body, including the foot, thigh or sometimes even the hip or buttock region. The major bones of the leg are the femur (thigh bone), tibia (shin bone), and adjacent fibula.
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]
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 ...
A common injury that is normally attributed to the plantaris muscle is a condition called tennis leg. Although pain in the calf can be attributed to a rupture of the plantaris muscle, recent ultrasound research has shown that tennis leg more commonly arises from tears in the musculotendinous junction of the medial gastrocnemius. In one clinical ...
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 ".
Plantar fasciitis or plantar heel pain is a disorder of the plantar fascia, which is the connective tissue that supports the arch of the foot. [2] It results in pain in the heel and bottom of the foot that is usually most severe with the first steps of the day or following a period of rest.
The fibula (pl.: fibulae or fibulas) or calf bone is a leg bone on the lateral side of the tibia, to which it is connected above and below. It is the smaller of the two bones and, in proportion to its length, the most slender of all the long bones.
