The term lower limb or lower extremity is commonly used to describe all of the leg. The leg from the knee to the ankle is called the crus . [ 7 ] The calf is the back portion, and the tibia or shinbone together with the smaller fibula make up the shin , the front of the lower leg.
In humans and some other mammals, the soleus is a powerful muscle in the back part of the lower leg (the calf). It runs from just below the knee to the heel and is involved in standing and walking. It is closely connected to the gastrocnemius muscle, and some anatomists consider this combination to be a single muscle, the triceps surae.
The thickness of the fascia can give problems when any inflammation present in the leg has little room to expand into. Blood vessels and nerves can also be affected by the pressure caused by any swelling in the leg. If the pressure becomes great enough, blood flow to the muscle can be blocked, leading to a condition known as compartment ...
The gastrocnemius is primarily involved in running, jumping and other "fast" movements of leg, and to a lesser degree in walking and standing. This specialization is connected to the predominance of white muscle fibers (type II fast twitch) present in the gastrocnemius, as opposed to the soleus, which has more red muscle fibers (type I slow ...
the olecranal region encompassing the back of the elbow, the antebrachial region encompasses the forearm, front and back; and the manual or manus region encompassing the back of the hand. The posterior regions of the legs, from superior to inferior, include the gluteal region encompassing the buttocks, the femoral region encompassing the thigh,
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.
Plantarflexes ankle when knee is extended; raises heel during walking; flexes leg at knee joint Plantaris: Inferior end of lateral supracondylar line of femur; oblique popliteal ligament: Weakly assists gastrocnemius in plantarflexing ankle Soleus
The word fibula can be dated back to c. 1670. It derives from Latin fībula, which describes a clasp or brooch – see fibula (brooch) – and was first used in English for the smaller bone in the lower leg c. 1706. The bone was so called because it resembles a clasp like a modern safety pin.
