Posterior aspect of head and superior quarter of posterior surface of fibula; soleal line and middle third of medial border of tibia; and tendinous arch extending between the bony attachments: Plantarflexes ankle independent of position of knee; steadies leg on foot
Calf (leg) 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.
The fascial compartments of the leg are the four fascial compartments that separate and contain the muscles of the lower leg (from the knee to the ankle). The compartments are divided by septa formed from the fascia. The compartments usually have nerve and blood supplies separate from their neighbours. All of the muscles within a compartment ...
Tibialis posterior muscle. The mucous sheaths of the tendons around the ankle. Medial aspect. (Tibialis posterior labeled at top center.) The tibialis posterior muscle is the most central of all the leg muscles, and is located in the deep posterior compartment of the leg. It is the key stabilizing muscle of the lower leg.
Cross-section through the middle of the thigh. (Posterior compartment is at center bottom.) Back of left lower extremity. The posterior compartment of the thigh is one of the fascial compartments that contains the knee flexors and hip extensors known as the hamstring muscles, as well as vascular and nervous elements, particularly the sciatic nerve.
The piriformis muscle (from Latin piriformis ' pear-shaped ') is a flat, pyramidally-shaped muscle in the gluteal region of the lower limbs. It is one of the six muscles in the lateral rotator group. The piriformis muscle has its origin upon the front surface of the sacrum, and inserts onto the greater trochanter of the femur.
In human anatomy, the lower leg is the part of the lower limb that lies between the kneeand the ankle.[1] Anatomists restrict the term legto this use, rather than to the entire lower limb.[6] The thighis between the hipand kneeand makes up the rest of the lower limb.[1] The term lower limbor lower extremityis commonly used to describe all of ...
The biceps femoris (/ ˈ b aɪ s ɛ p s ˈ f ɛ m ər ɪ s /) is a muscle of the thigh located to the posterior, or back. As its name implies, it consists of two heads; the long head is considered part of the hamstring muscle group, while the short head is sometimes excluded from this characterization, as it only causes knee flexion (but not hip extension) [1] and is activated by a separate ...
