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. Several other, smaller muscles attach ...
biceps femoris muscle, which consists of a short head and a long head. semitendinosus muscle; semimembranosus muscle; These muscles (or their tendons) apart from the short head of the biceps femoris, are commonly known as the hamstrings. The depression at the back of the knee, or kneepit is the popliteal fossa, colloquially called the ham. The ...
the scapular region encompassing the scapulae and the area around, the dorsal region encompassing the upper back; the lumbar region encompassing the lower back. the sacral region occurring at the end of the spine, directly above the buttocks. The regions of the back of the arms, from superior to inferior, include the cervical region ...
The triceps surae consists of two muscles located at the calf – the two-headed gastrocnemius and the soleus.These muscles both insert into the calcaneus, the bone of the heel of the human foot, and form the major part of the muscle of the posterior leg, commonly known as the calf muscle.
The plantaris muscle and a portion of its tendon run between the two muscles, which is involved in "locking" the knee from the standing position. Since the anterior compartment of the leg is lateral to the tibia, the bulge of muscle medial to the tibia on the anterior side is actually the posterior compartment. The soleus is superficial to the ...
Shallow pain (meaning closer to your skin) at the back of your hip could be a sign of an injury to one of the outermost muscles like the gluteus maximus. Inner hip pain. Pain on your high-inner ...
The nerve then runs straight down the back of the leg, through the popliteal fossa to supply the ankle flexors on the back of the lower leg and then continues down to supply all the muscles in the sole of the foot. [50] The pudendal (S2-S4) and coccygeal nerves (S5-Co2 [check spelling]) supply the muscles of the pelvic floor and the surrounding ...
