The Achilles tendon or heel cord, also known as the calcaneal tendon, is a tendon at the back of the lower leg, and is the thickest in the human body. [1][2][3][4][5][6][excessive citations] It serves to attach the plantaris, gastrocnemius (calf) and soleus muscles to the calcaneus (heel) bone. These muscles, acting via the tendon, cause ...
It forms a joint with the talus bone, the subtalar joint. In humans and many other primates, the calcaneus (/ kælˈkeɪniəs /; from the Latin calcaneus or calcaneum, meaning heel; [1] pl.: calcanei or calcanea) or heel bone is a bone of the tarsus of the foot which constitutes the heel. In some other animals, it is the point of the hock.
Five central part plantar aponeurosis bundles. The plantar fascia is the thick central portion of the fascia investing the plantar muscles. It extends between the medial process of the tuber calcanei [1] and the proximal phalanges of [citation needed] the toes. It provides some attachment to the flexor muscles of the toes.
The talus (/ ˈteɪləs /; Latin for ankle [1] or ankle bone; [2] pl.: tali), talus bone, astragalus (/ əˈstræɡələs /), or ankle bone is one of the group of foot bones known as the tarsus. The tarsus forms the lower part of the ankle joint. It transmits the entire weight of the body from the lower legs to the foot. [3]
Gastrocnemius muscle. Right leg seen from behind. The gastrocnemius muscle (plural gastrocnemii) is a superficial two-headed muscle that is in the back part of the lower leg of humans. It is located superficial to the soleus in the posterior (back) compartment of the leg. It runs from its two heads just above the knee to the heel, extending ...
Soleus muscles have more slow muscle fibers than many other muscles. In some animals, such as the guinea pig and cat, soleus consists of 100% slow muscle fibers. [6] [7] Human soleus fiber composition is variable, containing between 60% and 100% slow fibers. [8] The soleus is the most effective muscle for plantarflexion in a bent knee position.

Contents. Subtalar joint. Ligaments of the medial aspect of the foot. In human anatomy, the subtalar joint, also known as the talocalcaneal joint, is a joint of the foot. It occurs at the meeting point of the talus and the calcaneus. The joint is classed structurally as a synovial joint, [ 1 ] and functionally as a plane joint.
