Latin. arcus pedis. Anatomical terminology. [edit on Wikidata] The arches of the foot, formed by the tarsal and metatarsal bones, strengthened by ligaments and tendons, allow the foot to support the weight of the body in the erect posture with the least weight. They are categorized as longitudinal and transverse arches.
The human foot is a strong and complex mechanical structure containing 26 bones, 33 joints (20 of which are actively articulated), and more than a hundred muscles, tendons, and ligaments. [2] The joints of the foot are the ankle and subtalar joint and the interphalangeal joints of the foot. An anthropometric study of 1197 North American adult ...
The Achilles tendon or calcaneal tendon is attached to the gastrocnemius and soleus muscles. 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 ...
The tendons of both of these muscles cross as they reach their distal attachments. In other words, the flexor hallucis longus arises laterally, while the flexor digitorum longus arises medially. The amount of flexion is very considerable, but extension is limited by the plantar and collateral ligaments .
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.
Ligaments of the sole of the foot, with the tendons of the peronaeus longus, tibialis posterior and tibialis anterior muscles. The plantar ligaments consist of longitudinal and oblique bands, disposed with less regularity than the dorsal ligaments.
The deltoid ligament (or medial ligament of talocrural joint) is a strong, flat, triangular band, attached, above, to the apex and anterior and posterior borders of the medial malleolus. The deltoid ligament supports the ankle joint and also resists excessive eversion of the foot. [1] The deltoid ligament is composed of 4 fibers: Anterior ...
In human anatomy, the fibularis longus (also known as peroneus longus) is a superficial muscle in the lateral compartment of the leg. It acts to tilt the sole of the foot away from the midline of the body (eversion) and to extend the foot downward away from the body (plantar flexion) at the ankle. The fibularis longus is the longest and most ...
