Head of fibula, posterior tibia to calcaneus.
Posterior surface of the head and proximal quarter of the shaft of the fibula, spanning over to the soleal line and the middle third of the medial border of the tibia, and a fibrous band, which arches over the popliteal vessels and tibial nerve, between the tibia and fibula.
Joins with the tendon of the gastrocnemius to form the tendo calcaneus to attach to the middle of three facets on the posterior surface of the calcaneus. The muscle is covered proximally by gastrocnemius and is accessible on both sides.
Plantar flexes of foot.
Palmarflexion refers to movement of the flexion (palmarflexion) of the hand at the wrist.
Innervation – Nerve control
Tibial nerve, specifically, nerve roots L5–S2.
Popliteal artery, posterior tibial artery, peroneal artery.
In human anatomy, the tibialis anterior (/ˌtɪbiˈeɪlᵻs/ or /ˌtɪbiˈælᵻs/) is a muscle that originates in the upper two-thirds of the lateral (outside) surface of the tibia and inserts into the medial cuneiform and first metatarsal bones of the foot. It acts to dorsiflex and invert the foot. This muscle is mostly located near the shin. Wiki
