The tibialis anterior muscle is a muscle of the anterior compartment of the lower leg. It originates from the upper portion of the tibia; it 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.
The anterior compartment of the leg is a fascial compartment of the lower leg.It contains muscles that produce dorsiflexion and participate in inversion and eversion of the foot, as well as vascular and nervous elements, including the anterior tibial artery and veins and the deep fibular nerve.
The tibia (/ ˈ t ɪ b i ə /; pl.: tibiae / ˈ t ɪ b i i / or tibias), also known as the shinbone or shankbone, is the larger, stronger, and anterior (frontal) of the two bones in the leg below the knee in vertebrates (the other being the fibula, behind and to the outside of the tibia); it connects the knee with the ankle. The tibia is found ...
The septa are formed from the fascia which is made up of a strong type of connective tissue. The fascia also separates the skeletal muscles from the subcutaneous tissue. [2] Due to the great pressure placed on the leg, from the column of blood from the heart to the feet, the fascia is very thick in order to support the leg muscles. [3]
The major bones of the leg are the femur (thigh bone), tibia (shin bone), and adjacent fibula. There are 60 bones in each leg. The thigh is located in between the hip and knee. The calf (rear) and shin (front), or shank, are located between the knee and ankle. [1]
The tibialis posterior muscle originates on the inner posterior border of the fibula laterally. [2] It is also attached to the interosseous membrane medially, which attaches to the tibia and fibula. [2] The tendon of the tibialis posterior muscle (sometimes called the posterior tibial tendon) descends posterior to the medial malleolus. [2]
The three tendons, from front to back, that conjoin to form the pes anserinus come from the sartorius muscle, the gracilis muscle, and the semitendinosus muscle. [1] [2] It inserts onto the proximal anteromedial surface of the tibia. [2] The pes anserinus is around 5 cm below the medial tibial joint line. [2]
The ankle, the talocrural region [1] or the jumping bone (informal) is the area where the foot and the leg meet. [2] The ankle includes three joints: the ankle joint proper or talocrural joint, the subtalar joint, and the inferior tibiofibular joint. [3] [4] [5] The movements produced at this joint are dorsiflexion and plantarflexion of the ...
