The human ankle and foot bones include tarsals ankle , metatarsals middle bones , and phalanges toes. It also provides sensory innervation to the skin of the leg anterolateral and postero-lateral aspect.
Consequently, any pathology of the lower extremity severely affects our mobility, thus impairing most daily activities and occupations. The proximal or upper extremity of the tibia is expanded in the transverse plane with a medial and lateral condyle , which are both flattened in the horizontal plane.
Extension of the knee. While these medial and lateral arches may be readily demonstrated as the component antero-posterior arches of the foot, the fundamental longitudinal arch is contributed to by both, and consists of the calcaneus, cuboid, third cuneiform, and third metatarsal: Nerves of the lower extremity The innervation of the lower leg begins upstream at the lombo-sacral region of the spine with a bundles of nerves that together form the lumbo-sacral plexus.
Lastly, there are two ligaments on the dorsal side of the knee. The tuberosity of the tibial head allows for the insertion of the patellae ligament.

In come cases, you can avoid knee pain altogether! Retrieved 6 February These injuries often develop slowly over weeks or months. Ligaments of the knee The knee is supported by four principal ligaments, which are elastic fibrous bands connecting bones to bones.
As with the tibia, the shaft of the fibula is triangular and numerus muscles are involved in the extension and flexion of the foot. Its summit is at the talocalcaneal articulation, and its chief joint is the calcaneocuboid, which possesses a special mechanism for locking and allows only a limited movement. The MCL is partly covered by the pes anserinus and the tendon of the semimembranosus passes under it. For other uses, see Tibia disambiguation.

The Vertebrate Body. A smooth prominence on a bone where it forms a joint with another bone. The tibia or shin bone is the largest bone located to the inner leg-side. Its main role is to connect the muscles of the lower leg rather than weight bearing mainly taken up by the tibia.
The anterior surface of the lower extremity is smooth and rounded above, and covered by the tendons of the Extensor muscles; its lower margin presents a rough transverse depression for the attachment of the articular capsule of the ankle-joint.
The medial condyles superior surface is oval in form and extends laterally onto the side of medial intercondylar tubercle. In addition, weakening of tissues around the knee may contribute to the problem. Licenses and Attributions.
It is made by the calcaneus, the talus, the navicular, the three cuneiforms, and the first, second, and third metatarsals. The intercondylar eminence divides the intercondylar area into an anterior and posterior part. Posteriorly, the condyles are separated from each other by a shallow depression, the posterior intercondyloid fossa , which gives attachment to part of the posterior cruciate ligament of the knee-joint.
