Figure one. Femur and Patella. The femur is The only bone in the thigh location. It articulates superiorly with the hip bone for the hip joint, and inferiorly Using the tibia in the knee joint. The patella only articulates with the distal close from the femur.
The talus bone articulates superiorly Using the tibia and fibula in the ankle joint, with physique weight handed from the tibia into the talus. Overall body excess weight through the talus is transmitted to the ground by both of those ends in the medial and lateral longitudinal foot arches. Body weight is handed posteriorly as a result of the two arches to your calcaneus bone, which forms the heel with the foot and is in connection with the ground. About the medial aspect in the foot, physique body weight is passed anteriorly in the talus bone to your navicular bone, then towards the medial, intermediate, and lateral cuneiform bones.

For simple causes the lower limb is subdivided into rather arbitrary regions:[44] The areas with the hip are all situated in the thigh: anteriorly, the subinguinal location is bounded via the inguinal ligament, the sartorius, plus the pectineus and varieties Section of the femoral triangle which extends distally into the adductor longus. Posteriorly, the gluteal location corresponds into the gluteus maximus. The anterior location on the thigh extends distally through the femoral triangle for the region of your knee and laterally into the tensor fasciae latae.
Extra inferiorly, the gluteal tuberosity gets continuous Along with the linea aspera (“rough line”). This can be the roughened ridge that passes distally together the posterior side with the mid-femur. Numerous muscles from the hip and thigh regions make long, slender attachments into the femur together the linea aspera.
The tibial tuberosity is undoubtedly an elevated location around the anterior aspect of your tibia, around its proximal close. It is the ultimate web page of attachment for your muscle mass tendon associated with the patella. Much more inferiorly, the shaft on the tibia here becomes triangular in shape. The anterior apex of

Inside the deep layer, the tibialis posterior has its origin within the interosseus membrane as well as neighbouring bone areas and operates down behind the medial malleolus. Under the foot it splits into a thick medial component connected towards the navicular bone and a slightly weaker lateral part inserted to the three cuneiform bones. The muscle generates simultaneous plantar flexion and supination while in the non-excess weight-bearing leg, and approximates the heel towards the calf from the leg. The flexor hallucis longus arises distally about the fibula and to the interosseus membrane from wherever its rather thick muscle mass belly extends considerably distally. Its tendon extends beneath the flexor retinaculum to the only real on the foot and finally attaches on the base of the last phalanx from the hallux.
See this link to understand a bunion, a localized swelling about the medial side of the foot, beside the primary metatarsophalangeal joint, at the base of the massive toe. Precisely what is a bunion and what sort of shoe is probably to induce this to acquire?
The ankle joint is actually a synovial hinge joint. The articular surfaces in the ankle joint are the upper area of your talus bone of the foot as website well as inferior floor in the tibia. The weight-bearing surfaces are definitely the curved trochlear on the talus as well as the reciprocal shallow notch of the tibia.
The two muscles unite to kind the iliopsoas muscle mass, which is inserted within the lesser trochanter on the femur. The psoas insignificant, only present in about 50 for each cent of topics, originates higher than the psoas major to extend obliquely down to its insertion on the interior aspect of the most important muscle mass.[sixteen]

The human adaption to bipedalism has also impacted The placement of the body's Middle of gravity, the reorganization of interior organs, and the form and biomechanism in the trunk.[nine] In humans, the double S-shaped vertebral column functions as a great shock-absorber which shifts the load within the trunk more than the load-bearing floor of your feet.
