The big enlargement discovered on the medial facet of your distal tibia will be the medial malleolus (“very little hammer”). This sorts the large bony bump identified to the medial aspect with the ankle region. Both equally the smooth area on the inside with the medial malleolus and The sleek space with the distal conclusion from the tibia articulate Together with the talus bone of the foot as A part of the ankle joint.

The patella articulates With all the patellar surface area of the femur and thus stops rubbing of the muscle mass tendon in opposition to the distal femur. The patella also lifts the tendon far from the knee joint, which improves the leverage electric power on the quadriceps femoris muscle since it functions across the knee. The patella will not articulate with the tibia.

The segments are joined by joints, the hip, knee, ankle and joints on the foot, which might alter to the changes that manifest in the line of pounds throughout the limbs as The pinnacle and trunk go previously mentioned. The muscles within the joints counteract the results of gravity and any external forces that disturb the balance of your body.

limited, outstanding ridge running amongst the greater and lesser trochanters about the posterior facet on the proximal femur

The leg has the large tibia around the medial side and the slender fibula on the lateral facet. The tibia bears the burden of the human body, Whilst the fibula would not bear pounds.

The patella is really a sesamoid bone Found in a muscle tendon. It articulates While using the patellar surface area on the anterior facet in the distal femur, thus safeguarding the muscle tendon from rubbing from the femur.

All through extension on the knee, the quadriceps femoris muscle pulls the patella both of those superiorly and laterally, Together with the lateral pull higher in Women of all ages due to their large Q-angle. This would make Females more prone to creating patellofemoral syndrome than Adult males. Typically, the massive lip about the lateral facet in the patellar area in the femur compensates with the lateral pull within the patella, and so aids to take care of its correct monitoring.

These regions articulate Along with the website medial and lateral condyles of the femur to form the knee joint. Among the articulating surfaces of your tibial condyles will be the intercondylar eminence, an irregular, elevated spot that serves given that the inferior attachment stage for two supporting ligaments on the knee.

Actions within the hip enable the thigh to maneuver from the frontal, sagittal and transverse planes. The knee, such as elbow, moves predominantly in a single aircraft (sagittal), and makes it possible for shortening on the lower limb so the foot can very clear the ground in walking.

Small activity is necessary inside the hip flexors and extensors. The paraplegic with paralysed hip muscles learns to place the hips perfectly before the line of gravity and depends completely on the tension from the iliofemoral ligament for balance at the hips lower limb supports in standing (Determine 8.5a).

The proximal close on the tibia is tremendously expanded. The 2 sides of this growth form the medial condyle on the tibia as well as lateral condyle from the tibia. The tibia doesn't have epicondyles. The very best surface area of each and every condyle is smooth and flattened.

It is felt being a uninteresting, aching ache within the front with the knee and deep to the patella. The discomfort can be felt when going for walks or operating, heading up or down stairs, kneeling or squatting, or soon after sitting down with the knee bent for an extended time period.

most lateral from the a few cuneiform tarsal bones; articulates posteriorly Together with the navicular bone, medially With all the intermediate cuneiform bone, laterally With all the cuboid bone, and anteriorly with the 3rd metatarsal bone

Such as the higher limb, the lower limb is split into a few regions. The thigh is part of the lower limb Found between the hip joint and knee joint. The leg is precisely the region amongst the knee joint plus the ankle joint. Distal into the ankle will be the foot. The lower limb includes thirty bones. These are definitely the femur, patella, tibia, fibula, tarsal bones, metatarsal bones, and phalanges. The femur is the single bone from the thigh.
