The knee is a substantial, sophisticated synovial joint, which can be termed an atypical hinge joint. The key axis of movement flexes and extends the leg to the thigh, but there's some rotation with the knee when the knee is flexed along with the foot is off the bottom.

The head with the fibula will be the tiny, knob-like, proximal conclusion of the fibula. It articulates With all the inferior facet of the lateral tibial condyle, forming the proximal tibiofibular joint. The skinny shaft of your fibula has the interosseous border of the fibula, a narrow ridge operating down its medial facet for that attachment in the interosseous membrane that spans the fibula and tibia.

smaller, knob-like, proximal conclusion on the fibula; articulates Together with the inferior aspect of the lateral condyle from the tibia

smooth groove located within the anterior side of the distal femur, in between the medial and lateral condyles; web site of articulation for that patella

2a). The posture from the cruciate ligaments from the centre of the joint implies that they avert the femur rolling from the tibia. The cruciate ligaments also form a fulcrum to the ‘locking motion’ of your knee, which occurs once the femur rotates a little medially at the conclusion of full extension.

lateral, expanded region of your proximal tibia that includes The graceful surface area that articulates Along with the lateral condyle of your femur as A part of the knee joint

Once the foot comes into connection with the ground during going for walks, jogging, or jumping actions, the impression of your body bodyweight puts an incredible number of strain and pressure over the foot. During working, the force placed on Every foot because it contacts the ground could be as many as two.5 occasions One's body pounds. The bones, joints, ligaments, and muscles from the foot take up this power, As a result considerably reducing the amount of shock that is certainly handed superiorly in the lower limb and system.

Within the lateral aspect of the distal tibia is a large groove known as the fibular notch. This area articulates Together with the distal close from the fibula, forming the distal tibiofibular joint.

The hip joint has a strong capsule that features almost all of the femoral neck. The capsule is even more strengthened by extremely strong ligaments anteriorly, and by smaller fifty percent rotator cuff muscles posteriorly. ThFe iliofemoral ligament will be the strongest in the human body; it truly is Y-shaped, passing through the front of the joint (Determine 8.

small ridge working down the medial aspect on the fibular shaft; for attachment with the interosseous membrane concerning the fibula and tibia

The bottom on the fifth metatarsal has a sizable, lateral enlargement that provides for muscle mass attachments. This expanded base of your fifth metatarsal might be felt as a bony bump for the midpoint along the lateral border with the foot. The expanded distal stop of each and every metatarsal is The top of the metatarsal bone. Every single metatarsal bone articulates Using the proximal phalanx of the toe to form a metatarsophalangeal joint. The heads on the metatarsal bones also relaxation on the ground and sort the ball (anterior finish) on the foot.

This pathological fracture is especially observed in more mature men and women, when osteoporosis has weakened the bone. This fracture can interrupt the primary blood offer to the head website of your femur plus the bone could fail to unite (avascular necrosis).

most lateral of the 3 cuneiform tarsal bones; articulates posteriorly With all the navicular bone, medially with the intermediate cuneiform bone, laterally Along with the cuboid bone, and anteriorly Together with the third metatarsal bone

The abductor hallucis stretches along the medial fringe of the foot, through the calcaneus to the base of the main phalanx of the primary digit as well as the medial sesamoid bone. It is an abductor in addition to a weak flexor, and in addition assists manage the arch on the foot. Lateral towards the abductor hallucis is definitely the flexor hallucis brevis, which originates through the medial cuneiform bone and from the tendon with the tibialis posterior. The flexor hallucis includes a medial in addition to a lateral head inserted laterally for the abductor hallucis.
