The patella may be the kneecap and articulates Along with the distal femur. The tibia is the much larger, excess weight-bearing bone Found about the medial facet of the leg, along with the fibula is the thin bone with the lateral leg. The bones of your foot are divided into three teams. The posterior part of the foot is formed by a group of 7 bones, Every single of which is referred to as a tarsal bone, Whilst the mid-foot consists of 5 elongated bones, Each and every of which is a metatarsal bone. The toes consist of 14 little bones, Every of which is a phalanx bone of the foot.
The epicondyles provide attachment for muscles and supporting ligaments with the knee. The adductor tubercle is a small bump Positioned within the exceptional margin on the medial epicondyle. Posteriorly, the medial and lateral condyles are divided by a deep despair known as the intercondylar fossa. Anteriorly, the smooth surfaces on the condyles sign up for alongside one another to form a broad groove known as the patellar floor, which gives for articulation Using the patella bone. The mix on the medial and lateral condyles with the patellar surface provides the distal conclusion with the femur a horseshoe (U) form.
The distal stop from the fibula sorts the lateral malleolus, which kinds the easily palpated bony bump to the lateral side with the ankle. The deep (medial) side on the lateral malleolus articulates With all the talus bone of your foot as Section of the ankle joint. The distal fibula also articulates with the fibular notch on the tibia.
articulation in between The top of the fibula and also the inferior element of the lateral condyle with the tibia
The large enlargement observed to the medial aspect from the distal tibia will be the medial malleolus (“little hammer”). This varieties the big bony bump discovered over the medial aspect in the ankle region. Both equally The sleek area on the inside on the medial malleolus and The graceful location within the distal finish with the tibia articulate with the talus bone in the foot as Element of the ankle joint.
[six] The thigh is involving the hip and knee and can make up the rest of the lower limb.[one] The phrase lower limb or lower extremity is commonly used to explain every one of the leg.
The semitendinosus functions on two joints; extension of your hip, flexion of the knee, and medial rotation in the leg. Distally, the semimembranosus' tendon is divided into 3 sections generally known as the pes anserinus profondus. Functionally, the semimembranosus is analogous towards the semitendinosus, and thus creates here extension with the hip joint and flexion and medial rotation at the knee.[24] Posteriorly down below the knee joint, the popliteus stretches obliquely through the lateral femoral epicondyle down to the posterior area from the tibia. The subpopliteal bursa is located deep into the muscle. Popliteus flexes the knee joint and medially rotates the leg.[25]
slight indentation on the head of your femur that serves as the internet site of attachment for that ligament to The top from the femur
If stretching of the ligaments is extended, excessive, or repeated, it may result in a gradual lengthening in the supporting ligaments, with subsequent despair or collapse in the longitudinal arches, specially around the medial aspect of your foot. This problem known as pes planus (“flat foot” or “fallen arches”).
The talus bone from the foot gets the burden of your body through the tibia. The talus bone then distributes this bodyweight toward the bottom in two Instructions: just one-50 percent of the body weight is handed in a very posterior route and a single-half of the burden is read more handed in an anterior course.
Both of those men and women usually look at long legs eye-catching,[sixty nine] which can explain the preference for tall trend models. Men also tend to favor women who definitely have an increased leg duration to human body ratio, but the other is genuine of ladies's preferences in Adult males.[67]
most medial from the three cuneiform tarsal bones; articulates posteriorly While using the navicular bone, laterally with the intermediate cuneiform bone, and anteriorly with the 1st and next metatarsal bones
The proximal tibia is made up of the expanded medial and lateral condyles, which articulate with the medial and lateral condyles on the femur to variety the knee joint. In between the tibial condyles would be the intercondylar eminence. Over the anterior facet of the proximal tibia is the tibial tuberosity, which can be constant inferiorly Along with the anterior border with the tibia.
deep melancholy on the posterior aspect from the distal femur that separates the medial and lateral condyles
