Determine 1. Femur and Patella. The femur is The one bone in the thigh area. It articulates superiorly with the hip bone on the hip joint, and inferiorly Using the tibia for the knee joint. The patella only articulates Along with the distal end in the femur.
The talus bone articulates superiorly Along with the tibia and fibula on the ankle joint, with entire body weight handed within the tibia into the talus. Entire body excess weight with the talus is transmitted to the bottom by each ends on the medial and lateral longitudinal foot arches. Bodyweight is passed posteriorly by the two arches to the calcaneus bone, which varieties the heel in the foot and is in contact with the bottom. To the medial side from the foot, physique fat is passed anteriorly within the talus bone to your navicular bone, and afterwards towards the medial, intermediate, and lateral cuneiform bones.
The posterior 50 percent of your foot is fashioned by 7 tarsal bones (Determine (PageIndex 4 )). By far the most top-quality bone is definitely the talus. This has a comparatively sq.-formed, higher surface that articulates Along with the tibia and fibula to kind the ankle joint. A few regions of articulation sort the ankle joint: The superomedial floor with the talus bone articulates Together with the medial malleolus of the tibia, the best from the talus articulates While using the distal end of the tibia, as well as lateral facet with the talus articulates Using the lateral malleolus of your fibula.
People today not often stand to focus like guardsmen on parade, but adopt switching positions of ‘slack standing’ Along with the knees marginally flexed and the weight shifting from just one leg to another.
Far more inferiorly, the gluteal tuberosity gets to be steady With all the linea aspera (“rough line”). This can be the roughened ridge that passes distally alongside the posterior facet of your mid-femur. Many muscles on the hip and thigh regions make lengthy, thin attachments into the femur alongside the linea aspera.
The leg is made up of the large tibia about the medial side along with the slender fibula around the lateral side. The tibia bears the burden of your body, whereas the fibula would not bear fat.
Bones in the leg The foremost bones in the leg would be the femur (thigh bone), tibia (shin bone), and adjacent fibula, and these are typically all long bones. The patella (kneecap) would be the sesamoid bone before the knee. A lot of the leg skeleton has bony prominences and margins that could be palpated and some serve as anatomical landmarks that outline the extent of your leg.
Determine the areas of the lower limb, identify the bones present in Every location, and describe the bony landmarks that articulate together to sort the hip, knee, and ankle joints.
The distal conclude in the femur has medial and lateral bony expansions. On the lateral aspect, the smooth portion that handles the distal and posterior aspects of the lateral growth is the lateral condyle in the femur. The roughened space around the outer, lateral aspect with the condyle will be the lateral epicondyle on the femur. In the same way, The graceful region from the distal and posterior medial femur will be the medial condyle in the femur, along with the irregular outer, medial aspect of This is actually the medial epicondyle in the femur. The lateral and medial condyles articulate Using the tibia to type the knee joint.
The cuboid bone articulates While using the anterior stop of your calcaneus bone. The cuboid includes a deep groove running throughout its inferior surface, which presents passage for any muscle mass tendon. The talus bone articulates anteriorly Together with the navicular bone, which in turn articulates anteriorly Together with the three cuneiform (“wedge-shaped”) bones.
A bunion could also be brought on by prolonged force on the foot from pointed shoes which has a slim toe box that compresses the massive toe and pushes it toward the next toe.
The muscles linked to swing have the lower limb forwards, backwards, sideways or upwards when the alternative limb is in guidance.
Versatility could be just outlined since the offered variety of motion (ROM) supplied by a particular joint or group of joints.[37] For the most part, exercises that increase flexibility are executed with intentions to spice up Total muscle length, reduce the risks of personal injury also to perhaps increase muscular functionality in Bodily activity.
The pelvis or pelvic girdle is surely an irregular ring of bone composed of the two innominate bones and also the sacrum formed website by 5 fused vertebrae. Each innominate bone is made up of the ilium, ischium and pubis, which fuse within the socket with the hip joint. The ilium extends upwards and finishes for the iliac crest, which may be felt when putting ‘fingers on hips’.
