Determine 1. Femur and Patella. The femur is the single bone of the thigh location. It articulates superiorly While using the hip bone within the hip joint, and inferiorly Along with the tibia with the knee joint. The patella only articulates Together with the distal stop from the femur.
The patella articulates Along with the patellar surface on the femur and so prevents rubbing on the muscle mass tendon towards the distal femur. The patella also lifts the tendon faraway from the knee joint, which improves the leverage electrical power with the quadriceps femoris muscle because it functions through the knee. The patella doesn't articulate Using the tibia.
The posterior 50 % from the foot is shaped by 7 tarsal bones (Figure (PageIndex four )). By far the most excellent bone could be the talus. This has a comparatively square-shaped, higher surface that articulates with the tibia and fibula to type the ankle joint. 3 regions of articulation kind the ankle joint: The superomedial floor with the talus bone articulates While using the medial malleolus with the tibia, the best of your talus articulates with the distal finish from the tibia, as well as the lateral aspect in the talus articulates With all the lateral malleolus in the fibula.
Quite a few procedures could be used that can help Management ache attributable to shin splints. Placing ice over the impacted location just before and soon after managing will assist in reducing discomfort. On top of that, donning orthotic equipment including a neoprene sleeve (Determine two) and putting on proper footwear for instance a foot arch can assist to get rid of the ailment.
The anterior half in the foot is fashioned through the 5 metatarsal bones, which can be found between the tarsal bones in the posterior foot plus the phalanges of the toes (see Figure (PageIndex 4 )). These elongated bones are numbered 1–5, starting off While using the medial side in the foot. The primary metatarsal bone is shorter and thicker when compared to the others. The next metatarsal could be the longest. The bottom of the metatarsal bone will be the proximal conclude of every metatarsal bone. These articulate Along with the cuboid or cuneiform bones.
The lumbar plexus is fashioned lateral on the intervertebral foramina from the ventral rami of the 1st four lumbar spinal nerves (L1-L4), which all go through psoas major. The much larger branches from the plexus exit the muscle mass to go sharply downward to reach the abdominal wall as well as thigh (under the inguinal ligament); with the exception of the obturator nerve which go through the lesser pelvis to reach the medial Component of the thigh with the obturator foramen.
The semitendinosus acts on two joints; extension from the hip, flexion on the knee, and medial rotation of your leg. Distally, the semimembranosus' tendon is divided into three elements often called the pes anserinus profondus. Functionally, the semimembranosus is analogous to your semitendinosus, and thus produces extension for the hip joint and flexion and medial rotation within the knee.[24] Posteriorly below the knee joint, the popliteus stretches obliquely with the lateral femoral epicondyle down to the posterior surface area of your tibia. The subpopliteal bursa is found deep into the muscle. Popliteus flexes the knee joint and medially rotates the leg.[twenty five]
minimal indentation on The top with the femur that serves as the location of attachment for your ligament to The top with the femur
little ridge functioning involving the larger and lesser trochanters within the anterior side in the proximal femur
The arches on the foot Engage in a vital position With this shock-absorbing capacity. When body weight is applied to the foot, these arches will flatten to some degree, Hence absorbing Strength. When the load is taken out, the arch rebounds, offering “spring” towards the move. The arches also serve to distribute overall body excess weight facet to side and also to possibly finish with the foot.
The patella is definitely the kneecap and articulates While using the distal femur. The tibia is definitely the much larger, body weight-bearing bone Positioned within the medial side of your leg, as well as fibula is The skinny bone in the lateral leg. The bones from the foot are divided into a few teams. The posterior portion of the foot is fashioned by a group of 7 bones, Each and every of which is named a tarsal bone, While the mid-foot contains five elongated bones, each of that's a metatarsal bone. The toes include fourteen little bones, Just about every of that is a phalanx bone with the foot.
tarsal bone that articulates superiorly With all the tibia and fibula within the ankle joint; also articulates inferiorly here With all the calcaneus bone and anteriorly Along with the navicular bone
These bones tend to be the medial cuneiform, the intermediate cuneiform, plus the lateral cuneiform. Just about every of those bones incorporates a broad exceptional surface and a slender inferior surface area, which collectively generate the transverse (medial-lateral) curvature from the foot. The navicular and lateral cuneiform bones also articulate with the medial facet with the cuboid bone.
The cuboid bone articulates Using the anterior end of your calcaneus bone. The cuboid contains a deep groove jogging across its inferior surface, which gives passage for the muscle tendon. The talus bone articulates anteriorly Using the navicular bone, which in turn articulates anteriorly with the a few cuneiform (“wedge-formed”) bones.
