Determine one. Femur and Patella. The femur is the single bone on the thigh location. It articulates superiorly Together with the hip bone within the hip joint, and inferiorly Using the tibia with the knee joint. The patella only articulates While using the distal finish in the femur.
With the popliteus (see higher than) as The only exception, all muscles inside the leg are attached on the foot and, based upon site, is often categorized into an anterior plus a posterior team separated from one another through the tibia, the fibula, as well as the interosseous membrane. In turn, these two groups is often subdivided into subgroups or levels—the anterior group consists of the extensors as well as the peroneals, along with the posterior team of a superficial plus a deep layer.
If the foot comes into connection with the ground for the duration of walking, jogging, or jumping functions, the effect of the human body bodyweight places an incredible quantity of strain and power about the foot. In the course of jogging, the power applied to each foot as it contacts the bottom is often approximately two.five situations One's body fat. The bones, joints, ligaments, and muscles of your foot take up this force, Therefore drastically minimizing the amount of shock that is definitely handed superiorly to the lower limb and human body.
Mountaineers have heightened possibility for significant leg accidents. This is mostly as a result of not enough health care help in mountainous parts, along with motion impairment limiting usage of other health-related services.
The patella articulates Along with the patellar surface on the femur and therefore helps prevent rubbing in the muscle tendon versus the distal femur. The patella also lifts the tendon clear of the knee joint, which raises the leverage electrical power of your quadriceps femoris muscle since it acts over the knee. The patella does not articulate Together with the tibia.
[6] The thigh is involving the hip and knee and tends to make up the remainder of the lower limb.[1] The phrase lower limb or lower extremity is usually utilized to explain all the leg.
There are actually 4 posterior thigh muscles. The biceps femoris has two heads: The lengthy head has its origin around the ischial tuberosity together with more info the semitendinosus and acts on two joints. The brief head originates from the center third of the linea aspera over the shaft of your femur as well as lateral intermuscular septum of thigh, and acts on just one joint. Both of these heads unite to kind the biceps which inserts on The top in the fibula. The biceps flexes the knee joint and rotates the flexed leg laterally—it is the only lateral rotator with the knee and therefore has to oppose all medial rotator. On top of that, the extended head extends read more the hip joint. The semitendinosus and the semimembranosus share their origin While using the prolonged head of the biceps, and both equally attaches around the medial facet from the proximal head of the tibia along with the gracilis and sartorius to kind the pes anserinus.
(plural = phalanges) one of the fourteen bones that type the toes; these include the proximal and distal phalanges of the large toe, and also the proximal, Center, and distal phalanx bones of toes two by way of five
The head on the fibula is the smaller, knob-like, proximal close of the fibula. It articulates Using the inferior element of the lateral tibial condyle, forming the proximal tibiofibular joint. The skinny shaft on the fibula has the interosseous border with the fibula, a slim ridge jogging down its medial facet for the attachment from the interosseous membrane that spans the fibula and tibia.
smaller ridge jogging down the medial facet with the fibular shaft; for attachment of your interosseous membrane between the fibula and tibia
The fibula may be the slender bone Positioned to the lateral facet of the leg (see [website link]). The fibula won't bear weight. It serves largely for muscle mass attachments and thus is largely surrounded by muscles. Only the proximal and distal finishes of the fibula could be palpated.
The posterior half from the foot is shaped by 7 tarsal bones (Figure four). Probably the most remarkable bone will be the talus. This has a comparatively sq.-shaped, higher surface area that articulates While using the tibia and fibula to type the ankle joint. lower limb supports A few parts of articulation type the ankle joint: The superomedial floor of the talus bone articulates with the medial malleolus on the tibia, the best from the talus articulates Along with the distal finish on the tibia, as well as lateral side of the talus articulates with the lateral malleolus from the fibula.
Around the lateral facet on the distal tibia is a wide groove known as the fibular notch. This region articulates with the distal conclusion in the fibula, forming the distal tibiofibular joint.
The joint is bound by anterior and posterior ligaments. The skinny joint cavity frequently results in being fused by fibrous bands with age. The 2 innominate bones join anteriorly for the pubic symphysis, a secondary cartilaginous joint.
