The patella may be the kneecap and articulates With all the distal femur. The tibia would be the greater, weight-bearing bone Positioned around the medial facet on the leg, and also the fibula is The skinny bone from the lateral leg. The bones of your foot are divided into 3 teams. The posterior part 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 incorporates five elongated bones, Each individual of that's a metatarsal bone. The toes consist of 14 modest bones, each of and that is a phalanx bone from the foot.
small, distinguished ridge working in between the bigger and lesser trochanters to the posterior aspect of the proximal femur
The lower limb is split into three areas. These are generally the thigh, located involving the hip and knee joints; the leg, Situated amongst the knee and ankle joints; and distal to your ankle, the foot.
Femur and Patella The femur is the single bone in the thigh location. It articulates superiorly with the hip bone with the hip joint, and inferiorly While using the tibia in the knee joint. The patella only articulates Together with the distal close from the femur.
Through extension with the knee, the quadriceps femoris muscle mass pulls the patella each superiorly and laterally, While using the lateral pull increased in Ladies because of their huge Q-angle. This tends to make women more liable to acquiring patellofemoral syndrome than Adult men. Usually, the large lip about the lateral side on the patellar surface of your femur compensates to the lateral pull within the patella, and thus allows to keep up its correct monitoring.
The patella is often a sesamoid bone Found within a muscle tendon. It articulates With all the patellar floor to the anterior facet of your distal femur, thus safeguarding the muscle tendon from rubbing against the femur.
The fovea capitis is really a insignificant indentation within the medial facet in the femoral head that serves as the site of attachment for that ligament of the head on the femur. This ligament spans the femur and acetabulum, but is weak and offers tiny assist with the hip joint. It does, nevertheless, carry a vital artery that materials The pinnacle of the femur.
The lesser trochanter is a little, bony prominence that lies within the medial aspect of the femur, slightly below the neck. An individual, potent muscle mass attaches on the lesser trochanter. Operating between the larger and lesser trochanters within the anterior side with the femur may be the roughened more info intertrochanteric line. The trochanters are also related around the posterior aspect of the femur via the greater intertrochanteric crest.
The posterior half of the foot is fashioned by 7 tarsal bones ([url]). The most superior bone is definitely the talus. This has a relatively square-shaped, higher floor that articulates Together with the tibia and fibula to kind the ankle joint. Three areas of articulation form the ankle joint: The superomedial surface area of your talus bone articulates Using the medial malleolus in the tibia, the very best in the talus articulates Together with the distal conclude on the tibia, plus the lateral aspect on the talus articulates Together with the lateral malleolus on the fibula.

Pelvic tilting also occurs in response to The stress while in the hamstring muscles, which originate to the ischial tuberosities and go down the posterior element of the thigh to your knee.
The genitofemoral nerve (L1, L2) leaves psoas main underneath the two former nerves, right away divides into two branches that descends together the muscle mass's anterior side. The sensory femoral branch provides the pores and skin under the inguinal ligament, while the mixed genital branch provides the skin and muscles round the sex organ.
The angle of inclination formed concerning the neck and shaft in the femur (collodiaphysial angle) varies with age—about one hundred fifty° in the new child, it gradually decreases to 126–128° in Grownups, to succeed in 120° in outdated age. Pathological changes On this angle bring about abnormal posture in the leg: a little angle produces coxa vara and a big angle coxa valga; the latter is frequently combined with genu varum, and coxa vara qualified prospects genu valgum.
