The lesser trochanter is a small, bony prominence that lies around the medial aspect of the femur, slightly below the neck. Only one, impressive muscle mass attaches on the lesser trochanter. Managing amongst the better and lesser trochanters within the anterior side of the femur is the roughened intertrochanteric line. The trochanters are related within the posterior side of the femur because of the much larger intertrochanteric crest.

The epicondyles present attachment for muscles and supporting ligaments on the knee. The adductor tubercle is a small bump Found on the excellent margin with the medial epicondyle. Posteriorly, the medial and lateral condyles are divided by a deep depression called the intercondylar fossa. Anteriorly, The graceful surfaces of your condyles be part of jointly to kind a wide groove called the patellar area, which presents for articulation with the patella bone. The mix on the medial and lateral condyles Together with the patellar surface offers the distal finish on the femur a horseshoe (U) form.

Propulsion muscles exert forces on the ground to propel the human body horizontally or upwards in going for walks, leaping or climbing stairs.

smooth, articulating surface that types the distal and posterior sides with the lateral enlargement of your distal femur

The proximal tibia is made of the expanded medial and lateral condyles, which articulate While using the medial and lateral condyles with the femur to sort the knee joint. Amongst the tibial condyles would be the intercondylar eminence. Within the anterior side of the proximal tibia is definitely the tibial tuberosity, and that is constant inferiorly With all the anterior border from the tibia.

The patella (kneecap) is major sesamoid bone of the body (see Figure (PageIndex 1 )). A sesamoid bone is actually a bone that is definitely included into your tendon of the muscle mass where that tendon crosses a joint. The sesamoid bone articulates Using the underlying bones to avoid damage to the muscle tendon as a result of rubbing from the bones all through actions of the joint. The patella is found in the tendon from the quadriceps femoris muscle, the big muscle in the anterior thigh that passes throughout the anterior knee to attach on the tibia.

The epicondyles present attachment for muscles and supporting ligaments of your knee. The adductor tubercle is a little bump located at the remarkable margin with the medial epicondyle. Posteriorly, the medial and lateral condyles are divided by a deep despair known as the intercondylar fossa. Anteriorly, The graceful surfaces from the condyles join with each other to more info type a wide groove called the patellar surface, which presents for articulation Along with the patella bone. The mixture of the medial and lateral condyles While using the patellar floor provides the distal stop in the femur a horseshoe (U) shape.

The sacroiliac joint concerning the sacrum as well as ilium of your innominate bone is usually a joint that is an element synovial and aspect fibrous. The ear-formed irregular joint surfaces, about the posterior medial Section of the ilium as well as the upper lateral side of your sacrum, in shape closely.

The lower limb is divided into 3 areas. These are the thigh, Positioned concerning the hip and knee joints; the leg, located amongst the knee and ankle joints; and distal to the ankle, the foot.

The artery enters the thigh because the femoral artery which descends the medial aspect in the thigh on the adductor canal. The canal passes with the anterior into the posterior facet of your limb where the artery leaves through the adductor hiatus and gets to be the popliteal artery.

Because the hips are broader when compared to the knee area, the femur features a diagonal orientation throughout the thigh, in contrast into the vertically oriented tibia on the leg (Figure two). The Q-angle is really a evaluate of how much the femur is angled laterally clear of vertical. The Q-angle is Generally 10–15 levels, with women ordinarily obtaining a bigger Q-angle due to their wider pelvis.

The joints in the thigh and the leg Blend to provide stability for assist from the upright system and ample selection of motion for your limb in general.

Typically, the massive joints of the lower limb are aligned within a straight line, which signifies the mechanical longitudinal axis in the leg, the Mikulicz line. This line stretches within the hip joint read more (or more specifically the head on the femur), through the knee joint (the intercondylar eminence in the tibia), and all the way down to the center with the ankle (the ankle mortise, the fork-like grip between the medial and lateral malleoli). While in the tibial shaft, the mechanical and anatomical axes coincide, but during the femoral shaft they diverge 6°, leading to the femorotibial angle of 174° within a leg with usual axial alignment.

The base of the fifth metatarsal has a considerable, lateral expansion that gives for muscle attachments. This expanded foundation of your fifth metatarsal is usually felt as a bony bump in the midpoint along the lateral border from the foot. The expanded distal finish of each metatarsal is the head from the metatarsal bone. Each and every metatarsal bone articulates Along with the proximal phalanx of the toe to sort a metatarsophalangeal joint. The heads with the metatarsal bones also relaxation on the bottom and kind the ball (anterior conclude) in the foot.
