The lesser trochanter is a little, bony prominence that lies on the medial facet of the femur, slightly below the neck. An individual, potent muscle mass attaches towards the lesser trochanter. Running among the greater and lesser trochanters within the anterior aspect of your femur is the roughened intertrochanteric line. The trochanters may also be linked to the posterior facet of the femur through the more substantial intertrochanteric crest.
Inferiorly, the talus articulates with the calcaneus (heel bone), the most important bone of the foot, which forms the heel. Physique body weight is transferred with the tibia to your talus to the calcaneus, which rests on the bottom. The medial calcaneus features a distinguished bony extension known as the sustentaculum tali (“help for your talus”) that supports the medial facet of the talus bone.
The posterior half on the foot is formed by 7 tarsal bones (Figure (PageIndex four )). One of the most outstanding bone will be the talus. This has a comparatively square-formed, upper surface that articulates with the tibia and fibula to sort the ankle joint. Three regions of articulation variety the ankle joint: The superomedial surface area of your talus bone articulates With all the medial malleolus of your tibia, the very best in the talus articulates While using the distal stop with the tibia, as well as lateral aspect of your talus articulates Along with the lateral malleolus on the fibula.
Femur and Patella The femur is The only bone in the thigh location. It articulates superiorly With all the hip bone for the hip joint, and inferiorly Using the tibia with the knee joint. The patella only articulates Together with the distal conclude of your femur.
tarsal bone that articulates posteriorly with the calcaneus bone, medially While using the lateral cuneiform bone, and anteriorly Along with the fourth and fifth metatarsal bones
In human anatomy, the lower leg may be the A part of the lower limb that lies between the knee and the ankle.[one] Anatomists restrict the expression leg to this use, instead of to all the lower limb.
Stretching on the ligaments that support the longitudinal arches can cause pain. This will manifest in overweight folks, with Individuals who have jobs that entail standing for extensive periods of time (such as a waitress), or walking or working extended distances.
joint that separates the thigh and leg portions of your lower limb; formed with the articulations concerning the medial and lateral condyles from the femur, along with the medial and lateral condyles of your tibia
The femur is The only bone of the thigh. Its rounded head articulates Along with the acetabulum in the hip bone to form the hip joint. The pinnacle has the fovea capitis for attachment of the ligament of the head of your femur. The slender neck joins inferiorly Together with the better and lesser trochanters. Passing concerning these bony expansions tend to be the intertrochanteric line around the anterior femur as well as greater intertrochanteric crest over the posterior femur.
The ankle joint is usually a synovial hinge joint. The articular surfaces with more info the ankle joint tend to be the upper area in the talus bone of the foot plus the inferior surface area of your tibia. The load-bearing surfaces are the curved trochlear with the talus as well as the reciprocal shallow notch of your tibia.
Truly feel the front of the knee joint and locate the patella. A few fingers’ breadth underneath the lower border on the patella you may come to feel a big lump. This is actually the anterior tubercle of the tibia where the quadriceps is inserted.
Stop by This page to execute a Digital knee alternative operation. The prosthetic knee elements has to be correctly aligned to click here operate appropriately. How Is that this alignment ensured?
Typically, the big joints on the lower limb are aligned in a very straight line, which signifies the mechanical longitudinal axis with the leg, the Mikulicz line. This line stretches within the hip joint (or maybe more specifically The pinnacle of your femur), in the knee joint (the intercondylar eminence of your tibia), and all the way down to the middle with the ankle (the ankle mortise, the fork-like grip concerning the medial and lateral malleoli). During the tibial shaft, the mechanical and anatomical axes coincide, but during the femoral shaft they diverge six°, leading to the femorotibial angle of 174° in the leg with standard axial alignment.
In the anterior thigh muscles the biggest tend to be the 4 muscles of the quadriceps femoris: the central rectus femoris, that is surrounded through the 3 vasti, the vastus intermedius, medialis, and lateralis. Rectus femoris is connected to your pelvis with two tendons, though the vasti are inserted to the femur. All 4 muscles unite in a standard tendon inserted into the patella from exactly where the patellar ligament extends it down to the tibial tuberosity. Fibers from your medial and lateral vasti kind two retinacula that stretch past the patella on either sides down to the condyles from the tibia.
