The patella could be the kneecap and articulates While using the distal femur. The tibia would be the larger sized, weight-bearing bone located around the medial aspect in the leg, along with the fibula is The skinny bone with the lateral leg. The bones with the foot are divided into a few teams. The posterior part of the foot is shaped by a bunch of seven bones, Every single of which is referred to as a tarsal bone, While the mid-foot includes five elongated bones, Each and every of which can be a metatarsal bone. The toes have 14 little bones, Every of that is a phalanx bone of the foot.
The sensory and motor innervation on the lower limb is equipped via the lumbosacral plexus, and that is fashioned from the ventral rami in the lumbar and sacral spinal nerves with supplemental contributions from your subcostal nerve (T12) and coccygeal nerve (Co1).
The distal stop in the fibula kinds the lateral malleolus, which varieties the effortlessly palpated bony bump on the lateral facet in the ankle. The deep (medial) side with the lateral malleolus articulates Together with the talus bone from the foot as Element of the ankle joint. The distal fibula also articulates Together with the fibular notch of the tibia.
Check out this video clip to view how a fracture on the mid-femur is surgically repaired. How are The 2 portions of the broken femur stabilized through surgical repair of the fractured femur?
The posterior tibial forms a immediate continuation from the popliteal artery which enters the flexor compartment with the lower leg to descend powering the medial malleolus where by it divides to the medial and lateral plantar arteries, of which the posterior department provides increase towards the fibular artery.[forty three]
The quadriceps may be the knee extensor, nevertheless the rectus femoris additionally flexes the hip joint, and articular muscle on the knee protects the articular capsule in the knee joint from currently being nipped all through extension. The sartorius runs superficially and obliquely down around the anterior aspect on the thigh, with the anterior top-quality iliac backbone to the pes anserinus around the medial side in the knee, from in which it truly is even further prolonged in the crural fascia. The sartorius functions for a flexor on both of those the hip and knee, but, due to its oblique course, also contributes to medial rotation from the leg as among the pes anserinus muscles (With all the knee flexed), and to lateral rotation from the hip joint.[23]
irregular elevation on the top-quality end from the tibia, among the articulating surfaces in the medial and lateral condyles
The narrowed location under The pinnacle would be the neck of the femur. It is a prevalent area for fractures in the femur. The larger trochanter is the massive, upward, bony projection located previously mentioned The bottom of your neck. Numerous muscles that act throughout the hip joint connect to here your greater trochanter, which, due to its projection through the femur, offers supplemental leverage to these muscles. The higher trochanter could be felt just below the pores and skin to the lateral facet within your higher thigh.
tarsal bone that articulates superiorly Along with the tibia and fibula in the ankle joint; also articulates inferiorly With all the calcaneus bone and anteriorly Together with the navicular bone
The ankle joint is actually a synovial hinge joint. The articular surfaces of your ankle joint will be the higher surface area with the talus bone from the foot and also the inferior floor of the tibia. The load-bearing surfaces are the curved trochlear in the talus and the reciprocal shallow notch with the tibia.
Response: The proximal group of tarsal bones consists of the calcaneus and talus bones, the navicular bone is intermediate, and the distal team is made up of the cuboid bone additionally the medial, intermediate, and lateral cuneiform bones.
Jumping – is yet another danger because If your legs will not land appropriately following an Original leap, there might be damage to the meniscus from the knees, sprain to your ankle by everting or inverting the foot, or damage to the Achilles tendon and gastrocnemius when there is too much pressure even though plantar flexing.[fifty eight]
The four lumbricales have their origin over the tendons with the flexor digitorum longus, from wherever they lengthen on the medial aspect in the bases of the very first phalanx of digits two-5. Except for reinforcing the plantar arch, they add to plantar flexion and transfer the four digits towards the big toe. They are, in distinction for the lumbricales of the hand, somewhat variable, occasionally absent and in some cases in excess of four are existing. The quadratus plantae occurs with two slips from margins with the plantar surface area of the calcaneus which is inserted in to the tendon(s) of your flexor digitorum longus, and is referred to as the "plantar head" of this latter muscle mass. The three plantar interossei occur with their single heads to the medial side with the third-fifth metatarsals and so are inserted around the bases of the 1st phalanges of these digits.
The pelvis or pelvic girdle is an irregular ring of bone composed of the lower limb supports two innominate bones and also the sacrum formed by five fused vertebrae. Every innominate bone is produced up from the ilium, ischium and pubis, which fuse on the socket for your hip joint. The ilium extends upwards and ends in the iliac crest, which can be felt when placing ‘hands on hips’.
