Figure one. Femur and Patella. The femur is The one bone on the thigh region. It articulates superiorly Along with the hip bone with the hip joint, and inferiorly Using the tibia for the knee joint. The patella only articulates Using the distal conclude of the femur.
The talus bone articulates superiorly Along with the tibia and fibula with the ankle joint, with physique excess weight handed within the tibia to your talus. Human body bodyweight through the talus is transmitted to the bottom by both finishes with the medial and lateral longitudinal foot arches. Fat is passed posteriorly as a result of equally arches towards the calcaneus bone, which sorts the heel with the foot and it is in connection with the bottom. On the medial side on the foot, system weight is passed anteriorly through the talus bone to your navicular bone, and then for the medial, intermediate, and lateral cuneiform bones.
Explain the arrangement of the tarsal and metatarsal bones which are associated with both equally the posterior and anterior distribution of system weight.
The muscles in the leg and thigh is going to be explained less than a few headings associated with their perform in assist, swing and propulsion.
The posterior tibial types a immediate continuation of the popliteal artery which enters the flexor compartment in the lower leg to descend guiding the medial malleolus where it divides in to the medial and lateral plantar arteries, of which the posterior department offers increase towards the fibular artery.[43]
The talus articulates inferiorly Along with the calcaneus bone. The sustentaculum tali with the calcaneus helps you to assistance the talus. Anterior to your talus may be the navicular bone, and anterior to this are classified as the medial, intermediate, and lateral cuneiform bones. The cuboid bone is anterior on the calcaneus.
The opponens digiti minimi originates in the prolonged plantar ligament and the plantar tendinous sheath in the fibularis (peroneus) longus which is inserted on the fifth metatarsal. When present, it acts to plantar flex the fifth digit and supports the plantar arch. The flexor digiti minimi occurs within the region of base of the fifth metatarsal and is also inserted on to The bottom of the first phalanx in the fifth digit in which it is frequently merged with the abductor of the very first digit.
The narrowed region under The top is definitely the neck from the femur. It is a prevalent area for fractures from the femur. The increased trochanter is the massive, upward, bony projection Found above the base in the neck. A number of muscles that act through the hip joint connect to the higher trochanter, which, as a result of its website projection through the femur, offers more leverage to those muscles. The bigger trochanter can be felt just under the skin around the lateral side of one's upper thigh.
Check out this hyperlink to learn about a bunion, a localized swelling to the medial aspect from the foot, next to the 1st metatarsophalangeal joint, at The bottom of the large toe. What's a bunion and what sort of shoe is most probably to result in this to develop?
The arches of your foot Enjoy a crucial role With this shock-absorbing capacity. When weight is placed on the foot, these arches will flatten fairly, thus absorbing Electricity. When the burden is taken out, the arch rebounds, giving “spring” to your stage. The arches also provide to distribute entire body pounds aspect to facet and to possibly finish of your foot.
The patella may be the kneecap and articulates Using the distal femur. The tibia is definitely the more substantial, excess weight-bearing bone Found within the medial facet in the leg, and the fibula is The skinny bone of the lateral leg. The bones in the foot are divided into a few teams. The posterior portion of the foot is shaped by a gaggle of 7 bones, Each and every of which is referred to as a tarsal bone, whereas the mid-foot consists of 5 elongated bones, Each individual of that is a metatarsal bone. The toes incorporate fourteen small bones, Every of that's a phalanx bone with the foot.
This pathological fracture is particularly viewed in more mature individuals, when osteoporosis has weakened the bone. This fracture can interrupt the key blood provide to the head of the femur as well as bone may perhaps are unsuccessful to unite (avascular necrosis).
extensive groove over the lateral side from the distal tibia for articulation Together with the fibula within the distal tibiofibular joint
The longitudinal arches run down the size with the foot. The lateral longitudinal arch is pretty flat, whereas the medial longitudinal arch is more substantial (taller). The longitudinal arches are fashioned via the tarsal bones posteriorly as well as the metatarsal bones anteriorly. These arches are supported at both conclusion, where they Get in touch with the ground. Posteriorly, this assist is supplied by the calcaneus bone and anteriorly because of the heads (distal finishes) of the metatarsal bones. The talus bone, which receives the weight of the body, is located at the very best in the longitudinal arches. Overall body weight is then conveyed in the talus to the ground with the anterior and posterior finishes of such arches.
