modest ridge running down the lateral aspect from the tibial shaft; for attachment with the interosseous membrane in between the tibia and fibula
A. The talus bone articulates superiorly While using the tibia and fibula for the ankle joint, with overall body excess weight passed through the tibia towards the talus. System bodyweight within the talus is transmitted to the ground by both equally finishes from the medial and lateral longitudinal foot arches. Body weight is handed posteriorly through both arches for the calcaneus bone, which varieties the heel from the foot and is in contact with the bottom. On the medial aspect from the foot, overall body bodyweight is handed anteriorly from your talus bone to your navicular bone, and after that to your medial, intermediate, and lateral cuneiform bones.
Anterior muscles Three in the anterior muscles are extensors. From its origin about the lateral surface in the tibia along with the interosseus membrane, the 3-sided belly on the tibialis anterior extends down under the remarkable and inferior extensor retinacula to its insertion about the plantar side on the medial cuneiform bone and the 1st metatarsal bone. While in the non-bodyweight-bearing leg, the anterior tibialis dorsal flexes the foot and lifts the medial fringe of the foot. In the load-bearing leg, it pulls the leg to the foot. The extensor digitorum longus has a broad origin stretching from your lateral condyle from the tibia down together the anterior side on the fibula, as well as interosseus membrane. On the ankle, the tendon divides into four that stretch throughout the foot to your dorsal aponeuroses of the final phalanges of the four lateral toes. During the non-body weight-bearing leg, the muscle mass extends the digits and dorsiflexes the foot, and in the load-bearing leg acts comparable to the tibialis anterior.
easy groove Found within the anterior aspect on the distal femur, concerning the medial and lateral condyles; website of articulation for your patella
View this video clip to look at how a fracture with the mid-femur is surgically repaired. How are The 2 parts of the damaged femur stabilized in the course of surgical mend of the fractured femur?
Check out this website link to study a bunion, a localized swelling on the medial side of your foot, next to the main metatarsophalangeal joint, at The bottom of the big toe. What's a bunion and what type of shoe is most probably to induce this to develop?
medial, expanded location of your proximal tibia that features The sleek surface area that articulates Using the medial condyle of the femur as part of the knee joint
(plural = phalanges) one of several fourteen bones that sort the toes; these include things like the proximal and distal phalanges of the massive toe, as well as proximal, Center, and distal phalanx bones of toes two through five
The lower limb is divided into 3 regions. These are generally the thigh, located involving the hip and knee joints; the leg, located among the knee and ankle joints; and distal to your ankle, the foot.
The gluteus maximus is mainly an extensor and lateral rotator on the hip joint, and it will come into action when climbing stairs or growing from the sitting into a standing posture. Also, the component inserted to the fascia latae abducts plus the part inserted in to the gluteal tuberosity adducts the hip. The two deep glutei muscles, the gluteus medius and minimus, originate around the lateral side from the pelvis. The medius muscle is formed similar to a cap. Its anterior fibers work as a medial rotator and flexor; the posterior fibers being a lateral rotator and extensor; and all the muscle mass abducts the hip. The minimus has related features and each muscles are inserted onto the greater trochanter.[seventeen]
The patella could be the kneecap and articulates Along with the distal femur. The tibia would be the greater, excess weight-bearing bone located to the medial aspect from the leg, and the fibula is The skinny bone on the lateral leg. The bones from the foot are divided into a few teams. The posterior portion of the foot is fashioned by a bunch of seven bones, Each individual of which is referred to as a tarsal bone, While the mid-foot contains 5 elongated bones, Each and every of which is a website metatarsal bone. The toes consist of 14 small bones, Just about every of which can be a phalanx bone of the foot.
Jumping – is an additional chance for the reason that if the legs don't land effectively soon after an First soar, there might be harm to the meniscus from the knees, sprain into the ankle by everting or inverting the foot, or harm to the Achilles tendon and gastrocnemius when there is far too much force whilst plantar flexing.[58]
lateral, expanded area of the proximal tibia that includes The graceful surface that articulates While using the lateral condyle with the femur as A part of the knee joint
The patella (kneecap) is major sesamoid bone of the body (see Determine one). A sesamoid bone is actually a bone that is integrated into your tendon of a muscle where by that tendon crosses a joint. The sesamoid bone articulates Together with the fundamental bones to stop harm to the muscle tendon as a consequence of rubbing against the bones throughout movements in the joint. The patella is present in the tendon of the quadriceps femoris muscle mass, the large click here muscle from the anterior thigh that passes throughout the anterior knee to attach to your tibia.
