The patella is definitely the kneecap and articulates While using the distal femur. The tibia could be the greater, excess weight-bearing bone located on the medial facet from the leg, as well as fibula is the thin bone with the lateral leg. The bones on the foot are divided into three groups. The posterior percentage of the foot is shaped by a group of seven bones, Each individual of which is named a tarsal bone, whereas the mid-foot includes 5 elongated bones, Each individual of that is a metatarsal bone. The toes consist of 14 small bones, Every of that's a phalanx bone from the foot.
Plantar flexion if the motion is in the alternative way from the neutral place (Figure 8.4). Plantar flexion lifts the heel off the ground to offer propulsion forwards in strolling, and upwards in standing on the toes. The ankle is minimum secure while in the plantar flexed position.
The posterior half in the foot is shaped by 7 tarsal bones (Determine (PageIndex four )). Essentially the most outstanding bone is the talus. This has a relatively square-shaped, higher floor that articulates Using the tibia and fibula to variety the ankle joint. 3 areas of articulation form the ankle joint: The superomedial surface on the talus bone articulates While using the medial malleolus with the tibia, the top in the talus articulates Using the distal stop of your tibia, plus the lateral side from the talus articulates While using the lateral malleolus from the fibula.
The tibial tuberosity is surely an elevated space about the anterior facet from the tibia, close to its proximal conclude. It's the last web page of attachment for that muscle tendon associated with the patella. A lot more inferiorly, the shaft in the tibia gets triangular in condition. The anterior apex of
More inferiorly, the gluteal tuberosity results in being continual With all the linea aspera (“rough line”). This is the roughened ridge that passes distally along the posterior side with the mid-femur. A number of muscles of the hip and thigh locations make long, skinny attachments to your femur together the linea aspera.
The patella (kneecap) is most significant sesamoid bone of the body (see Figure (PageIndex one )). A sesamoid bone is really a bone that is certainly included into your tendon of a muscle mass wherever that tendon crosses a joint. The sesamoid bone articulates with the underlying bones to prevent damage to the muscle tendon as a consequence of rubbing against the bones through actions of your joint. The patella is located in the tendon of your quadriceps femoris muscle mass, the massive muscle mass of your anterior thigh that passes throughout the anterior knee to connect towards the tibia.
The 5 metatarsal bones sort the anterior foot. The bottom of these bones articulate Using the cuboid or cuneiform bones. The metatarsal heads, at their distal ends, articulate With all the proximal phalanges with the toes.
(plural = phalanges) among the 14 bones that type the toes; these contain the proximal and distal phalanges of the large toe, plus the proximal, Center, and distal phalanx bones of toes two as a result of 5
In the course of extension of the knee, the more info quadriceps femoris muscle mass pulls the patella both superiorly and laterally, Along with the lateral pull better in Women of all ages due to their significant Q-angle. This helps make women a lot more liable to establishing patellofemoral syndrome than men. Commonly, the large lip over the lateral side on the patellar surface with the femur compensates with the lateral pull within the patella, and so aids to take care of its correct monitoring.
View this video clip to see how a fracture in the mid-femur is surgically repaired. How are the two portions of the damaged femur stabilized throughout surgical fix of a fractured femur?
A gap is drilled into your bigger trochanter, the bone marrow (medullary) space inside the femur is enlarged, and finally an intramedullary rod is inserted into the femur. This rod is then anchored to the bone with screws.
The joints of your thigh plus the leg Merge to provide stability for aid in the upright body and enough array of motion for your limb in general.
Plantar flexion: Amongst the most well-liked lower leg muscle stretches is definitely the phase standing heel raises, which primarily will involve the gastrocnemius, soleus, along with the Achilles tendon.[41] Standing heel raises make it possible for the individual to activate their calf muscles by standing with a phase with toes and forefoot, leaving the heel hanging from the phase, and plantar flexing more info the ankle joint by raising the heel.
From the anterior thigh muscles the biggest are classified as the 4 muscles on the quadriceps femoris: the central rectus femoris, and that is surrounded via the a few vasti, the vastus intermedius, medialis, and lateralis. Rectus femoris is hooked up into the more info pelvis with two tendons, though the vasti are inserted into the femur. All 4 muscles unite in a standard tendon inserted into your patella from where by the patellar ligament extends it all the way down to the tibial tuberosity. Fibers within the medial and lateral vasti variety two retinacula that extend previous the patella on both sides right down to the condyles from the tibia.
