The patella will be the kneecap and articulates With all the distal femur. The tibia is definitely the bigger, excess weight-bearing bone located about the medial aspect of the leg, as well as fibula is the thin bone of the lateral leg. The bones of the foot are divided into a few groups. The posterior portion of the foot is formed by a gaggle of 7 bones, each of which is referred to as a tarsal bone, Whilst the mid-foot has five elongated bones, Each and every of which happens to be a metatarsal bone. The toes incorporate 14 tiny bones, Every of that is a phalanx bone in the foot.
The distal end with the femur has medial and lateral bony expansions. Within the lateral facet, The sleek portion that covers the distal and posterior aspects of the lateral enlargement is definitely the lateral condyle with the femur. The roughened place about the outer, lateral aspect from the condyle is the lateral epicondyle of your femur. In the same way, The sleek region of the distal and posterior medial femur is definitely the medial condyle on the femur, as well as the irregular outer, medial side of Here is the medial epicondyle with the femur. The lateral and medial condyles articulate Along with the tibia to kind the knee joint.
The segments are linked by joints, the hip, knee, ankle and joints of the foot, which often can change into the variations that happen in the line of excess weight with the limbs as the head and trunk transfer previously mentioned. The muscles across the joints counteract the consequences of gravity and any exterior forces that disturb the balance of the body.
The medial ligament is mostly torn, As well as in intense circumstances the anterior cruciate ligament is associated because the tibia rotates laterally. Fewer typically, the lateral ligament is torn, as well as posterior cruciate ligament tears when the tibia is pressured backwards in relation into the femur.
MH this triangle forms the anterior border of the tibia, which commences within the tibial tuberosity and operates inferiorly alongside the size from the tibia. Each the anterior border and also the medial facet of your triangular shaft can be found quickly beneath the skin and will be quickly palpated alongside the whole length of your tibia. A little ridge working down the lateral side of your tibial shaft could be the interosseous border on the tibia.
While in the standing posture, the veins of the leg have to manage an exceptional load because they act against gravity whenever they return the blood to the guts. The venous valves help in retaining the superficial to deep direction from the blood movement.[45]
Twisting accidents of the knee might arise in Activity, particularly football. The next hurt may perhaps occur:
The elongated shaft from the femur contains a slight anterior bowing or curvature. At its proximal conclude, the posterior shaft has the gluteal tuberosity, a roughened region extending inferiorly with the higher trochanter.
The patella articulates Using the patellar floor in the femur and thus prevents rubbing of your muscle mass tendon in opposition to the distal femur. The patella also lifts the tendon far from the knee joint, which increases the leverage power of your quadriceps femoris muscle as it acts throughout the knee. The patella doesn't articulate While using the tibia.
The proximal team of tarsal bones involves the calcaneus and talus bones, the navicular bone is intermediate, and the distal group includes the cuboid bone additionally the medial, intermediate, and lateral cuneiform bones.
The hip joint, similar to the glenohumeral joint with the shoulder, is actually a synovial joint from the ball and socket style, but there the similarities end. The shoulder read more joint is designed for mobility, though the hip joint should fulfil two features, click here These of mobility and balance. The socket from the hip joint is fashioned because of the acetabulum, that means ‘little vinegar cup’.
These aspects could lead to within an imbalance within the muscle pull that acts around the patella, causing an abnormal tracking with the patella that allows it to deviate much too significantly toward the lateral aspect of your patellar surface on the distal femur.
Virtually all the thigh muscles, the "real" thigh muscles, insert about the leg (both the tibia or the fibula) and act primarily on the knee joint. Frequently, the extensors lie on anterior of your thigh and flexors lie to the posterior. While the sartorius flexes the knee, it truly is ontogenetically regarded an extensor given that its displacement is secondary.[15]
Lower leg injuries are prevalent when functioning or playing sports. About 10% of all accidents in athletes include the lower extremities.[57] Many athletes sprain their ankles; this is principally due to the amplified hundreds on to the ft after they shift to the foot down or in an outer ankle place.
