Determine one. Femur and Patella. The femur is The one bone of your thigh region. It articulates superiorly While using the hip bone for the hip joint, and inferiorly Along with the tibia for the knee joint. The patella only articulates While using the distal end of the femur.
The epicondyles present attachment for muscles and supporting ligaments of the knee. The adductor tubercle is a little bump located within the remarkable margin with the medial epicondyle. Posteriorly, the medial and lateral condyles are separated by a deep despair called the intercondylar fossa. Anteriorly, The graceful surfaces with the condyles join alongside one another to variety a wide groove known as the patellar surface area, which gives for articulation While using the patella bone. The combination of your medial and lateral condyles Along with the patellar surface offers the distal stop of the femur a horseshoe (U) form.
The tibial tuberosity is an elevated region to the anterior facet on the tibia, near its proximal end. It's the ultimate web-site of attachment with the muscle mass tendon related to the patella. Additional inferiorly, the shaft in the tibia results in being triangular in shape. The anterior apex of this triangle varieties the anterior border of the tibia, which commences for the tibial tuberosity and operates inferiorly alongside the size on the tibia. The two the anterior border as well as medial facet in the triangular shaft can be found immediately beneath the pores and skin and can be very easily palpated along your complete length of the tibia.
These variables may perhaps bring about within an imbalance inside the muscle pull that functions about the patella, resulting in an irregular monitoring from the patella that allows it to deviate far too significantly towards the lateral side in the patellar area around the distal femur.
Extra inferiorly, the gluteal tuberosity turns into ongoing While using the linea aspera (“rough line”). This is actually the roughened ridge that passes distally alongside the posterior facet of the mid-femur. Several muscles on the hip and thigh locations make long, skinny attachments on the femur alongside the linea aspera.
The proximal conclude of the tibia is considerably expanded. The two sides of the expansion sort the medial condyle of the tibia along with the lateral condyle of the tibia. The tibia does not have epicondyles. The best surface of every condyle is sleek and flattened.
irregular elevation over the remarkable finish with the tibia, among the articulating surfaces of the medial and lateral condyles
Eversion and inversion: Stretching the eversion and inversion muscles permits improved number of movement into the ankle joint.[38] Seated ankle elevations and depressions will extend the fibularis (peroneus) and tibilalis muscles which have been affiliated with these actions because they lengthen. Eversion muscles are stretched once the ankle will become frustrated through the starting up placement.
The more info patella articulates With all the patellar surface area from the femur and thus prevents rubbing of the muscle mass tendon from the distal femur. The patella also lifts the tendon from the knee joint, which improves the leverage energy with the quadriceps femoris muscle as it functions through the knee. The patella won't articulate Together with the tibia.
Bones with the Foot The bones in the foot are divided into a few groups. The posterior foot is fashioned with the seven tarsal bones. The mid-foot has the 5 metatarsal bones. The toes include the phalanges.
These instantly break up into The interior and exterior iliac arteries, the latter of which descends alongside the medial border of the psoas big to exits the pelvis location through the vascular lacuna beneath the inguinal ligament.[43]
roughened location within the posterior aspect of your proximal femur, extending inferiorly within the foundation of your bigger trochanter
The genitofemoral nerve (L1, L2) leaves psoas significant below the two former nerves, straight more info away divides into two branches that descends together the muscle mass's anterior facet. The sensory femoral department provides the skin beneath the inguinal ligament, whilst the mixed genital department materials the pores and skin and muscles throughout the sex organ.
Lower leg accidents are popular whilst managing or enjoying sports activities. About 10% of all accidents in athletes contain the lower extremities.[57] Virtually all athletes sprain their ankles; this is especially caused by the amplified hundreds on to the feet after they go into your foot down or in an outer ankle place.
