rounded, proximal stop of the femur that articulates While using the acetabulum with the hip bone to kind the hip joint
The fovea capitis is a insignificant indentation around the medial side on the femoral head that serves as the internet site of attachment for your ligament of The top with the femur. This ligament spans the femur and acetabulum, but is weak and provides small assist with the hip joint. It does, nevertheless, carry a significant artery that materials The pinnacle of the femur.
The distal close with the femur has medial and lateral bony expansions. On the lateral side, The sleek part that addresses the distal and posterior areas of the lateral enlargement will be the lateral condyle in the femur. The roughened region about the outer, lateral facet of your condyle is the lateral epicondyle from the femur. In the same way, the smooth location with the distal and posterior medial femur is definitely the medial condyle on the femur, plus the irregular outer, medial facet of Here is the medial epicondyle of the femur. The lateral and medial condyles articulate Together with the tibia to type the knee joint.
The tibial tuberosity is surely an elevated space about the anterior facet from the tibia, close to its proximal conclusion. It is the remaining web site of attachment with the muscle mass tendon related to the patella. Far more inferiorly, the shaft in the tibia becomes triangular in condition. The anterior apex of
Observe this movie to watch how a fracture with the mid-femur is surgically fixed. How are The 2 portions from the damaged femur stabilized in the course of surgical restore of the fractured femur?
The lower limb is split into three locations. The thigh could be the region Situated amongst the hip and knee joints. It contains the femur as well as the patella. The hip joint is fashioned by the articulation in between the acetabulum from the hip bone and The pinnacle of the femur. The leg could be the region among the knee and ankle joints, and includes the tibia (medially) along with the fibula (laterally). The knee joint is formed from the articulations among the medial and lateral condyles on the femur, along with the medial and lateral condyles with the tibia. Also affiliated with the knee is the patella, which articulates Using the patellar floor in the distal femur.
sleek, articulating surface area that sorts the distal and more info posterior sides in the medial enlargement of the distal femur
Outline the areas with the lower limb, identify the bones found in each location, and explain the bony landmarks that articulate collectively to kind the hip, knee, and ankle joints.
During extension in the knee, the quadriceps femoris muscle mass pulls the patella the two superiorly and laterally, Using the lateral pull larger in Females because of their huge Q-angle. This will make Females extra vulnerable to producing patellofemoral syndrome than Males. Commonly, the large lip about the lateral facet in the patellar surface area with the femur compensates for your lateral pull to the patella, and so aids to take care of its proper monitoring.
Tiny action is needed inside the hip flexors and extensors. The paraplegic with paralysed hip muscles learns to put the hips nicely before the road of gravity and relies solely on The strain from the iliofemoral ligament for security in the hips in standing (Figure 8.5a).
The hip joint, like the glenohumeral joint at the shoulder, is a synovial joint of the ball and socket form, but there the similarities conclusion. The shoulder joint is created for mobility, though the hip joint has to fulfil two functions, Individuals of mobility and security. The socket of your hip joint is formed because of the acetabulum, meaning ‘small vinegar cup’.
The posterior fifty percent from the foot is shaped by 7 tarsal bones (Figure 4). One of the most top-quality bone is the talus. This has a relatively square-shaped, higher surface that articulates with the tibia and fibula to type the ankle joint. Three areas of articulation form the ankle joint: The superomedial area of the talus bone articulates with the medial malleolus of the tibia, the top of the talus articulates with the distal end of the tibia, and the lateral facet on the talus articulates Together with the lateral malleolus in the fibula.
most lateral with the 3 cuneiform tarsal bones; articulates posteriorly Along with the navicular bone, medially Along with the intermediate cuneiform bone, laterally While using the cuboid bone, and anteriorly While using the 3rd metatarsal bone
During the pelvis area, at the level of the last lumbar vertebra, the abdominal aorta, a continuation the descending aorta, splits into a pair of typical iliac arteries.
