Determine one. Femur and Patella. The femur is The one bone on the thigh area. It articulates superiorly Along with the hip bone within the hip joint, and inferiorly Together with the tibia in the knee joint. The patella only articulates Using the distal end of the femur.
The fibula is the slender bone located on the lateral facet from the leg (see Determine (PageIndex 3 )). The fibula doesn't bear fat. It serves largely for muscle mass attachments and thus is basically surrounded by muscles. Only the proximal and distal finishes of your fibula can be palpated.
The distal finish from the femur has medial and lateral bony expansions. Around the lateral side, The graceful part that addresses the distal and posterior facets of the lateral growth may be the lateral condyle from the femur. The roughened region on the outer, lateral facet with the condyle could be the lateral epicondyle on the femur. Equally, The sleek area from the distal and posterior medial femur is the medial condyle of your femur, as well as the irregular outer, medial side of This is actually the medial epicondyle from the femur. The lateral and medial condyles articulate While using the tibia to kind the knee joint.
The lower limbs are classified as the supporting pillars once we stand. A pillar will need to have power and need to not collapse beneath the load previously mentioned. The bones, joints and muscles collectively change the lower limb into a stable assistance which can be linked to the trunk from the pelvic girdle. The pillar is divided into segments, the thigh, leg and foot.
joint Situated at the proximal conclude on the lower limb; shaped from the articulation in between the acetabulum of the hip bone and The pinnacle from the femur
Legs are useful for standing, many kinds of human motion, recreation for example dancing, and represent a good portion of a person's mass. Evolution has led for the human leg's progress right into a mechanism particularly adapted for productive bipedal gait.
irregular elevation around the exceptional close with the tibia, among the articulating surfaces from the medial and lateral condyles
The narrowed location under the head is definitely the neck of your femur. This is the lower limb supports widespread location for fractures of the femur. The bigger trochanter is the big, upward, bony projection located higher than the base of the neck. Many muscles that act throughout the hip joint connect on the higher trochanter, which, because of its projection through the femur, gives supplemental leverage to these muscles. The bigger trochanter might be felt just under the pores and skin around the lateral facet of one's higher thigh.
The acetabulum lies in the side of your pelvis and is particularly a deep, outwards-experiencing cup surrounded by a rim of fibrocartilage, often known as a labrum. The top from the femur forms the ball, which happens to be two-thirds of the sphere. here Once the ball is within the socket, the labrum curves inwards beyond the equator of the head of your femur to grip it and enable to hold it in place.
It is necessary to include the serial amount of the chair at checkout to make certain right in good shape. The support program is lightweight and simple to set up, which makes it an incredible option for These with lower extremity amputations.
The proximal end with the tibia is significantly expanded. The 2 sides of this enlargement type the medial condyle with the tibia as well as the lateral condyle of your tibia. The tibia does not have epicondyles. The best surface area of each and every condyle is smooth and flattened.
The joints from the thigh and the leg combine to present security for help from the upright body and suitable choice of movement for your limb in general.
lateral, expanded area from the proximal tibia that includes The graceful floor that articulates Along with the lateral condyle on the femur as Element of the knee joint
deep despair around the posterior aspect with the distal femur that separates the medial and lateral condyles
