The other two borders of the femur are only slightly marked: the lateral border extends from the antero-inferior angle of the greater trochanter to the anterior extremity of the lateral condyle; the medial border from the intertrochanteric line, at a point opposite the lesser trochanter, to the anterior extremity of the medial condyle.
The femur is the only bone in the upper leg. The two femurs converge medially toward the knees, where they articulate with the proximal ends of the tibiae. The angle at which the femora converge is an important factor in determining the femoral-tibial angle. In females, thicker pelvic bones cause the femora to converge more than in males.
The fovea capitis is located "slightly posterior and inferior to the center of the articular surface of the femoral head (Cerezal)" Unlike the head of the femur, the fovea capitis lacks any hyaline cartilage. The fovea capitis may contain vascular canals in two-thirds of individuals, but "their contribution to femoral head vascularity varies.
The major bones of the leg are the femur (thigh bone), tibia (shin bone), and adjacent fibula, and these are all long bones. The patella (kneecap) is the sesamoid bone in front of the knee. Most of the leg skeleton has bony prominences and margins that can be palpated and some serve as anatomical landmarks that define the extent of the leg.
It is composed of 270 bones at the time of birth, [2] but later decreases to 206: 80 bones in the axial skeleton and 126 bones in the appendicular skeleton. 172 of 206 bones are part of a pair and the remaining 34 are unpaired. [3] Many small accessory bones, such as sesamoid bones, are not included in this.
The angle is widest in infancy, and becomes lessened during growth, so that at puberty it forms a gentle curve from the axis of the body of the bone. In the adult, the neck forms an angle of about 125° with the body, but this varies in inverse proportion to the development of the pelvis and the stature. The angle decreases during the period of ...
In anatomy, the thigh is the area between the hip and the knee.Anatomically, it is part of the lower limb. [1]The single bone in the thigh is called the femur.This bone is very thick and strong (due to the high proportion of bone tissue), and forms a ball and socket joint at the hip, and a modified hinge joint at the knee.
Leg bones are the bones found in the leg. These can include the following: Femur – The bone in the thigh. Patella – The knee cap; Tibia – The shin bone, the larger of the two leg bones located below the knee cap; Fibula – The smaller of the two leg bones located below the patella
