Femur
The "femur" is the thigh bone, the longest bone in the body. The lower
end joins the tibia (shin) to form the knee joint. The upper end is
rounded into a ball (or "head" of the femur) that fits into a socket in
the pelvis to form the hip joint. Just below the head is a constriction,
or neck, and two large processes - an upper, lateral "greater trochanter"
and a lower, medial "lesser trochanter." These processes provide
attachments for muscles of the legs and buttocks. Femoral condyles are large,
rounded bumps on the distal end of the femur. They articulate (come in contact)
with the condyles of the tibia and form part of the knee joint. The neck of
the femur gives the hip joint a wide range of movement, but it is a point
of
weakness and a common site of fracture.
