Femur

The bone of the thigh. The is the largest bone of the body.

The bone in the top part of the leg which joins the acetabulum at the hip and the tibia at the knee. Also called thighbone.

Thighbone, the longest and strongest bone in the body, extending from the hip to the knee. Largely cylindrical, the femur has large rounded head that fits into the acetabulum of the hipbone; a neck and shaft with projections and ridges for the attachment of muscles; and an expanded distal end that articulates with the tibia of the lower leg. Also called thigh bone.

A long bone between the hip and the knee. The head of the femur articulates with the acetabulum of the hip bone. The greater and lesser trochanters are protuberances on which the gluteus and psoas major muscles, respectively, are inserted. The lateral and medial condyles articulate with the tibia and the concave grooved patellar surface accommodates the kneecap (patella).

The thigh bone, which is the longest and strongest bone in the body. As the upper end is set at an angle of about 120 degrees to the rest of the bone, and the weight of the body is entirely borne by the two femora, fracture of one of these bones close to its upper end is a common accident in old people, whose bones are often weakened by osteoporosis. The femur fits, at its upper end, into the acetabulum of the pelvis, forming the hip-joint, and, at its lower end, meets the tibia and patella in the knee-joint.

The thigh bone. It extends from the hip to the knee and is the longest and strongest bone in the skeleton.

Heavy, long bone that forms the leg above the knee.

The femur, also known as the thigh bone, holds the distinction of being the longest bone in the human body. Its lower end interfaces with the tibia, or the shin bone, to create the knee joint. The femur’s upper end is shaped into a ball, known as the femoral head, which fits precisely into a socket in the pelvis, forming the hip joint.

The femoral head, or the top of the femur, is connected to the bone’s shaft by a slender piece of bone known as the neck of the femur. This area is often prone to fractures. At the lower end of the femur, the bone expands to form two protrusions known as the condyles, which help disperse the weight-bearing load through the knee joint. A prominent outgrowth named the greater trochanter is located on the outer side of the upper femur.

The femur’s shaft is enveloped by muscles responsible for moving the hip and knee joints. Moreover, the shaft is rich in blood supply, implying that a fracture could lead to significant blood loss.
