Welcome to the Visible Body Blog! The femur is the longest bone in the body. Did you know? Long bones are only one of the five types of bones found in the human body! We've also got short, sesamoid, flat, and irregular bones. The femur is a weight-bearing bone. The greater trochanter provides leverage for gluteal muscles and other muscles that rotate the thigh. The medial femoral condyle bears more weight due to the center of gravity being medial to the knee.
Being a long bone, the femur contains both red and yellow marrow. Be sure to subscribe to the Visible Body Blog for more anatomy awesomeness! Are you an instructor?

The biceps brachii, sometimes known simply as the biceps, is a skeletal muscle that is involved in the movement of the elbow and shoulder. The femur, or thigh bone, is the longest, heaviest, and strongest bone in the entire human body. Extreme forces also act upon the femur thanks to the strength of the muscles of the hip and thigh that act on the femur to move the leg.
The femur is classified structurally as a long bone and is a major component of the appendicular skeleton. On its proximal end, the femur forms a smooth, spherical process known as the head of the femur. The head of the femur forms the ball-and-socket hip joint with the cup-shaped acetabulum of the coxal hip bone. The rounded shape of the head allows the femur to move in almost any direction at the hip, including circumduction as well as rotation around its axis.
Just distal from the head, the femur narrows considerably to form the neck of the femur.
