Humerus
The bone of the upper arm is called the humerus. It articulates with the scapula at the shoulder joint, and the radius and ulna at the elbow.
Tibia and fibula
The tibia and fibula are the bones of the lower leg. The fibula forms the lateral part of the ankle joint, preventing dislocation in that direction.
Femur
The femur is the bone of the upper leg. The proximal end of the femur connects to the hip joint. It is marked by a spherical ball, called the femoral head, t...
