What type of bone is primarily located in the arms and legs, such as the humerus and femur?

Long bones are primarily located in the arms and legs, with examples including the humerus in the upper arm and the femur in the thigh. These bones are characterized by a long cylindrical shaft and are typically longer than they are wide. They play a crucial role in facilitating movement and supporting weight, as well as serving as a site for muscle attachment and housing marrow where blood cells are produced.

The structure of long bones is designed for strength and leverage, making them essential for locomotion and other physical activities. In contrast, short bones are found in the wrists and ankles, flat bones are typically found in the skull and ribs, and irregular bones have varied shapes and are often found in the spine or pelvis. Thus, the designation of humerus and femur as long bones reflects their anatomical features and functional purposes within the human skeletal system.
