What type of bones are primarily associated with weight support and movement?

Long bones are primarily associated with weight support and movement due to their structural characteristics and function within the skeletal system. They are typically longer than they are wide, with a shaft (diaphysis) that contains the medullary cavity, where bone marrow is stored. Long bones, such as the femur, tibia, and humerus, play a crucial role in facilitating movement by providing levers for muscles to act upon.

Additionally, these bones are designed to bear weight and withstand the forces exerted during activities such as walking, running, and jumping. The dense and heavy nature of long bones also contributes to their strength, allowing them to support the weight of the body and provide stability during movement. This functional aspect distinguishes them from other types of bones, each of which has different roles in the body.
