Labelled skeleton diagram

Humans have skeletons and muscles as essential components of their anatomy, serving multiple crucial functions. The skeleton provides a rigid structure that supports the body, protects vital organs, and anchors muscles. It also facilitates movement by acting as a system of levers that muscles can pull on to create motion. Additionally, bones store minerals and produce blood cells. Muscles, on the other hand, are responsible for producing force and movement, maintaining posture, and generating body heat through muscle contractions.

The body parts associated with the skeleton include the skull, which encases the brain; the jaw bone, crucial for chewing; the backbone, or spine, that supports the body and protects the spinal cord; the collarbone, or clavicle, which stabilizes the shoulder; the shoulder blade, or scapula, that allows for shoulder movement; and the humerus, which is the upper arm bone. The rib cage protects the chest organs and the radius and ulna are the bones of the forearm. Cartilage provides cushioning at joints. The pelvis supports the lower body, the thighbone, or femur, is the upper leg bone, the kneecap, or patella, covers the knee joint, the shinbone, or tibia, supports the lower leg, and the anklebones facilitate foot movement. These skeletal components work in tandem with muscles to enable a wide range of activities and functions that are vital for survival and interaction with the environment.
