What are the main parts to skeletal system?

The skeletal system consists of bones, cartilage, and ligaments.

Bones are the hard, mineralized tissues that form the skeleton. They provide support, protection, and leverage for movement. Bones also store minerals, such as calcium and phosphorus, and produce blood cells.

Cartilage is a flexible, connective tissue that covers the ends of bones and lines the joints. It helps to reduce friction and provides cushioning.

Ligaments are tough, fibrous bands of tissue that connect bones together. They help to stabilize the joints and prevent them from dislocating.

The skeletal system is divided into two main parts: the axial skeleton and the appendicular skeleton.

The axial skeleton consists of the bones of the head, neck, and trunk. It includes the skull, the spine (vertebrae), the ribs, and the sternum.

The appendicular skeleton consists of the bones of the limbs (arms and legs). It includes the shoulders, the hips, the upper arms (humerus), the forearms (ulna and radius), the wrists (carpals), the hands (metacarpals and phalanges), the thighs (femur), the lower legs (tibia and fibula), the ankles (tarsals), and the feet (metatarsals and phalanges).

The skeletal system is a complex and important part of the human body. It provides support, protection, and movement, and it stores minerals and produces blood cells.
