The skeletal system is made up of bones, ligaments, and tendons. It provides structure and support to the body, protects internal organs, and allows for movement. The skeletal system is divided into the axial skeleton which includes the skull and vertebral column, and the appendicular skeleton which includes the upper and lower limbs. Bones have several functions including mineral storage, protection, movement, and blood cell production. There are different types of bones including long bones like the femur, flat bones like the ribs, and short or irregular bones. Joints can be fibrous, cartilaginous, or synovial, and allow different degrees of movement between bones.
