Skeletal system
The skeletal system is the body's internal support structure made up of bones, cartilage, ligaments, and tendons. It provides shape to the body, supports and protects vital organs, allows movement by working with muscles, produces blood cells, stores minerals, and helps maintain overall bodily structure and function. The system consists of 206 bones in adults, divided into the axial skeleton (skull, vertebral column, ribs, sternum) and the appendicular skeleton (shoulder girdle, pelvic girdle, limbs). It plays crucial roles such as protecting organs like the brain and heart, facilitating movement, and housing bone marrow that produces blood cells.
