The human skeleton, an internal framework, serves as the structural support for the body. It consists of approximately 270 bones at birth, which decreases to around 206 bones by adulthood… The human skeleton has two main subdivisions: the axial skeleton, which includes the vertebral column and much of the skull, and the appendicular skeleton, which includes the pelvic and pectoral girdles and the bones and cartilages of the limbs. The skeletal system provides support and protection for the body's internal organs and gives the muscles a point of attachment.
