Human Skeleton

The video tutorial explains the human skeletal system, which consists of 206 bones that provide protection, structure, support, and enable movement. It is divided into the axial skeleton, which includes the skull, vertebral column, and rib cage, primarily for protection, and the appendicular skeleton, which includes the pectoral and pelvic girdles and limbs, primarily for movement. The video highlights the flexibility of hands and feet, which contain over half of the body's bones.

How does the rib cage contribute to the body's functions?

Explain why the hands and feet are considered the most flexible parts of the body.
