The internal skeleton of a vertebrate, known as the endoskeleton, is primarily composed of bone and cartilage. This structure provides support, protects vital organs, and facilitates movement by serving as an attachment point for muscles. The vertebrate skeleton is divided into two main parts: the axial skeleton, which includes the skull, vertebral column, and rib cage, and the appendicular skeleton, which consists of the limbs and their associated girdles. This internal framework is crucial for the overall structure and function of vertebrate organisms.
