Final answer:
Humans have an endoskeleton consisting of 206 bones in adults, along with cartilage and ligaments. The skeleton supports the body, facilitates movement, and protects organs.
Step-by-step explanation:
Humans have an endoskeleton in which bones are associated with soft tissues and are found inside the body. The human skeleton is an internal framework that, in adults, consists of 206 bones. Bones are organs made up of living tissues that include blood vessels, nerves, and other tissues. This framework is not just bone, but also includes cartilage and ligaments. Cartilage is a dense connective tissue that provides a smooth surface for the movement of bones at joints, such as the knee. Ligaments, on the other hand, are bands of fibrous tissue that connect bones and help to keep them in place. The skeleton plays a crucial role in supporting the body, facilitating movement, protecting internal organs, and more.
