A skeleton is the internal framework of bones that supports the body of many living organisms, including humans. It provides structure, protects vital organs, and allows for movement by serving as attachment points for muscles. In humans, the skeleton consists of 206 bones at adulthood, which can be categorized into two main parts: the axial skeleton and the appendicular skeleton. In addition to providing support, the skeleton plays a crucial role in producing blood cells and storing minerals like calcium and phosphorus. The study of skeletons, known as osteology, helps scientists understand the health and evolution of different species, including dinosaurs and other ancient creatures.
