Understanding the Skeletal System

The video tutorial provides an overview of the skeletal system, highlighting the 206 bones in the human body and their functions, such as support, protection, and movement. It categorizes bones into five types based on shape: long, short, flat, irregular, and sesamoid. Each type is explained with characteristics and examples, such as the thigh bone for long bones and the patella for sesamoid bones. The tutorial concludes with a summary of these bone types.
