Anatomical structures refer to the various parts of the body that have specific forms and functions. These structures can be categorized into different systems, such as the skeletal system, which includes bones and joints, and the muscular system, which consists of muscles that enable movement. Each structure plays a vital role in maintaining the body's overall health and functionality. Understanding anatomical structures is essential for fields like medicine and biology. It helps professionals diagnose and treat conditions by knowing how different parts of the body interact. For example, the nervous system includes the brain and spinal cord, which are crucial for processing information and coordinating actions.
