How many kinds of anatomy are there?

Anatomy is generally divided into two main types: gross anatomy and microscopic anatomy. Gross anatomy, or macroscopic anatomy, involves the study of structures visible to the naked eye, while microscopic anatomy focuses on structures at the cellular and tissue levels, often using microscopes. Additionally, anatomy can be categorized by system (e.g., skeletal, muscular) or by region (e.g., cranial, thoracic). Other specialized areas include developmental anatomy and comparative anatomy.
