Types of Anatomy

• Gross anatomy: The study of the structures that can be seen with the naked eye, such as organs, bones, and muscles.
• Microscopic anatomy: The study of the structures that can only be seen with the aid of a microscope, such as cells and tissues.
• Developmental anatomy: The study of how organisms grow and develop from conception to adulthood.
• Comparative anatomy: The study of the similarities and differences in the structure of different species.

Anatomical Terminology
