- Gross anatomy: the study of body structures visible to the naked eye (without a microscope)
- Microscopic anatomy:
- Cytology: Analysis of the internal structures of individual cell
- Histology: examination of tissues (groups of specialized cells that work together to perform a specific function.
Anatomical Position
- Anytime you describe structures relative to one another, you must assume this standard position:
- Body erect
- Feet slightly apart
- Palms facing forward
- Thumbs point away from body
