The three divisions of anatomy
- Gross/macroscopic anatomy
- Microscopic anatomy
- Developmental anatomy/ Embryology
What is gross anatomy?
Gross anatomy is the study of structural details that are visible to the naked or unaided eye that are revealed after dissection.
What is microscopic anatomy?
Microscopic anatomy is the study of structures using visual aids.
Branches of microscopic anatomy
- Cytology
2. Histology
Difference between cytology and histology
Cytology is the study of cells and their internal structure, whereas histology is the study of tissues.
Developmental anatomy/ embryology
Embryology is the study of the stages through which an organism evolves from conception to birth.
The two approaches to gross anatomy
- Regional or topographical anatomy
2. Systematic anatomy
Regional or topographical anatomy
Organs or structures are studied region by region in the body in relation to surrounding structures (eg. thoracic region, lumbar region etc)
Regional anatomy includes…
- Surface anatomy
- Applied anatomy
- Radiological anatomy
Systematic anatomy
The study of groups of organs with closely related functions, forming organ systems.
