Name | Description |
---|---|
Anatomy | study of the structure of the human body |
Physiology | study of the functions of the human body |
Macroscopic (Gross) | regional, systemic, surface |
Regional Anatomy | study as it relates to regions |
Systemic Anatomy | study as it relates to body systems |
Surface Anatomy | study of internal organs as they relate to overlying skin |
Microscopic | cytology, histology |
Cytology | study of cells |
Histology | study of tissues |

Embryology | study of development before birth |
Renal Physiology | study of the kidneys |
Neurophysiology | study of the nerves |
Cardiovascular Physiology | study of the heart and blood vessels |
Complementarity of Structure & Function | what a structure can do depends on its form |
Atoms | building-block parties |
Molecules | combination of atoms to form new substances |
