| Question | Answer |
|---|---|
| Gross Anatomy | Study of body structures that can be examined by the naked eye. |
| Dissection | Removal of connective tissue from between body organs so that they can be seen more clearly |
| Physiology | The study of body function |
| Morphology | Science of form; another term for anatomy. |
| Anatomy | The study of structure of the human body. |
| Regional Anatomy | The study of all structures in a single body region, such as the abdomen or the head. |
| Systemic Anatomy | The study of organs with related functions, such as the muscular system. |
| Surface Anatomy | The study of shapes and markings (landmarks) on the surface of the body that reveal the underlying organs. |
| Microscopic Anatomy | The study of structures that are so small they can be seen only with a microscope. |
| Histology | "tissue study" |
| Developmental Anatomy | The study of structural changes that occur in the body during the lifespan. |
| Embryology | The study of how body structures develop and form before birth. |
| Pathological Anatomy | The study of structural changes in cells, tissues and organs caused by disease. |
| Radiographic Anatomy | The study of internal body structures by means of X-ray studies and other imaging techniques. |
| Functional Morphology | The study of the functional properties of body structures and efficiency of design. |
| Anatomical Position | Erect, feet together and eyes forward. Palms face forward with the thumbs pointed away from the body. |

| Frontal (Coronal) Plane | Vertical plane that divides the body into front (anterior) and back (posterior) sections. |
| Transverse (Horizontal) Plane | Horizontal plane that divides the body into superior and inferior sections. Also called a cross-section. |
| Sagittal Plane | Vertical plane that divides the body into right and left sections. |

| Pericardial Cavity | Cavity that contains the heart. |
| Abdominal Cavity | Cavity that contains the liver, stomach, kidneys and other organs. |
| Pelvic Cavity | Below the abdominal cavity, contains the urinary bladder, some reproductive organs and the rectum. |
| Peritoneal Cavity | Cavity that surrounds some organs in the abdomen, such as the liver, stomach and intestines. |
| Retroperitoneal Cavity | "Behind" the peritoneal cavity, contains the kidneys, spleen, pancreas. |
| Serous Membrane/Serosa | Membrane that either lines the walls of a cavity (Parietal) or surrounds an organ (Visceral) |
| Serous Cavity | The space between the parietal and visceral serous membranes. Contains serous fluid. |
