| Question | Answer |
|---|---|
| Define Anatomy | The study of the structure of an organism and the relationship of its parts |
| Define Physiology | The study of the function of an organism |
| Name the levels of organization within the body from smallest to largest | Atom, Molecule, Organelle, Cell, Tissue, Organ, System, Organism |
| Name 4 major tissue types | Epithelial, Connective, Muscle, Nervous |
| Name 11 major organ systems | Integumentary, Skeletal, Muscular, Nervous, Endocrine, Cardiovascular, Lymphatic, Respiratory, Digestive, Urinary, Repro |
| What does the term Anatomical Position refer to | The body when it is erect, standing upright, with arms at the sides and palms facing forward |
| Why are Directional Terms used | To describe the location of a body part with respect to another |
| Superior | Toward the head, upper, or above |
| Inferior | Toward the feet, lower, or below |
| Anterior | Front, In front of |
| Posterior | Back, In back of |
| Medial | Towards the middle of the body |
| Lateral | Towards the sides of the |
| Proximal | Towards or near the trunk of the body |
| Distal | Away from or farthest from the trunk or point of origin of a body part |
| Superficial | Near the surface of the body or shallow |
| Deep | Farther away from the surface of the body |
| Why are Organ Terms used | To describe the location of an organ in a system or region or anatomical relationship within an organ |
| Lumen/Luminal | The hollow area of an organ (stomach, airway of lungs, small intestine, blood vessels, urinary organs etc.) |
| Central | Near the center (central nervous system include brain and spinal cord) |
| Peripheral | Around the boundary (peripheral nervous system include nerves of muscles, skin, and other organs) |
| Medullary | Inner region or core of an organ |
| Cortical | Outer region or layer of an organ |
| Basal | Base or widest part of an organ |
| Apical | Narrow tip of an organ |
| Name 3 major Body Planes | Sagittal, Coronal, Transverse |
| How does a Sagittal Plane divide the body | Lengthwise separating the body or any of its parts into left and right sides |
| How does a Coronal Plane divide the body | Lengthwise separating the body or any of its parts into anterior and posterior portions |
| How does a Transverse Plane divide the body | Crosswise separating the body or any of its parts into upper and lower parts |
| What is a Dorsal Cavity and what does it include | Forms along the back of the body, includes cranial and spinal cavities, houses the brain and spinal cord |
| What is a Ventral Cavity and what sub-cavities does it include | Internal body cavity forms along the front of the body, subdivided into thoracic and abdominopelvic cavities |
| How many Abdominal Quadrants are there? Name them | 4, Right Upper Quadrant, Left Upper Quadrant, Right Lower Quadrant, Left Lower Quadrant |

| How is the body subdivided as a whole | Into Axial and Appendicular portions |
| The term Axial is used to describe | Head, Neck, and Torso |
| The term Appendicular is used to describe | Upper and Lower Extremities and their connection to the axial portion of the body |
