| Term | Definition |
|---|---|
| Anatomy | "A for architecture" Structures of the body Their physical relationship to one another |
| Physiology | "P for purpose" Study of function How processes of life work |
| Gross (macroscopic) anatomy | Examines large visible structures: -surface anatomy: exterior landmarks -regional anatomy: body areas -sectional anatomy: cross sections -systemic anatomy: organ systems) -developmental anatomy: from embryo to adulthood |
| Microscopic anatomy | Study of structures we cannot see without magnification |
| Cytology | The study of individual cells |
| Histology | The study of tissues which are specialized cells that make up organs |
| Human physiology | The study of functions of the human body |
| Cell physiology | Function of cells, the chemistry in them and how they communicate |
| Organ physiology | Functions of specific organs |
| Systemic physiology | Function of organ systems |
| Pathological physiology | Effects of diseases on organs or system functions |
| Symptoms | Subjective changes in body function that are not apparent to observer |
| Signs | Objective changes that are observed measured reported by clinician |
| Scientific method | Observation Question Hypothesis Experiment Analysis Conclusion |
| Body organization: Chemical | Atoms combine to form molecules |
| Cellular | Cells are the smallest living unit in the body |
| Tissue | A group of cells working together to perform one or more functions |
| Organ | Made of two or more tissues working together for a specific purpose |
| Organ system | Group of organs interacting to perform one or more functions |
| Organism | An individual life form |
| Organ systems -integumentary | Major organs - skin -hair -nails -sweat glands |
| Skeletal | -Bones -cartilage -associated ligaments -bone marrow |
| Muscular | -skeletal muscles and associated tendons |
| Nervous | -Brain -spinal cord -peripheral nerves -sense organs |
| Endocrine | -pituitary gland -thyroid gland -pancreas -adrenal glands -gonads -endocrine tissues in other systems |

| -Surface Anatomy | Structures on or near the body surface that can be seen and used as reference points |
| Anatomical landmarks | Structures that can be felt |
| Anatomical regions | Specific areas used for reference purposes |
| Anatomical directions | Closer or further away from a structure or plane |
| -Anatomical position | Hands at side, palms forward -posterior (dorsal) -anterior (ventral) |
| Supine | Lying down face up |
| Prone | Lying down face down |
| Lateral recumbent | Lying on one's side |
| Trendelenburg | Lying down head downwards feet upwards / |
| Abdominal quadrants | Four spaces defined by perpendicular lines that intersect at the navel (umbilicus) Right upper quadrant, left. Right lower quadrant, left. |
| Abdominopelvic regions | 9 spaces defined to show relationship between internal organs |
| Abdominopelvic regions | Right hypochondriac region, left Right lumbar region, left Right inguinal region, left Middle: epigastric, umbilical, hypogastric |
| Anatomical directions - superior | Above |
| Inferior | Below |
| Anterior | In front of |
| Posterior | Behind |
| Medial | Middle |
| Lateral | Away from middle, to the outer sides |
| Intermediate | Close to the middle, close to the outer sides |
| Proximal | Close to the body part |
| Distal | Away from the body part |
| Superficial | External, at the surface |
| Deep | Internal, away from surface |
| Cranial/Cephalic | Toward the head |
