| Cardiovascular | The heart and blood vessels. |
| Neurophysiology | Focus on the nervous system. |
| Cell Physiology | Process within the cells. |
| Histology | Study of tissue; The collection of cells. |
| Body positions | Supine: Lying face upwardProne: Lying face downward |
| Developement | Changes in an organism over time.Differentiation: Cells change from general to specific. One type of cell can lead to many different types of blood cells.Morphogenesis: Change in shape of tissue, organs, or organism. |
| Growth | Increase in size and or number of cells. |
| Anatomical Position | Body erect, face forward, feet together, palms face forward. |
| Microscopic | Structures seen with the microscope. |
| Cytology | Cellular anatomy; Parts making up a single cell. |
| Systemic | Studied system by system (circulatory). |
| Regional Anatomy | Studies area by ares (head, abdomen, arms). |
| Surface | External form and relation to deeper structures. (See or feel/palpated the sternum-heart is beneath it). |
| Response | Produced by the effector changing the variable back to set point. |
| Stimulus | Deviation from the set point, detected by the receptor. |
| Reproduction | Formation of new cells or new organisms. |
| Responsiveness | Ability to sense changes/stimuli and adjust if needed. |
| Metabolism | Life invloves chemical reactions. |
| Organization | State in which the parts are not randomly situated but organizred to maximize function, parts must interact. |
| Sagittal | Seperates Left and Right parts of the body. |
| Coronal | Divides body into posterior & anterior sections "PAC". |
| Transverse | Divides body into superior and inferior sections "SIT". |
| Oblique | "Odd" at angle other than 90 or 0 degree. |
| Longitudinal | Cut along the length of an organ. |
| Cross/Transverse | Cut at right angle to length of the organ. |
| Diaphram | A muscle that divides the body cavity into THERACTIC and ABDOMINOPELVIC cavities. |
| Mediastinum | Contains all structures of the thorack cavity except the lungs, it divides the lungs. |
| Serous Membranes | Cover the organs inside cavities but also lines the cavity themselves. |
| Pericardium | Refers to Heart. |
| Pleura | Refers to lungs. |
| Peritoneum | Refers to abdominopelvic cavity. |
| Matter | Anything that occupies space and has mass. |
| Mass | The amount of matter in an object. |
| Weight | The gravitational force acting on an object of a given mass. |
| Element | The simplest type of matter with unique chemical properties; composed of atoms of only one kind. (H or O) |
| Atom | Smallest particles of an element that has chemical characteristics of that element. |
| Neutrons | No electrical charge. |
| Protons | One positive charge. |
| Electrons | One negative charge,orbit nucleus. |
| Nucleus | Formed by protons and neutrons. |
| Atomic Number | Equals to number of protons (+) in each atom, which is equal to the number of electrons. |
| Mass Number | Number of protons (+) plus number of neutrons. |
| Isotopes | Two or more forms of same element with same number of protons and electrons but different number of neutrons.Ex: there are 3 types of hydrogen, denoted by using symbol of element preceded by mass number as 1H,2H,3H. |
| Atomic Mass | Average mass of naturally occurring isotopes. |
| Radioactive Isotopes | Forms of atoms that emit radioactivity such as gamma rays, which can than be measured. -Used clinically and in research. |
| Intramolecular bonding | Occurs when outermose electrons are either shared with or transferred to another atom. |
| Ionic Bonding | Atoms exchange electrons, one lost it and other gained it. |
| Covalent Bonding | Two or more atoms share electron pairs. |
| Ion | An atom loses or gains electrons and becomes charged. (+/-) |
| Cation | Positively charged ion. |
| Anion | Negatively charged ion. |
| What is the symbol for Phosphate? | PO |

| Significance of Phosphate? | Part of bones and teeth, energy exchange, acid-base balance. |
| Significance of Magnesium? | Necessary for enzymes. |
| Significance of Iodide? | Present in thyroid hormones. |
| Significance of calcium? | Part of bones and teeth, blood clotting, muscle contraction, release os neurotransmitters. |
| Molecules | 2 or more atoms chemically combined to form an independent unit.Ex: (H2) |
| Compound | A substance/molecule composed of 2 or more different types of atoms chemically combined.Ex: (H2O) |
| Intermolecular forces | Forces between molecules. |
| Ionic Bond | A complete transfer of electrons between two atoms results in seperate positively charged and negatively charged ions. |
| Polar Covalent Bond | An unequal sharing of electrons between two atoms results in a slight positive charge on one side of the molecule and slight negative charge on the other side of the molecule. |
| Hydrogen Bond | The attraction of oppositely charged ends of one polar molecule to another polar molecule holds molecules or parts of molecules together. |
| Solubility | Ability of one substance to dissolve in another.Ex: Sugar or salt dissolves in water. |
| Electrolyte | Solutions made by the dissociation of cations (+) and anions (-) in water. |
| Nonelectrolytes | Solutions made by molecules that dissolve in water, but do not dissociate; do not conduct eletricity. |
