Terms | Definitions |
|---|---|
 Anatomy | Science of the structure of an organism and the relations of its parts. |
| Gross Anatomy | the study of the structure of the body and its parts without the use of a microscope |
| Microscope Anatomy | what can be seen with a microscope |
| Physiology | Science of the functions of organisms. |
| Autopoiesis | Living organisms are self organized and self maintaining. |
| Metabolism | sum total of all physical and chemical reactions occurring in the living body. |
| Responsiveness | Sensing, monitoring and responding to environmental changes (internal and external). |
| Absorption | Movement of molecules through a membrane and into the body. |
| Levels of Organization: Chemical Level | basis for life. -Organization of chemical structures separates living material from nonliving material. |
| Levels of Organization: Organelle Level | Chemical structures organized t form organelles that perform individual functions. |
| Levels of Organization: Cellular Level | Smallest and most numerous units that posses and exhibit characteristics of life. |
| Levels of Organization: Tissue Level | An organization of similar cells specialized to perform a certain function. |
| Levels of Organization: Organ Level | Organization of several different kinds of tissues to perform a specific function. |
| Levels of Organization: System Level | System level involves varying numbers and kinds of organs arranged to perform complex functions. |
| Levels of Organization: Organism Level | one complete living human unit. |
| Anatomical Position | Body erect with arms at sides and palms forward. |
| Bilateral Symmetry | left and right sides are mirror images in anatomical position. |
| Superficial | near body surface. |
| Deep | not near body surface. |
| Superior | toward head |
| Inferior | toward bottom |
| Sagittal | DIVIDES THE BODY INTO LEFT AND RIGHT SIDES, NOT IN THE MIDDLE |
| Transverse | horizontal. separates superior from inferior. |
| Frontal | Coronal. Separates anterior from posterior. |
| Anterior | front |
| Posterior | back |
| Proximal | closer to the trunk |
| Distal | limbs |
| Medial | toward midline |
| Lateral | toward the side. |
| Body Cavities | Spaces lined with a double membrane fluid filled sac. (no separation of membranes between abdominal and pelvic. |
| Homeostasis | Is used to describe the relatively constant states maintained by the body; the internal environment around body cells remains constant. |
| Negative Feedback Control Systems | -Are inhibitory -stabilize physiological variables -produce an action opposite to the change that activated the system. are responsible for maintaining homeostasis |
| Positive Feedback Control Systems | -Are stimulatory -amplify or reinforce the change that is occurring -bring specific body functions to swift completion. |
| Atrophy | Term to describe the wasting effects of advancing age. |
| Lyse or Lysis | to split |
| What was being lysed in the cheek cell experiment? | cell membranes |
| what is the main structural chemical in cell membranes? | phospolipid. |
| What is the role of cold alcohol in this extraction of cheek cells? | DNA won't dissolve in cold alcohol....so we can see the DNA. |
| Double helix | Shape of DNA. |
| Who discovered DNA? | Watson, Crick, Wilkins, and Franklin. |
| Where is DNA found in human cells? | nucleus and mitochondrion. |
| DNA function | -Genetic Continuity -Traits coded for DNA -Change - mutations |
| What is the function of methylene blue in cheek slide? | different pigments help make things show up. |
| how is a pap smear similar to cheek cell prep? | swab cells, put on slide, and check to see if they have dysplasia- growing in an odd fashion. |
| why couldn't we see more structures? | needed more dyes and fancier microscope. |
| Osmosis | water flow through cells. |
| Diffusion | particles move from high concentration to low concentration. |
| Isotonic | equal concentration. |
| Hypertonic | describes a solution whose solute concentration is higher than the solute concentration inside a cell |
| Hypotonic | describes a solution whose solute concentration is lower than the solute concentration inside a cell |
