Description
Bio 269 Lab Exam 1 Study Guide Authored by Drs. Phares and Casotti In General The exam will be a mixture of multiple choice, short answer, and graphing questions that will test your knowledge of physiological principals, your ability to apply scientific methods, and your ability to think critically. The labs covered are: the introductory lab (graphing ), Psychophysiology III, Hematology, Electrocardiography III. You may be asked to: Draw a properly labeled graph given data or an experimental design; Design an experiment given a question; Design additional experiments given a question and results of an initial experiment; Relate experiments done in the lab with theory learned in Dr. Casottis lectures. You should bring an eraser and a ruler to the exam. Remember to keep the hypothesis being tested or goal of the study in mind so that your graph or experiments are relevant! Describe means to tell us how something looks or appears. Explain or Why means to tell us the underlying physiological mechanism(s) . You should know how the physiology works in detail for all of the experiments you conducted in the labs. The Specifics 1. Review the introductorybackground paragraphs of each lab. Theyre pretty terse so you may want to refer back to your lecture notes andor the textbook to clarify or expand when necessary. 2. Pay special attention to any terms or sentences highlighted by bold typeface. 3. Review the definitions of , and be able to identify independent and dependent variables. X axis: INDEPENDENT VARIABLE ; Yaxis:DEPENDENT VARIABLE . 4. What does the GSR measure? What are its units? How is the GSR related to the autonomic nervous system activity? How is the GSR affected by stressful stimuli. What happens to the GSR recording and its underlying physiological processes when the stressful stimulus is removed? 5. Of what physiological process is skin temperature an indicator? How is skin temperature related to the autonomic nervous system? Be able to describe and explain how is skin temperature affected by stressful stimuli? 6. Be able to describe the changes that occur to pulse rate and depth when the autonomic nervous system is up regulated. 7. Be able to identify the 5 different white blood cells: basophil, eosinophil, neutrophil, monocyte, and lymphocyte. What are their relative abundances? (Which is mostleast abundant?) 8. Be able to read a hematocrit. What does it represent? How is the information used? 9. Know the equations and how to do calculations for RBC count, WBC count, MHCH, MCV. Know the units in which these values are expressed and what, as noted in the lab manual, their normal values are. Tip: for MHCH MCV, learn the full title, not just the abbreviation. 10. Know how to determine blood type for the ABO and Rh systems. Understand the differences between the antigens expressed on the plasma membranes of RBCs, the antibodies that circulate in the plasma, and antisera used for probing bloodtissue types. 11. What does agglutination mean? What is its significance? 12. Describe means tell me what an object (organ, tissue, trace) or phenomenon (heart sounds) looks 1 of 2
