  1. Bio 342Human Physiology

  2. Oscar Pistorius of South Africa

  3. A physiologist asks… • How do things work in the human body? • How is stability achieved? • What are the causes and consequences of disruptions of stability? • Physicians ask “How can stability be restored?”

  4. Theme of this course: Homeostasis Disturbed homeostasis Aging, infection, injury

  5. Group advising for premed studentsMonday, Sept 3Evening 1st day of classes • For those interested in medical school, an advisor will present and answer questions at the following times and locations: • Freshmen: two sessions either from 8-8:30 pm or 8:30-9:00 Advisor Dr. Spivey, meet in RMSC 122 (The Pit)and bring your course schedules. • Sophomores: 9:00-9:30 pm Advisor Dr. Moss, meet in RMSC 122. • Juniors: 8:30-9:00 pm Advisor Dr. Moeller, meet in RMSC 121. • Seniors: 9:00-9:30 pm Advisor Dr. Moeller, meet in RMSC 121. • For those interested in Physician Assistant (PA) programs you can meet with your PA advisor Dr. Moss in RMSC 121 at 8:00-8:30 pm (all years) • For those students interested in graduate programs in biology and allied fields we will have an interest/advising meeting in the near future.

  6. BIO 342 HUMAN PHYSIOLOGY • PHYSIOLOGY: The study of the function of cells, tissues, organs, and organ systems. • THE TEXT: Widmaier et al. 20011 (12th ed.) • Chapter 2-5 review of other courses • Using your textbook • Using chapter questions from Website

  7. The Syllabus (on the course websitehttp://webs.wofford.edu/davisgr/bio342/)and Moodle Site for Grades and Electronic Assignments • Office & cell phone numbers • E-mail (davisgr@wofford.edu) • Lecture topics by week • Text chapters in parentheses • Read in advance of lectures

  8. LABORATORIES • May shift topics due to availability of animals • One Lab Report in the form of abstracts • very concise, based on lab data • Incorporate statistics • With revision and resubmission • No separate lab tests; lab material included on lecture tests

  9. GRADING • 3 lecture tests = 60% • multiple multiple choice (choose all correct answers) • Some short answer in the space provided • Rarely fill in the blank • Sometime create or complete graph or diagram • discussion question(s) from a list • Cumulative final exam = 20% • Other work = 20% • Abstract = 10% • 1 Question Quizzes (1QQs) = 10%

  10. Honor Code • All worked is “pledged.” • Issues of plagiarism to be handled by the Honor Court. • Work together, but submit your own work.

  11. ODDS AND ENDS • Limited use of electronics in classroom & lab • Only for class/lab-related activities • NO FOOD or DRINKS in Lab • BE ON TIME, READY TO GET TO WORK • DON’T ASK ABOUT LENGTH OF LAB • BE READY TO START ON TIME

  12. Study Questions & Quizzes • Questions provided for each chapter (On the website!) • Read the book and answer the questions PRIOR to class meeting • Class time is used to deal with problematical topics and reinforce the major concepts • Be ready for 1QQs

  13. Study Questions & Quizzes • Rationale for this format: • See what Dr. Davis thinks you ought to emphasize • Writing helps to consolidate memory and recall • Greater effort results in better retention and understanding • Students are engaged learners • Able to cover more information • Improve MCAT, DCAT and GRE scores

  14. 1QQ # 1 Name on top edge, back side of paper Answer on blank side of paper. Answer one of the following: • The 200+ cell types in the human body can be classified into one of 4 cell types or tissue types. List the 4 types and their distinguishing characteristics. • List the 4 modes of heat exchange. • What is the difference between an organ and a tissue?

  15. A Taxonomy of Cognitive Skills for Developing Student Assignments and Assessments* *SC SDE (Pat Mohr). Adapted from Lorin W. Anderson, David R. Krathwohl et al (Eds.) A Taxonomy for Learning, Teaching, and Assessing: A Revision of Bloom’s Taxonomy of Educational Objectives 2001; modified by Ellen Goldey, Wofford College, to incorporate “Biology in Bloom,” Crowe et al., 2008, CBE – Life Sci Edu., 7: 368-381. **HOCS = higher order cognitive skills, LOCS = lower order cognitive skills.

  16. More stuff • Arrive early for lecture and lab • Pay attention (no cell phones, email, Facebook, etc. during lecture or lab) • Take notes on what is said….don’t wait for boardwork. • Powerpoints usually posted AFTER lecture • Drop by the office for a visit! • Complete the Personal Information Sheet on the Moodle site and submit it electronically to Moodle.

  17. Chapter 1 and parts of 16 • Tissues • Organs • Organ Systems • Homeostasis • Negative & positive feedback, acclimation • Two detailed examples: Thermoregulation and Glucose Homeostasis

  18. Genetics & Development Cell & Molecular 200

  19. Histology Name and organ and verify it has all 4 tissue types.

  21. Cell types (1) • Hepatocyte • Cardiac myofiber • Type II pneumocyte • Purkinje fiber (heart) • Erythrocyte • Enteroendocrine cell • Simple cuboidal cell of the proximal renal tubule • Principal cell of the thyroid gland • Endothelial cell • Fibroblast • Osteocyte • Lactotroph • Acinar cell of pancreas • Beta cell of Islet of Langerhans • Schwann cell

  22. More cell types (2) • Rod cell of the retina • Leydig cell • Hair cell of cochlea • Smooth myofiber of arteriole • Mast cell • Unilocular adipocyte • Alpha motoneuron • Gamma motoneuron • Retinal ganglion cell • Megakaryocyte • Satellite cell (ganglion) • Astrocyte • Dorsal root ganglion cell • Merkel cell • Myoepithelial cell of salivary gland

  23. Even More Cell Types (3) • Parietal cell of stomach • Chief cell of stomach • Paneth cell • Podocyte • Juxtaglomerular cell • Cell of the macula densa • Chromaffin cell of the adrenal medulla • Parafollicular cell of the thyroid • Cell of the collecting duct in the kidney • Secretory cell of the zonaglomerulosa in adrenal cortex • Secretory cell of the zonal fasciculata in adrenal cortex

  24. The Human Body:A Society of Cells • Imagine you are a cell. Ask yourself: • Which type of cell am I? (Epithelial, Connective, Nervous, or Muscle) • What do I do for myself? (What are my special characteristics and functions?)  • What do I do for the person in whom I reside? (What are my contributions to the whole organism? To homeostasis?)  • What do I need simply to survive? • In what ways to I depend on other cells? • What governs my actions?  • How long will I live? • What would happen to the organism if I along with all the other cells of my type were to fail to function properly? Check Moodle Site to find which cell type you are.Submit your answers to the Moodle Site by Wednesday 9 am. Bring a printout to class on Wednesday.
