Course Organization (brief summary, details below):
LECTURES, CLASS TIME, EVALUATION
I. Lecture Topic A. Drawing/Page Topic 1., 2... Information in Page During first viewing, minimize notes to get overview of lecture. Take more detailed notes on second viewing. Identify questions -- seek answers in book, in class, on WWW.
Video access... If absolutely necessary, I will put the lectures on a single DVD. Supply me with a blank writable DVD and I will make you a copy. Those trying but unable to view lectures in PSC; I have emailed the folks there asking that they make certain RealPlayer is available on those computers. Re. how to learn your PSC account username/password... Accounts are supposedly set up automatically for all students whose major is within the College of Science and Mathematics. Default username and password is probably your last name and your student ID number. If you have problems or questions, email "help@cosm.sc.edu", enter into the subject line "student with PSC account problems", and plead your case. Let me know if you continue to have such problems. Attendance. Close read of the syllabus will remind you I am empowered to deduct points for unexcused / uninformed absences. A final grade of 90 (an A) would now be reduced to 89 (a B+). I will take such attendance any time I feel class size is excessively low. I expect you to be in class when I am in class. If I am not in class, I expect you to be viewing and studying the lectures and course material.

PLEASE NOTE ERRATA SECTION BELOW. As I review the lectures I note inconsistencies. This is normal with any "new publication" though as annoying to me as it probably is to you. I am listing these below for your information as well as for correction the next time I record these. Acclimation vs. Adaptation Essay:CLICK HERE
back to top Sometimes seeing can help... Below are links to three Histology Web Sites back to top ERRATA: NOTED ERRORS IN LECTURES: Error in Introductory lecture (ca. 7:35 min). Not an error so much as science marching forward... When I made this lecture, the independent emergence of plant, fungi and animal lineages was not resolved (and me saying that the three lineages emerged simultaneously). However, currently, a divergence is thought to have occured first between a plant and a fungal/animal lineage, and later between the fungal and animal lineages. Each divergence would have been from a common ancestor. This suggests you are more closely related to a mushroom than you are to an ear of corn, and perhaps explains why one's ancestors might appear somewhat moldy in old pictures.... Error in Circ3 Lecture (ca. 8 min). Epinephrine (hormone) activates the beta-adrenergic receptor. Nor-epinephrine (neurotransmitter) activates the alpha-adrenergic receptor. At high concentrations, epinephrine also activates the alpha-adrenergic receptor. In my lecture, I reversed alpha and beta; all other aspects of this section (the effects that epinephrine and nor-epinephrine have) are correct. Alpha- and beta-adrenergic receptors are both GPCRs (as is the heart ACh receptor - also called a "metabatrobic ACh receptor" to distinguish it from the "nicotinic ACh receptor" of skeletal muscle which is an ion channel, not a GPCR). (Helpful Web site re. adrenergic receptors: http://www.elmhurst.edu/~chm/vchembook/663adrenergic.html) Error in Circ3 Lecture (ca. 13 min). In the discussion of Cardiac Mechanoreceptors. The mechanoreceptor in question INHIBITS ADH release (my lecture says they stimulate release). ADH (anti-diuretic hormone) is also called vasopressin, argenine vasopresssin and AVP; it is a 9 amino acid peptide hormone released from neuroendocrine cells in the posterior pituitary. ADH acts on Kidneys to REDUCE urine production by increasing the recovery of salts and water; this also results in an increase in blood volume and blood pressure. If Type B mechanoreceptors fire if blood volume increases and atria fill too quickly. Body responds by reducing blood volume. This would be accomplished by INHIBITING ADH release, resulting in the kidneys increasing urine production. (I said that Type B mechanoreceptors stimulate ADH release to decrease blood volume, which is incorrect). Error in Circ3 Lecture (ca. 18 min). In the discussion of the JGA-Renin-Angiotensin pathway, Renin stimulates the conversion of Angiotensinogen to Angiotensin. I say erroneously say the reverse, but you would recognize that Angiotensinogen (like pepsinogen and trypsinogen), is the precursor and angiotensin (like pepsin and trypsin) is the product. It is all in the name. Angiotensin acts on the kidneys and adrenyl gland to do the things I say angiotensinogen does. This pathway is discussed more fully in Kidney 3, which addresses regulation of the circulatory system. In somewhat more detail, renin is a protease and cleaves Angiotensinogen into two peptides, one of which becomes angiotensin-I; angiotensin-I is converted to angiotensin-II by phosphorylation (via a protein kinase). Angiotensin-II is the active form of the hormone. Error in Kid3 Lecture (ca. 12 minutes). Action of ANP. In this slide I say ANP acts on Distal Tubule; should have said Proximal Tubule, as I do in the following slide. Error in Kid1 Lecture (ca. 21 minutes). Talking about comparative osmolarities. In lecture I write that SW is 1000 Osm; should be 1000 mOsm (which I say).
Addition... Getting stronger by exercise? Two things... (1) You increase production of mitochondria and enzymes associated with glycolysis, to increase your ability to produce more ATP. (2) You activate myoblasts which differentiate and fuse to existing muscle fibers, contributing nuclei and producing additional contractile proteins. This is hormonally regulated. Useful web site:
I have linked a short discussion about what you should know re. Muscle Lectures 1 & 2: Notes on Movement (Mus1) and Electrical Properties of Cells (Mus2)

GENERAL ASSIGNMENT You are responsible to develop an understanding of all material discussed in the lectures and all the questions on the In Class Question sheets. You are responsible to participate in class exercises and to contribute to class discussions. Class discussion is to help all of you become familiar with all of the questions. QUESTION! INQUIRE! LISTEN!
My goal is to help you develop a fundamental knowledge of physiology that will empower you to continue learning for as long is you need or desire.
THIS COURSE IS DIFFERENT!!! Formal lectures are on-line videos (Real Stream). Class time will be used to develop and discuss answers to specific questions posed to students. See COURSE GAME below. Exam questions will be selected from among these problem sets; exam questions may be slightly altered.
Viewing the lectures... Each of you will find your own way. But... I suggest you view the lectures more than once. First viewing - look at all the lectures associated with the topic to gain an overview of material covered re. that topic (there are 6 topics). Take some notes, so that you can track your progress. Subsequent viewing ? take detailed notes. I have provided outlines of the lectures in the form of "Tables of Content". Remember questions that arise, and ask them in class.
Discussing the material with other students will strengthen you knowledge of the material.
Attendance is required. Grade penalties will be awarded unexcused absences (see below).
TEXTBOOK PROBLEMS??? I realize the text is expensive. Consider finding a copy on-line, perhaps at one of the following web sites.
Search the name of the book as:
If you really cannot get this book, any general physiology book may serve (not specific to humans), depending on your interest - clear this with me.
Save money, buy with a friend of buy used.
VIDEOS BEST VIEWED ON CAMPUS OR USING FAST INTERNET CONNECTION (Cable Road Runner or Telephone DSL) Videos can be viewed on any student computers in Biological Sciences, in the Library, and in most computer labs. You may need to provide your own headphones. IF YOU HAVE PROBLEMS, TELL ME ASAP!
ADJUST YOUR BANDWIDTH: If the video is not smooth (audio is OK but video seems like a slide show), adjust your Real Player's bandwidth. Do this by opening the Real Player, under "Tools" choose "Preferences". In "Preferences" choose "Connection". For both "Normal Bandwidth" and "Maximum Bandwidth" choose the highest setting that will work for you (10Mbps>T1>512>384>256>112). My Suggestion: set Maximum Bandwidth to 10Mbps. Set Normal bandwidth to 10Mbps. If this does not work, try the next lower setting for Normal bandwidth. Finish by clicking OK to save. This should give you a continuous movement video.
ABOUT PDF FILES: I've included some lecture notes in the form of .pdf files. To read these you will need Adobe Acrobat Reader.
You can get Adobe Acrobat Reader for free from Adobe's web site and following instructions: Click Here...
FINAL EXAM, OPTIONAL: The final will be cumulative over the entire term. Students may accept their grade based on the 3 mid-term exams. The final exam will review previous exams and students wishing to improve their grades are strongly encouraged to take the final exam. [NOTE: If you take the exam and turn it in, your exam score will be factored in to your final grade. If you take the exam (or part of it) and decide NOT to turn it in, your final exam will NOT be factored in to your final grade.]
Mid-term exams will be 100 points, and the final exam 200 points; thus each mid-term will contribute 20% and the final 40% of your grade (final = powerful points). If you choose the "no-final option", then mid-term exams will each contribute 33% of the FINAL COURSE GRADE. This final total will be lowered by penalty points (unexcused absence ? see LACK-OF-ATTENDANCE PENALTY below) or raised by bonus points (acceptable optional reports - see EXTRA CREDIT BELOW)

HOW MANY AND GRADING: Students may receive credit for a maximum of 5 (FIVE) essays. Essays will be graded on a 3 point scale: 3 points if strong and well supported; 2 points if weak, poorly supported or poorly referenced; 1 point if I can find any redeeming value; 0 point if I can find no redeeming value. These points will be added directly to your final percentage grades, a student scoring 75% on exams (C+) could see his or her grade raised 15 points to a 90 (A) if 5 excellent assignments are submitted. NOTE: I will be evaluating these assignments stringently. Be prepared to be asked questions (orally) about your effort.
WHEN DUE: Essays must be submitted within 2 weeks of their announcement (Note, I am relaxing this requirement - you may write essays on any posted questions up to the end of the course - 10/25/07). Questions / topics will be posted on the course web site.
WARNING: I do not generally accept research essays based solely on web pages (I do generally give credit for the initial submission unless they are overwhelmingly misguided). Although, a web page or a newspaper article may help you identify an interesting scientific paper or other reputable source. This exercise is an effort to direct you towards productive literature research, as well as to improve your writing / organizational skills. This exercise is also an effort to encourage you to further explore topics of personal interest.
BIG WARNING: I view plagiarism as a major and personal insult and deal with it harshly, as is permitted by the University. Don't do it. If you don't know what counts as plagiarism, ask.
Extra credit (and penalty points) will be applied AFTER an initial final grade is determined, thus moving a student's final grade upwards (or downwards) according to the points earned (or lost).
GRADES, BASED ON MID-TERM EXAMS WILL BE POSTED BY READING DAY ON "BLACKBOARD" TO ALLOW STUDENTS TIME TO DECIDE WHETHER OR NOT TO TAKE FINAL EXAM.
