Unit description
This unit follows on from BIO257 and BIOL247. We will investigate the interaction of the renal and respiratory systems in the control of body pH. The next topic is the control of blood pressure leading to a discussion of hypertension and exercise. We continue with endocrinology discussing signal transduction and messenger pathways, and the role of hormones in the regulation of plasma potassium, calcium and glucose concentrations. A discussion of neuroendocrine systems and function of thyroid, sex, growth, mineralocorticoid and glucocorticoid hormones leads into a discussion of stress and the stress hormones. As obesity is currently a major threat to human health we will consider energy balance and the neurological basis for homeostatic and hedonic control of appetite before investigating other factors involved in weight control including genetics, foetal programming, protein leverage and the gut microbiota. The final two lectures will be on the neurobiology of the reward systems involved in hedonic eating and drug addiction. Practical classes make use of computer-assisted learning, as well as laboratory experiments. We will measure physiological parameters such as blood pressure during exercise, acid and base in the urine and stress hormones in the saliva. In these classes students will act both as investigators and experimental subjects.

Assignment on the effect of exercise on the cardiovascular system
In this assignment the exercise practical will be written up in the form of a scientific paper with a title, aims, methods and results sections. The discussion session will be replaced by a series of questions that are focussed on the changes in cardiovascular function underlying the increased muscle activity during exercise.
Due: 19/9/2014
Weighting: 10%
This test will include 30 multiple choice questions to be completed in 40 minutes. All the material in llectures 1-12 and the material presented in the practical classes will be included in the test.
Due: 12/10/2014
Weighting: 10%
The essay is of 2,000 words and you have a choice of 13 topics. Emphasis is to be on physiological aspects of each topic.
Due: 17 & 24/10/2014
Weighting: 10%
Your seminar topics will be the same as your essay topic. You will present your seminar as part of a team of three students. All three can present part of the seminar or there could be only one presenter as long as all team members contribute equally to the preparation. All three members will be expected to answer questions on the topic at the end of the seminar.The main criterion for marking will be the quality of presentation although the physiological content will also be considered. You will have 15 minutes to present your seminar and 5 minutes of question time.
Due: 2/11/2014
Weighting: 5%
We will carry out experiments to determine the effect of different types of exercise on heart rate and arterial blood pressure in different individuals. Using our results we will identify the underlying causes of changes in BP during exercise. We will also consider the regulatory systems controlling BP during exercise. Each student will write up a report of 750 words on the results and significanct findings of their experiments.
Due: Examination period
Weighting: 60%
The exam is a three hour paper 33% of the marks will be for multiple choice questions, and the rest from short answer questions (a paragraph or dot points or a diagram).There will be some choice for the short answer questions. All the lecture and practical material is examinable. A non-programmable scientific calculator will be required in the exam.

There will be two lectures each week and one practical class or tutorial session. Lectures are at 4 pm on Monday in W6B 336 and 9 am on Friday in E6A 133. Pracs are at 10 am and 2 pm on Friday in F7B 105 and F7B 110.
Practical sessions for external students will be held on Saturday 6th September & Sunday 7th September and on Thursday and Friday the 2nd & 3rd October. Note that the external classes will only run if sufficient students chose this option.
Unit material and TextbooksThe textbook for this unit is “Principals of Human Physiology” 4th edition by Cindy L Stanfield, published in 2011 by Pearson. However, much of the material covered in BIOL376 is not available in text books. Where this is the case I have included relevant references in the lecture graphics.
iLearnYour iLearn site will contain the unit outline, lecture graphics, practical manual, a link to Echo 360, announcements and discussion areas. Later marks for in semester assessments tasks will be added. Please check this site and your student email regularly.
