By enrolling in this unit, students are electing to combine their marks (subject to achieving a minimum mark of 45 per cent in each of the components) from the separate semester units Physiology 240 and Physiology 250 into a single final mark.
Students should consult a Department of Physiology course adviser to discuss the advantages of an enrolment in Physiology 200. See also Science Courses Booklet 2001 for further details.
This unit is an introduction to the properties of single cells of vertebrates. It begins with a consideration of cells in general and the special properties of cell membranes for the transport of substances and the transduction of electrical and chemical signals. Students learn how the many functions of cells are regulated by signals passed from one cell to another to control cell growth, division and movement. They also learn how messages control gene expression, cell proliferation and organ development. Consideration is given to the principles governing the shaping of cell masses into organ systems and ultimately, into whole organisms.
This unit continues with the study of the way living organisms work--with humans as the central example. The functioning of all the major organ systems is covered including the nervous, respiratory, renal, gastrointestinal, reproductive and heart and circulatory systems, as well as the nervous and hormone regulation of their functions. Consideration is also given to the integration of the functioning of organ systems. Students are given the opportunity to develop their oral communication skills through short tutorial presentations on selected topics.
Those students without Physiology 240 should read chapters 2 to 4 of Human Physiology by L. Sherwood before beginning the unit.
This is an advanced unit in cell physiology including membrane transport processes, neurophysiology and muscle physiology. Students majoring in Cell Physiology must take this unit. Lectures and laboratories are arranged in modules, each comprising supervised experiments with reading lists and a written assignment. Major emphasis in laboratory classes is given to hands-on investigative approaches to the solving of scientific problems using isolated cells, tissues and whole animal preparations. Assessment is by laboratory reports, assignments and a final examination.
This unit is distinctive from other physiology units as it gives students training in laboratory techniques for obtaining animal material for experimental purposes. It also utilises spreadsheets in data analysis, presentation and simulation of complex biological systems.
This unit contains a strong component of laboratory experiments in which students learn how physiological mechanisms provide integrated control in man and other mammals. A major objective is to develop an understanding of the links between cell physiology and the functioning of major organ systems, focusing particularly on the cardiovascular and respiratory systems, metabolism and temperature control. The homeostatic mechanisms of control to meet the varying needs of the body are considered from a viewpoint of exercise and from the effects of system failure in disease. Assessment is by laboratory reports, assignments and a final examination.
This unit develops further students' laboratory techniques for physiological measurement in experimental animals and humans. Students also use simulation software to investigate the behaviour of complex systems.
