Subject Description

The principal objectives of this subject are: (i) to comprehend the terminology of physiology; the principles and essential information regarding the functions of different cell types and how they interact in organ systems; the control of these organ systems in the normal human being and the normal numerical values for those physiological variables commonly used as indices of disease (ii) to develop observational and organisational skills to use experimental techniques in analysing and evaluating physiological systems and document the findings reliably (iii) to appreciate the ranges of normality for physiological parameters and the factors which influence the significance of results obtained from investigating physiological systems. Major topics covered: Cell membranes, fluid balance and distribution in the body; cellular and whole body homoeostasis; excitable membranes; nerve and muscle cells; chemical neurotransmission; simple reflex organisation; autonomic nervous system; cardiac function; haemodynamics; distribution and regulation of cardiac output; control of blood pressure; whole body patterns of cardiovascular response.

Assessment

A 3-hour written examination at the end of the semester (85%). Assessment is also based on work undertaken in laboratory classes (15%). Where performance in laboratory classes is judged to be unsatisfactory, a student will be required to pass a supplementary oral or practical examination.
