BI 20B2
PHYSIOLOGY OF HUMAN CELLS
CREDIT POINTS 15

Course Co-ordinator: Dr Gordon McEwan

Pre-requisite(s): SM 1001, SM 1501

Co-requisite(s): None

This course introduces human physiology - the understanding of body function. The central concept, essential to physiology, is homeostasis - the maintenance of a relatively constant internal environment in a constantly changing external environment. This course (along with its partner BI25B2) will consider how this is achieved at cell and whole body level. The focus in this course will be on the roles of the nervous and endocrine control systems. Specifically, it deals with: the physiology of the cell with special reference to nerve and muscle; cell-cell signalling; neuro-endocrine integration and some aspects of endocrinology; membrane potentials and action potentials in nerve cells; reflexes; central nervous system control of movement; the physiology and pharmacology of the autonomic nervous system; transduction of sensory information by receptors and processing of sensory information by the CNS; the composition and function of blood including its role in immunity.
