Module summary

Module code: BIOC0578
Level: 5
Credits: 15
School: Engineering and Science
Department: Science
Module Coordinator(s): Abigail Rickard

Specification

Aims

• To develop students' understanding of the roles and limitations of homeostatic control and regulation;
• To examine the factors which contribute to the integrated control of representative examples of different physiological systems

Learning outcomes

On successful completion of this course a student will be able to:

Learning Outcome
1 Explain the inter-relationships existing between the anatomy and physiology of organ systems
2 Discuss how physiological and biochemical systems interact to maintain the stability of the internal environment
3 Explain how regulation of internal physiological parameters is related to changes in the external environment
4 Analyse, synthesise and summarise information and to present a critical review thereof

5 Design, plan, conduct and report on investigations, obtaining and analysing data
using appropriate techniques (working individually or as a group)
6 Undertake investigations in a responsible, safe and ethical manner;

Skills Learning Outcomes:

• Obtain and integrate knowledge from a range of text and electronic sources
• Reference / cite work appropriately
• Use electronic systems as an information source and communication tool in a critical manner Develop an adaptable, flexible, and effective approach to study and work

Indicative content

Endocrine and neural systems: Transmission of information by electrical and chemical signals; synaptic events; transmitters; receptors and signal transduction; information processing; control of hormone action and secretion; neuro-endocrine co-ordination; pituitary-hypothalamic relationships. Cardiac and respiratory systems: the cardio-vascular system, baroreceptors and medullary control centres; cardiac and vascular contraction; ventilation of the lungs; chemoreceptors and the medullary inspiratory centre; transport of oxygen and carbon dioxide in blood. Fluid and solute regulation by the kidney: Renin, aldosterone and the control of sodium reabsorption; ADH/vasopressin and the control of water reabsorption; salt balance, water balance and blood pressure; extra-cellular hydrogen and bicarbonate ion regulation and the control of pH. Thermoregulation: The hypothalamic 'set-point'; avenues of heat loss and gain; shivering and non-shivering thermogenesis; acclimation and acclimatization of thermoregulation; pathological and adaptive hypothermia. Immunological Co-ordination: Types of immunity; innate and specific responses; antigen-antibody interactions; complement; phagocytosis; immunisation


Teaching and learning activity

This course will consist of lectures and incorporated practicals. Lectures will be used to review a variety of complex regulatory processes which occur in physiological and biochemical systems. Online support is integrated into the course. Practicals will enable students to become familiar with a wide range of different techniques used in physiological investigation and will train them to present and interpret scientifically the results of their work.

Assessment
