Overview

This course takes the integrative function of major organ systems as its main theme. We begin by considering the scientific method in physiology and how the human body copes with the challenges of maintaining homeostasis. We then focus on four specific organ systems - the cardiovascular, respiratory, gastro-intestinal and renal systems. The student will learn how these systems function during health and disease, and how they interact with one another. Special emphasis is placed on the measurement of organ function and pathophysiology. Instruction is also provided in experimental design and measurement of cardiorespiratory variables. Lecture and case-study material is accompanied by the use of a microcomputer in data capture and analysis and a problem-solving project. The course consists of 4 lectures and 1 project/laboratory session per week, and is examined by continuous assessment of course work and a 3-hour written exam.

Structure

3-4 one hour lectures per week and 1 all day practical every week.

Assessment

1st Attempt: 1 three-hour essay examination (67%) and in-course assessment (33%). Continuous assessment comprises: 2 laboratory reports, 3 case study exercises, 1 literature-based project (comprised of an individual abstract, a group poster and a peer assessment mark).

Resit: 1 three-hour essay examination (67%) and previous continuous assessment (33%).

Formative Assessment

- Case-study exercise with feedback in preparation for summative assessments.
- Practice exam questions on MyAberdeen.
- Problem-solving sessions.

Feedback

- Practical reports and case studies will be marked with written comments.
- Tutorial/practical sessions will provide feedback on course content.
- Model answers of all assessments will be posted on MyAberdeen.
- Students given informal feedback from wider school during poster presentation session.
- Students also given peer feedback.
- Students also given written feedback on group poster.
- Students also given oral fedback if requested at each weekly practical/project session.

Overview

Epithelial transport is essential for the maintenance and propagation of life. In this course you will explore the features of transporting epithelial cells which make them uniquely suited for mediating the controlled, directional passage of ions, nutrients and water across the walls of the alimentary, renal, respiratory and reproductive systems. The importance of these processes to the normal physiological function of these organ systems is reflected by the pathophysiological symptoms which manifest themselves when transport regulation breaks down. For example, infectious diarrhoea occurs as a result of excessive intestinal fluid secretion and accounts for more than five million child deaths per year in developing countries. At the other extreme, the most common genetic disease of the developed world, cystic fibrosis, is caused by a failure of epithelial tissues to secrete any fluid at all resulting in malnutrition, infertility and ultimately, respiratory failure and death. The course will initially examine the common features of transporting epithelial cells and the technologies available for their study. Following on from this, the role of epithelial cells in the kidney, gastrointestinal tract, reproductive tract and respiratory system will be examined in detail. Emphasis is placed on understanding the cellular transport mechanisms required for the normal physiological function of these systems in health. Where insight into these processes has been enhanced by the study of disease models, these will be highlighted.

Structure

3 one hour lectures per week and 1 all day practical every week.

Assessment

1st Attempt: 1 one and a half hour essay examination (70%) and in-course assessment (30%).
Continuous assessment comprises: 1 laboratory report, 1 oral presentation of a research paper.

Resit: 1 one and a half hour essay examination (70%) and previous continuous assessment (30%).

Formative Assessment

- Assessment forms with grading criteria discussed in full with class prior to completion of laboratory report and oral presentation exercises.

Feedback

- Practical reports will be graded with structured written comments.
- General class feedback session following return of graded reports.
- Written and verbal feedback provided following grading of oral presentation exercise.
- General class feedback session on oral presentation exercise.
- Exam information session delivered with advice for successful study.

Overview

This course considers development of the nervous system in a broad context. Topics include the initial establishment of the nervous system in an embryo, the birth and migration of nerve cells, nerve growth and guidance mechanisms, synapse formation, and development of the eye, including how it is "wired" to the brain. Discussion of nervous system plasticity encompasses stem cells and regeneration following injury or disease (e.g., spinal cord injury, stroke).

Structure

14 lectures plus student-led presentations. Performance is assessed by an independent written summary of a group presentation topic, an essay, and a 2-hour written exam.

Assessment

1st Attempt: 1 two-hour written examination paper (70%) and in-course assessment - group work (15%) and essay (15%).

Notes

The practical work required in this course may pose difficulties to some students with disabilities. If this arises alternative arrangements will be made. Any student wishing to discuss this further should contact the School Disability Co-ordinator.

Overview

A ten week research project is undertaken and the student learns laboratory and literature research techniques and presents a thesis. The thesis is defended in an oral presentation. Students gain extensive experience of data acquisition and databases using microcomputers.
