Course unit overview
Excitable cells - cells which respond to stimuli by producing an electric current - are key to the function of our muscles and nervous system. You will learn about the structure and function of these cells, what makes them important and the techniques used to study them.

Aims
To consider the major concepts underlying the basis of cell excitability, the structure and function of excitable cells and their contribution to muscle and nervous system function.
Learning outcomes
Employability skills
Problem solving
Numerical problems are a key component of the coursework
Syllabus
Overview. Gross organization of the nervous system. History of neuroscience. Cellular organization of the nervous system. The cytosol, extracellular fluids, membranes. The proteins - ion channels, pumps and transporters. Diffusion, permeability, electricity. Origin of resting membrane potentials. The action potential. Transmission and saltatory conduction. Electrical synapses. Chemical transmission. Electrophysiological techniques such as patch clamping. New research techniques such as fluorescent probes and optogenetics. An introduction to sensory biology, including how the eye functions. A model synapse - the neuromuscular junction. Gross organization of musculature. Cellular structure of muscle. Excitation-contraction coupling in muscle cells. Disorders of the nervous system: neurodevelopmental disorders; Neurodiversity. Simple nervous systems: invertebrate learning. Vertebrate nervous systems: learning language and the brain.

Assessment methods
Written exam | 90% |
---|---|
Other | 10% |
90% awarded for the unit examination which will consist of 50 multiple choice questions, in the semester 2 examination period. 10% awarded for online summative multiple choice question-based assessments.
Feedback methods
Feedback on coursework MCQs will be provided via the Blackboard MCQ system. After the exam results have been released we will also make the unit exam paper available as a Blackboard quiz (with feedback). Formative feedback will be available via revision reversions of summative assessments and an online version of last year’s exam paper.
