This unit examines in detail the mechanisms of nerve and muscle function, including behaviour of excitable cells; mechanisms of muscle contraction; muscle fibre types; metabolic processes in active muscle; neuromuscular fatigue; and muscle plasticity.  Students are also introduced to current research techniques in nerve and muscle physiology.

RBM3264

Prerequisites

RBM2800 - Cardiorespiratory and Renal Physiology

Learning Outcomes

On successful completion of this unit, students will be able to:
  1. Critically reflect on the experimental evidence describing ionic movement, the action potential and its synaptic transmission at the neuromuscular junction;  
  2. Interpret the basic chemical and mechanical steps of muscle contraction, including the concepts of twitch, recruitment and tetanus, and the force-velocity relationship;  
  3. Discriminate between the structural and functional properties of skeletal, cardiac and smooth muscles;  
  4. Interrogate the regulation of intracellular calcium and its effects on muscle fatigue and damage processes;  
  5. Investigate muscle fibre types, metabolism and fatigue with different exercise intensities;  
  6. Analyse the immense plasticity of skeletal muscle and produce a coherent scientific argument on a current topic of interest in skeletal muscle in health, disease and ageing; and  
  7. Experiment according to ethical protocols on both animal tissue and human subjects to illustrate basic properties of nerve/muscle function.
