Experiments in Human Neuro-Muscular Physiology (v2.0)

Producer: COACS (Commercial and Academic Services), Ltd.

This package, developed at the University of Aston (UK), introduces the student to some of the apparatus (oscilloscope, stimulator) and the experimental techniques used to examine resting potential, action potential and nerve conduction. The student looks at intracellular recording, extracellular recording and how to make recordings from a conscious human. The package is split into three sections: 1. Simulator and oscilloscope - the student can vary the controls of a simulated stimulator (frequency of stimulus, delay, output) and oscilloscope (timebase, Y amplifier gain) to find out what each of the controls does; 2. Recording bioelectric potentials - the student looks at the ionic mechanisms underlying resting and action potentials in excitable cells, then goes on to look at how to record resting and action potentials in excitable cells using intracellular electrodes and extracellular microelectrodes; 3. Experiments on a conscious human - the student looks at the experimental set-up used to measure impulses in a conscious human, then goes on to examine: a. How increasing stimulus strength to the nerve affects the amplitude of muscle action potentials and muscle contraction; b. Summation of muscle contraction; c. Nerve conduction velocity. The student also looks at the relationship between initiating muscle contractions voluntarily and initiating muscle contractions by artificial stimulation of the nerve.
