Passive and active mechanisms determine the net, muscle force. The latter is associated with the number of muscle fibers excited, and thus motor units recruited, and the rate at which muscle fibers are excited. The first three slides provide an approximate...
The muscle fibre conduction velocity (CV) is the speed with which action potentials travel along the muscle fibres. Owing to its sensitivity to events of applied interest (e.g. muscle fatigue), CV earns relevance for the study of the neuromuscular system. The...
Innervation zones, where end-plates distribute within striated muscles, can be identified with arrays of electrodes. For this to be possible, electrodes and muscle fibres must reside in parallel planes. Innervation zones are identified where two, consecutive action...
This powerpoint presentation contains 11 animations. Slide 1 illustrates the generation of the muscle fiber action potential and how it contributes to the generation of electromyographic signals. Slides 2-3 illustrate why two electrodes are commonly used to record...
Understanding how action potential propagation in muscle fibres can be assessed from surface EMG This material was prepared with the goal of illustrating how surface EMGs convey information on the propagation of action potentials. Analogy is made to the wave...
