WebAction potentials are crucial for transmitting impulses through nerve fibres, including synaptic. ... Cells in nervous tissue must be able to communicate with one another via electrical nerve impulses in order to perform all of these functions. Neurons or nerve cells are the cells in the neurological system that produce and conduct impulses. WebFeb 22, 2024 · Aα fibres (12-20 μm; 70-120 m/s) conduct impulses the fastest and serve skeletal muscles. Aβ fibres (5-12 μm; 40-70 m/s) have the second fastest conduction rate and are involved in vibration, pressure and tactile sensation. Aγ fibres (3-6 μm; 10-50 m/s) are the third fastest conductors of the A fibres and are a part of the proprioceptive ...

WebSep 16, 2009 · Joseph Erlanger sitting at the oscilloscope device that he and Herbert Glasser built to amplify and visualize nerve impulses, or action potentials, as they travel along a neuron. Using their device, Erlanger and Glasser discovered that different types of nerve fibres conduct impulses at different rates, which relates to their particular function. WebQuestion 6.
