Title: if the average neuron conduct an impulse at the rate of 1meter/sec & a substance covering myelinated neurons? Post by: o2982794@rtrt on May 9, 2013 allows them to transmit at the speed of 100 meter/s, what is the substance called?
Title: if the average neuron conduct an impulse at the rate of 1meter/sec & a substance covering myelinated neurons? Post by: ikim on May 9, 2013 Not sure if this is what you are looking for if I misunderstood the question. Hope this helps though!
Myelinated nerves are covered in myelin. Myelin is made in the central nervous system by oligodendrocytes and in the peripheral nervous system by Schwann cells. It allows neurons to conduct impulses much faster via "saltatory conduction" where the impulse sort of 'skips' along the nerve and only fires action potentials at unmyelinated spots called Nodes of Ranvier. |
