Neurophysiology of Never Impulses
Introduction
The activities 3, 4 and 7 have been experimented. In inhibiting a Nerve Impulse, numerous physical factors and chemical agents can impair the ability of nerve fibers to function. In these activities they show this exactly. In these experiments, it showed the effects of various agents to nerve transmission. In testing the effects of ether, there will be a nerve that will be stimulated. The experiment is to see if ether has any permanent alteration in neural response of the nerve. I believe that it won’t because it has no lasting effect. Also, the experiments are to see if ether will have an effect on eliciting an action potential which I believe that it will make it difficult. Curare is a well known plant extract that South American Indians used to paralyze their pray. It blocks synaptic transmission by preventing the flow of neural impulses from neuron to neuron (Laboratory Manual). I believe that the effect of curare eliciting an action potential will lead to curare not being able to act on an action potential because it will block and slow down the stimulation from making any progress in the action potential. In experiment 7, which is testing the effects of Lidocaine, which is a sodium-channel antagonist that prevents sodium channels from opening, I believe that it will block the sodium channels from opening. And there will not be any effect on eliciting an action potential.
In the experiment of Nerve Conduction Velocity, it is the change in the membrane potential on the outside of the nerve that is being observed. The change that occurs here during depolarization will be so minuscule that it must be amplified in order to be visible on the oscilloscope. In this experiment, we will determine and compare the conduction velocities of different types of nerves. We will examine four nerves: an earthworm nerve, a frog nerve, and two rat nerves. The earthworm is the smallest; the frog nerve is a medium-sized myelinated nerve, Rat nerve 1 is medium-sized
