Document Summary
When it comes to chloride, which it is an inhibitory ion, it can cancel out the signal. Some neurons have chloride pumps which pump chloride out of the cell, where there is more. Some neurons actively transport chloride inside, making it less likely that the neuron is going to reach threshold. however, if you open sodium channel so that it goes in, chloride cancels out sodium positive ions. Hence, it is more likely to re action potential more pain. If we had no calcium ions outside of the cell, we would have no neural function. When we think about the nervous system, there are many other parts other than the brain and the spinal cord. When we think about information coming out = efferent. All efferent responses are carried out using only 2 neurotransmitters: Each nt harmony different receptors and each target organ can have a different response. All functions from saliva secretion to punching someone use these two nt.
