Interpretation:
The way how a nerve impulse is passed from one neuron to another has to be explained.
Concept Introduction:
Neurotransmitters: Neurotransmitters are chemicals that transmit messages from the nervous system to the target cell. They are the chemical messagers where the electrical signal from the nervous system is travelled from one neuron to another to reach the target cell.
Presynaptic neurons produces neurotransmitters which are stored in the small pockets of presynaptic neurons called vesicles from where the neurotransmitters are released according to the need. After neurotransmitter completes its job, it is immediately removed from the cleft of synapse for preparing the presynaptic neurons to get another impulse.

- Explain the role of neurotransmitters in the transmission ofa nerve impulse across a synapse.arrow_forwardMultiple sclerosis (MS) is a disorder that causes the destruction of myelin sheaths surrounding neurons. People with MS display many symptoms, including slurred speech, double vision, and poor muscle coordination. What is the direct effect of MS on nerve impulse transmission? Select one: The movement of impulses along neurons is slower than normal. Dendrites cannot be stimulated by acetylcholine, therefore impulses are not generated in neurons. The threshold level of stimulation for neurons is greater than normal. Axons cannot sectete acetylcholine, therefore impulses are not able to travel across synapses.
