What happens when a nerve impulse reaches the end of a neuron?

Cellular communication

Explanation:

At the end of a neuron, there is a space called the synaptic junction that helps it communicate with another neuron or organ in order to produce a response. When the impulse reaches the end of a neuron usually called the axon terminal, it causes the opening of voltage gated ion channels that causes the influx of ions inside the cells. This in turn will cause synaptic vessicles that contain neurotransmitters to move towards the membrane of the axon terminal and fuse with the membrane then open up to release the neurotransmitters into the synapse (space between the 2 neurons). When this happens, the voltage gated channels close. The neurotransmitters then bind to ligand receptors on the second recieving neuron that cause it to produce an effect like stimulate an organ or produce an impulse . After using up the neurotransmitters, they can be recycled or broken down into metabolytes that are used up by the cell.

stimulus is a change in the environment that causes an organism to react. the response is the reaction to the stimulus. some examples of stimuli for zebras are drought, to many predators, and bad feeding grounds such as dead grass or plants. zebras respond to stimuli just like all other living organisms
