WebStimulants and depressants affect the synapses between neurones in the nervous system: stimulants cause more neurotransmitter molecules to diffuse across the synapse depressants stop the next neurone sending nerve impulses – they bind to the receptor molecules it needs to respond to the neurotransmitter molecules. Tobacco and Smoking WebSep 4, 2024 · The place where an axon terminal meets another cell is called a synapse. This is where the transmission of a nerve impulse to another cell occurs. The cell that sends the nerve impulse is called the presynaptic cell, and the cell that receives the nerve impulse is called the postsynaptic cell.

At a chemical synapse, an action potential triggers the presynaptic neuron to release … WebWhat is synapse in biology class 11? Hint:Synapse is the junction between two neurons. The major function of the synapse is to transmit the impulses, i.e. action potential from one neuron to another neuron. Complete answer: Synapse is formed by the axon of one neuron ending on the cell body, dendrite, or axon of the next neuron.
WebThere is a small gap between the two neurones called a synapse. In order for an impulse to be generated in the next neurone, a chemical transmitter is released. This then diffuses across the small gap. Many drugs work by interfering with synapses. They may block or copy the action of neurotransmitters in certain neurones.
