WebSynaptic transmission. Neurones interact with other neurones and with muscles. At the end of the axon of a neurone there is a widening called an end bulb (several in an axon terminal). There is a gap - usually called a synapse - between this and the next cell. WebBotulinum toxin, or botulinum neurotoxin (BoNT), is a neurotoxic protein produced by the bacterium Clostridium botulinum and related species. It prevents the release of the neurotransmitter acetylcholine from axon endings at the neuromuscular junction, thus causing flaccid paralysis. The toxin causes the disease botulism.The toxin is also used …

In the nervous system, a synapse is a structure that permits a neuron (or nerve cell) to pass an electrical or chemical signal to another neuron or to the target effector cell. Synapses are essential to the transmission of nervous impulses from one neuron to another. Neurons are specialized to pass signals to individual target cells, and synapses are the means by which they do so.
