A synaptic knob is a small protuberance that forms on the end of a neuron when it is stimulated. Synaptic knobs allow the neuron to communicate with other neurons by releasing neurotransmitter molecules. These molecules help to create an electrical signal that sends information from one neuron to the next. Synaptic knobs are an essential part of the nervous system, as they are necessary for neurons to communicate with each other and ultimately help the body to function.
