WebAt a synapse, one neuron sends a message to a target neuron—another cell. Most synapses are chemical; these synapses communicate using chemical messengers. Other synapses are electrical; in these synapses, ions flow directly between cells. At a chemical synapse, an action potential triggers the presynaptic neuron to release neurotransmitters.

WebThe meaning of TWITCHY is marked by twitches or jerking movements : tending to twitch. How to use twitchy in a sentence. WebADVERTISEMENTS: When multiple stimuli are delivered in quick succession to produce summation of twitches, the muscle gets tetanized, i.e., it remains contracted and does not relax. If the stimuli are spaced sufficiently close, the individual peaks fuse to produce a complete tetanus and the contraction reaches a near-perfect plateau.
