Nerve activates contraction
... Synapses can be electrical or chemical. Ions carry information in electrical synapses. In chemical synapses, a neurotransmitter is released by the presynaptic neuron at the junction when the axon depolarization (message) reaches the synapse. This neurotransmitter diffuses across a space (cleft) to t ...
