Analysis of non-noradrenergic/non-cholinergic (NANC) transmission at single varicosities or swellings indicates that individual synapses possess different probabilities for the secretion of transmitter as well as different complements of autoreceptors and mixtures of post-junctional receptor … See more A neuroeffector junction is a site where a motor neuron releases a neurotransmitter to affect a target—non-neuronal—cell. This junction functions like a synapse. However, unlike most neurons, somatic efferent motor … See more In the peripheral nervous system, local junctional transmission was recognized in the late 1960s and early 1970s. Until then, all chemical neurotransmission was thought to involve synapses and the innervations of tissue were considered synonymous with … See more Non-synaptic transmission is characteristic of autonomic neuroeffector junctions.
