Neuroeffector junctions are varicosities where motor neurons release neurotransmitters to non-neuronal target cells. These junctions can be observed along the axon.
The motor nerve varicosities RELEASE neurotransmitters onto smooth muscle cells.
There are many varicosities along the axons of the neurons that feed smooth muscle cells.
When autonomic neurons are stimulated, varicosities release neurotransmitters along their axons.
These neurotransmitters then diffuse through the interstitial fluid to interact with receptors in the smooth muscle cells.
