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.
