Following a stimulus, explain how the opening of sodium ion channels affects the potential difference across a neurone cell membrane. . Describe and explain the movement of sodium ions if the potential difference across a neurone cell membrane reaches the threshold level. .
The Synapse. A junction that mediates information transfer from one neuron:. To another neuron, or. To an effector cell. The Synapse. Presynaptic neuron—conducts impulses toward the synapse. Postsynaptic neuron—transmits impulses away from the synapse.

Sympathetic. SYSTEM. The . Autonomic. . N. ervous. . S. ystem. The . autonomic nervous system (ANS). regulates the functions of our internal organs (the viscera) such as the heart, stomach and intestines. The ANS is part of the peripheral nervous system and it also controls some of the muscles within the body. We are often unaware of the ANS because it functions involuntarily and reflexively. However, some people can be trained to control some functions of the ANS such as heart rate or blood pressure. .
