When you are very nervous, your mouth is dry and your heart is racing. This is most likely due to stimulation by

Sympathetic division of the autonomic nervous system

The signal that crosses a synapse is stopped when

The neurotransmitter is enzymatically broken down/ transported back to signaling cells

During transmission across a typical chemical synapse

Neurotransmitter molecules bind to receptors in the receiving cell's plasma membrane

The autonomic nervous system

Regulates the internal environment of the body

The enteric division of the autonomic nervous system consists of neurons in the digestive tract, the gallbladder, and the


The gap between the transmitting and receiving neurons in a chemical synapse is known as the

Synaptic cleft
