Question

brain communication
__________ part

• neurons are separated by a space (the __________)
• __________________________ (nt)
• nt released from the sending neuron travel across the synapse and bind to receptor sites on the receiving neuron, thereby influencing it to generate an action potential.
• some nts tell receiving neurons to \fire;\
• other nts tell receiving neurons to stop firing
• researchers have identified dozens of nts
• ex.: __________________________

Explanation:

1. The first blank refers to the section of neuron communication involving the space between neurons and signaling molecules, which is the Synaptic part.
2. The space separating neurons is defined as the synapse.
3. NT is the abbreviation for Neurotransmitters, the signaling molecules that cross the synapse.
4. A common example of a neurotransmitter is Acetylcholine (or other valid examples like Dopamine, Serotonin).

Answer:

1. Synaptic
2. synapse
3. Neurotransmitters
4. Acetylcholine (example; Dopamine/Serotonin are also acceptable)
