<reasoning>

Identify chemical messengers

GABA, dopamine, and norepinephrine are chemical substances released by neurons to transmit signals across synapses. These molecules are classified as neurotransmitters.

Define the synaptic gap

The microscopic space between the axon terminal of a sending neuron and the dendrite of a receiving neuron is called the synaptic cleft.

Analyze glial cell functions

Glial cells are non-neuronal cells in the nervous system. They are active contributors to nervous system function, exist in several distinct types (such as astrocytes, oligodendrocytes, and microglia), and perform diverse, specialized roles.

Classify receptor blockers

Drugs that bind to receptors and decrease or block the physiological activity of a neurotransmitter are called antagonists.
