Neuron & Neurotransmission

Definition: These increase the likelihood of a neuron firing (such as acetylcholine).

• Antagonists

• Inhibitory neurotransmitters

• Axons

• excitatory neurotransmitters

A neurotransmitter that enables learning and memory and also triggers muscle contraction (plays a role in consolidation of memory in hippocampus).

• Gaba

• Serotonin

• Acetylcholine

• Norepinephrine

Definition: A nerve cell; the basic building block of the nervous system.

• Axon

• Neuron

• Dendrite

• Ganglion

Definition: These decrease the likelihood of a neuron firing (such as serotonin).

• Excitatory neurotransmitters

• Inhibitory neurotransmitters

• Agonists

• Dendrites

Definition: Gap between neurons where info is transmitted from one neuron to the next.

• Axon

• Synapse

• Dendrites

• Myelin Sheath

Definition: chemical messengers that cross the synaptic gaps between neurons.

• Neurotransmitters

• Acetylcholine

• Hormones

• Enzymes

Definition: a neural impulse; a brief electrical charge that travels down an axon.

• resting potential

• action potential

• synapse

• reuptake

Definition: A molecule that, by binding to a receptor site, stimulates a response.

• Antagonist

• Agonist

• Blocker

• Axon

Definition: Locations on dendrites of a neuron into which a specific neurotransmitter fits like a key into a lock.

• axons

• receptor sites

• axon terminals

• synapses

Definition: a compound that blocks or inhibits the action of a neurotransmitter

• Agonist

• Action Potential

• Antagonist
