Neurotransmitters

Neurotransmitters are released from the

• Dendrites

• Post-synaptic neuron

• Presynaptic neuron

• Schwann Cells

What is the chemical used by a neuron to transmit an impulse across a synapse to another nerve cell?

• Neurotransmitters

• Synapse

• Threshold

• Impulse

In order for a neuron to have an action potential, the neuron must receive more

• excitatory neurotransmitters

• inhibitory neurotransmitters

• agnostic neurotransmitters

• antagonistic neurotransmitters

Excess neurotransmitters in the synapse that goes back into the presynaptic neuron.

• Resting potential

• Reuptake

• Retroactivity

• Repolarization

• Amino Acid

• Enzyme

• Hormone

• Neurotransmitter

A signal chemical/molecule that transmits nerve impulses across synapses. For example, GABA, Serotonin, or Acetylcholine.
