2.2.2 part 2

• Synapse: microscopic gaps that separate the terminal buttons of the one neuron from receptors
• Axon Terminal: small swellings that are found at terminal ends of axons.
• Action Potential: rapid sequence of changes in the voltage across a membrane
• Neurotransmitter: endogenous chemicals that allow neurons to communicates
• vesicle: small fluid-filled bladder
• myelin sheath: insulating layer that covers/forms around nerves
• receptors: binds specific substance to make a special effect to the cell
• presynaptic neuron: transmits towards synapses
• postsynaptic neuron: integrates signals and decides what goes next
