What happens when the threshold level is reached in a neuron?
An action potential is generated
The neuron dies
The signals are ignored
The neuron becomes inactive
What is the process called when neurotransmitters are reabsorbed by the presynaptic neuron?
Binding
Degradation
Reuptake
Diffusion
What type of neurotransmitters make it more likely for the postsynaptic neuron to generate an action potential?
Degraded neurotransmitters
Reuptake neurotransmitters
Excitatory neurotransmitters
Inhibitory neurotransmitters
What initiates the release of neurotransmitters from the presynaptic neuron?
Myelin sheath
Dendrite activation
Action potential
Synaptic cleft
What is the small gap between the presynaptic neuron and the postsynaptic neuron called?
Dendrite
Cell body
Synaptic cleft
Axon terminal
Which cells form the myelin sheath in the central nervous system?

Glial cells
What is the primary function of neurotransmitters?
To bind to receptors on the postsynaptic neuron
To transmit electrical impulses
To generate action potentials
To insulate the axon
What happens to neurotransmitters after they have conveyed their signal?
They remain in the synaptic cleft indefinitely
They are permanently attached to receptors
They are broken down or reabsorbed
They are converted into electrical impulses
