Communication within a neuron
This is the type of signal sent along an axon
What is Action Potential?
These are glia cells that wrap themselves around a neuron to protect it.
What is a myelin sheath?
This neurotransmitter controls sleep-wake cycles.
What is melanin?
These are chemical messengers that cross the synaptic gap.
What are neurotransmitters?
This is the period immediately after an action potential when a neuron cannot fire again.
What is the refractory period?
These are two parts of a neuron specifically designed for the sending and receiving of electrical impulses.
What are the axon and dendrite?
What neurotransmitter is typically associated with addiciton?
What is dopamine?
This process describes how neurotransmitters cross the synaptic gap.
What is synaptic transmission?
During this phase of an action potential, the neuron’s charge returns to its resting state
What is repolization?
"This long structure transmits electrical impulses away from the cell body to other neurons
What is the Axon?
The most common excitatory neurotransmitter.
What is Glutamate?
These block neurotransmitters from binding to receptor sites
what are antagonists
This is the term for the process that generates an electrical signal in a neuron when it reaches threshold
What is depolarization?
The junction between the axon tip of a sending neuron and dendrite of the cell body of the receiving neuron.
What is the synaptic gap?
A deterioration of this neurotransmitter causes Alzheimer's.
What is Acetylcholine?
These block a neurotransmitter's action.
What are antagonists?
This is the ion that flows into the neuron during depolarization to create the action potential
What is a sodium ion?
This part of the neuron contains the nucleus and performs most of the cell's functions
What is the cell body?
This type of neurotransmitter can increase the likelihood of a neuron firing an action potential
What is an excitatory neurotransmitter?
This type of neurotransmitter decreases the likelihood of the postsynaptic neuron firing.
What is an inhibitory neurotransmitter?
