Information Exchange Flashcards
Process of information exchange
The axon terminal’s and the presynaptic neuron are stimulated. The terminals contain synaptic vesicles, which empty neurotransmitters into the synapse between the neurons. Neurotransmitters activate the postsynaptic neuron, changing it’s voltage. Once the excitation of threshold is reached, the action potential begins, and a neuron fires.
Nerve impulses
Neurons communicate by receiving and transmitting these impulses.
Synapse
The small gap between neurons where information is exchanged.
Synaptic vesicles
Places where neurotransmitters are stored until release into the synapse.
Neurotransmitters
Chemicals that stimulate your own so they can communicate.
Excitatory neurotransmitter
Make neurons more likely to fire.
Inhibitory neurotransmitter
Make neurons less likely to fire.
Excitation threshold
The voltage difference necessary to destabilize a neuron, causing an action potential to occur.
Action potential
The brief change and electrical charge the destabilize is a neuron. The action potential stimulates the axon terminal, restarting the process.
