Neurotransmitters

Question 1

What is a synapse?

Answer 1

The site where communication between neurons occurs.
Synaptic neuron terminal buttons, synaptic gap, and postsynaptic neuron dendrites.

Question 2

What is a neurotransmitter? And what is reuptake?

Answer 2

A chemical substance produced by a neuron that carries messages between neurons or neurons to muscles/organs.
Re-uptake: neurotransmitters that do not bind to receptors of postsynaptic neurons are absorbed back into the pre- terminal buttons.

Question 3

Glutamate

Answer 3

Excitory neurotransmitter. Enhances information transmission by making postsynaptic neurons more likely to fire. Brain function, learning, memory

Question 4

Gamma-amino butyric acid

Answer 4

Inhibitory transmitter. Makes postsynaptic neurons less likely to fire. Fine tunes neurotransmission in brain
