neurons + neurotransmitters Flashcards
(11 cards)
neurons
cells that transmit messages back and forth from CNS to parts of the body
- help the body to receive, interpret, and respond to information
synaptic transmission
- action potential reaches axon terminal
- vesicles containing neurotransmitters are released
- neurotransmitters diffuse across synapse to bind to receptors on postsynaptic membrane
- action potential travels to postsynaptic neuron
acetylcholine
thought, learning, memory, muscle action, attention, awakening
norepinephrine
attention, responding, contracts blood vessels (increasing blood flow)
serotonin
wellbeing, happiness, sleep cycle, digestive system regulation
dopamine
inhabitation of unwanted movement, behaviour, motivation, pleasure
epinephrine
increases heartrate, blood pressure, blood glucose levels, respiratory rate
gamma-amino-butyric acid (GABA)
inhibitory, calming, sedative
glutamate
excitatory, found in amino acid
neuroplasticity
the brain’s ability to change its structure and function in response to experience or damage
neurogenesis
the forming of new neurons
