Neural Communication and Neurotransmitters Flashcards
(10 cards)
Neurons interact so closely that, even with a microscope, it is difficult to determine where one neuron ends and another begins.
Fun Fact!!
-The junction between the axon tip of the sending neuron and the dendrite of the receiving neuron.
-Synaptic gap (Less than one-millionth of an inch wide).
Synapse
-Chemical messages that cross the synaptic gaps between neurons.
-Bind to receptor sites on receiving neurons.
-Influences whether receiving neuron will generate a neural impulse.
Neurotransmitters
-“Morphine within”
-Natural opiate-like neurotransmitter linked to pain control and pleasure.
Endorphins
Enables muscle action, learning, and memory
Acetycholine (ACh)
Influences movement, learning, attention, and emotion.
Dopamine
Affects mood, hunger, sleep, and arousal.
Seretonin
Helps control alertness and arousal
Norepinephrine
A major inhibitory neurotransmitter.
GABA
A major excitor neurotransmitter; involved in memory
Glutamate
