Neurons Flashcards
what are the two principle cells of the nervous system
GLIA
neurons
what are the main components of a neuron
Dendrites
Axons
Myelin sheath
Terminal buttons
what are the two types of neurons
inhibitory
excitatory
what is the pre-synaptic terminal
end of an axon
what is present a pre-synaptic terminal
neurotransmitters
where are neurotransmitters released to
the synaptic cleft
what does the post synaptic neuron contain
receptor molecules for neurotransmitters
by what method are neurotransmitters transported
simple diffusion
what is unique about receptor molecules
specific shapes for neurotransmitters to bind and fire new action potential
what does EPSP stand for
Excitatory post synaptic potential
what do EPSPs do
make the target neuron more likely to fire an action potential
what does local action refer to
neurotransmitters are active in specific synapses
what is the role of action of a hormone
Needs to be released into the bloodstream and bind to specific receptors at organs in the body
do not bind with synapse
