Neurotransmition/ neurons/nervous system Flashcards
norepinephrine
FFF
Dopamine
Reward system
motivation
motor control over voluntary movement
serotonin
regulates sleep,mood,digestion,dreaming
Acetycholine
motor control over muscle
sleep
attention
learning
GABA
Blocks signals from CNS
Glutamate
memory cognition and mood regulation
endorphine
pain reduction
Axon
Where impulse travels
Mylin sheath
Act as insulation over axon
Dendrite
Where stimulous is received
Terminal button
Where neurotransmitters are released to react in the synapse
cell body
Stores organelles
synapse
The gap where communication happens
affarent
Input sensory neuron
efferent
Output motor neuron
action potential
Rapid sequence of change in voltage across membrane
resting state
When a neuron is inactive electrical charge inside is slightly more negative than the outside
The difference in charge in a inactive neuron
inhibitory
Decrease firing of action potential
excitatory
Increase action potential
Agonist
Enhance effects and or strengthen
antagonist
Decrease of block effects
Parasymphathetic
Relaxation and calming of the brain and body
symphatetic
Prepares body for stress response FFF
central
Brain and spinal cord
somatic
Voluntary movements
Autonomic
Involuntary movements
