Synaptic transmission Flashcards
Where is the nucleus in the neuron
The soma
What travels down the axon
Action potential
What 2 things speed up transmission
Myelin sheath
Nodes of ranvier
What do the terminal buttons connect to
The effector (glands or muscles)
Or
The next neuron in the chain
Where are neurotransmitters in the neuron
The axon terminal (in the synaptic vescicle)
What are the 2 types of neurotransmitter
Excitatory: a neurotransmitter that increases the positive charge of the post synaptic neuron, making it more likely to fire
Inhibitory: a neurotransmitter that increases the negative charge of the post synaptic neuron, making it less likely to fire
Order of the reflex arc
Sensory > Relay > Motor
Name one excitatory neurotransmitter
Adrenaline
Name one Inhibitory neurotransmitter
Serotonin
What word fits this description: the sum charge of the neurotransmitters decides the chance of the neuron firing
Summation
What is meant by excitation
Excitation is a process by which neurotransmitters sum up as mostly positivel charges which increases the chance of firing the next neuron in the sequence
What is meant by Inhibition
Inhibition is a process by which neurotransmitters sum up as mostly negative charges which decrease the chance of firing the next neuron in the sequence
