7
Q
what are neurons
A
- long thin cells that convey messages from 1 place to another
8
Q
how many neurons does the brain contain
A
billions
9
Q
what are synapses
A
Neurons pass messages from one neuron to the next via small gaps between the neurones – synapses
10
Q
what are neurotransmitters
A
- they are chemical messengers that act between neurones within the brain
11
Q
draw a neurone
A
12
Q
draw a neurotransmitter
A
13
Q
what is the difference between neurones and neurotransmitters
A
- neuron is a cell in the body
- neurotransmitter is a chemical compound that a neuron releases which allows neurones to send messages and communicate with other neurones
14
Q
what is the process of synaptic transmission
A
- electrical impulse –> dendrites in cell body
- electrical impulse –> Nucleus –> axon
- moves down axon (protected by myelin)
- electrical impulse arrives at axon terminal
- EI triggers release of neurotransmitters from presynaptic vesicles
- Neurotransmitter moves from presynaptic ending and is released into synaptic cleft
- Neurotransmitter binds with the postsynaptic endings receptor sites in the dendrites of the next neurone
- messengers on postsynaptic ending pass the electrical impulse on the dendrite
- The EI moves from dendrite to the cell body
