Neurons Carries impulses away
Carries impulses from from body of cell.
neighbouring neurons Terminal button allows
to the body of the next electric pulses to move
neuron across synapses
Protects and speeds up
the impulse
The Soma
Inside neuron = electrical impulse
Outside neuron = chemical impulse Increases speed, allows
impulses to ‘jump’ from
Contains DNA of cell each sheath
PNS: PNS - Peripheral nervous
CNS:
nerves branch from the brain system - which is in charge of
brain
communication network between the your senses and organs. It links
spinal cord
CNS and the body to the CNS and allows
motor neurons
Sensory neurons communication between the 2
relay neurons
Relay neurons with relay neurons.
Depolarisation:
When a neuron is in a resting state, the inside of the neuron is negatively charged compared to
the outside.
When a neuron is stimulated by a stimulus, the inside of the cell becomes positively charged.
This rapid shift in charge is called depolarisation.
It creates an electrical impulse that travels down the axon towards the terminal buttons.
The process is called an action potential being fired. It can only happen one at a time though.
