(7 cards)
1
Q
What is a neuron?
A
Specialised nerve cells which are part of the nervous system
2
Q
How do they transmit information?
A
Electrically (through action potentials) and chemically (through neurotransmitters)
3
Q
What do all neurons consist of?
A
Cell body, dendrites and axons
3mm - 1m long
4
Q
What are dendrites and what do they do?
A
Branch like structures protruding from cell body
They receive signals from other neurons
Connected to cell body
5
Q

A
They control the centre of neuron
They contain all genetic information of the cell
Connected to axon
6

A
Long protruding structure
Action potential carried along axon where it terminates at terminal button
