Components of a neuron and action potential Flashcards
1
Q
What are the main parts that compose a neuron?
A
Soma, Dendrites, Axon, Axon Terminals and Synapses
2
Q
Where is the nucleus of the neuron located in?
A
Soma
3
Q
A long extension of the neuron, which transmit action potentials (electric signal) to other neurons and body parts
A
Axon
4
Q
Tree-like structure, which receives chemical signals (neurotransmitters) for the soma to process
A
Dendrites
5
Q
The junction between dendrites where signals are transmitted?
A
Synapse
6
Q
What are the stages of action potential (in order and with voltz)?
A
resting state (-70mV), threshold (-55mV), depolarisation to +40mV, repolarisation to -90mV, Hyperpolarisation to -70mV.
