Graded Potentials Flashcards
1
Q
What is a graded potential?
A
Small deviations from resting potential (-70mV)
2
Q
What happens during hyper polarisation?
A
Membrane becomes more negative
3
Q
What happens during depolarisation?
A
Membrane becomes more positive
4
Q
What does the variation in amplitude of the the signals depend on?
A
-Strength of stimuli
-If localised
5
Q
Where do graded potentials mostly occur?
A
Dendrites and the cell body of a neuron
