Graded potential occurs when triggered by a stimulus and gated ion channels open these gated channels can either be chemically gated or mechanically gated. In order to have graded potential threshold must be met in order to generate action potential. Good day!

What is a sub-threshold change in membrane potential within the cell body that decays as it travels away from its point of origin?
synaptic/graded potential
Is it true that a post synaptic potential is a graded potential that is the result of a neurotransmitter released into the synapse between two neurons?
because i dnt know hahaha
What are epsp?
EPSP is an abbreviation for excitatory postsynaptic potential. This is a graded depolarization of a postynaptic membrane responding to neurotransmitter stimulation.
Which membrane potential occurs because of the influx of Na plus through chemically gated channels in the receptive region of a neuron?
An excitatory postsynaptic potential, a type of graded potential, occurs because of the influx of Na+ through chemically gated channels in the receptive region, or postsynaptic membrane, of a neuron. Graded potentials are generated by chemically gated channels, whereas action potentials are produced by voltage-gated channels.
How long does an action potential occur for?
2 milliseconds.
What can occur when the effects of one graded potential are added onto the effects produced by another graded potential which can lead to an action potential.?
More sodium ions pile up (accumulate) at the axon hillock from the combination of the two (or more) graded potentials, which may be then be sufficient to initiate the action potential.

Dendrites conduct both graded and action potential?
no, dendrites and cell bodies can only have graded potential. action potential only occurs in axons
Is a postsynaptic potential a graded potential that is the result if a neurotransmitter released into the synapse between two neurons?
Yes it is true that graded potential can be called postsynaptic potentials. When a sensory neuron is excited by some form of energy, the resulting graded potential is called generator potential.
How does an action potential differ from a graded potential?
Action potentials also known as spikes, differ from graded potentials in that they do not diminish in strength as they travel through the neuron.
When a sensory neuron is excited by some energy the resulting graded potential is called?
Receptor potential or generator potential.
When a sensory neuron is excited by some of energy the resulting graded potential is called?
Receptor potential or generator potential.
What parts of a neuron is capable of generating a graded potential?
The dendrites portion of a neuron will generate a potential.
Graded potential are they all or none?
graded potential are by definition VARIABLE in strength, and therefore NOT all or none. They start out at their strongest strength, and degrade (become weaker) as they progress further along.
A postsynaptic potential is a graded potential that is the result of a neurotransmitter released into the synapse between two neurons?
true
Can graded potential form on receptor endings?
Yes, Graded potentials (otherwise known as postsynaptic potentials) can form on receptor endings.
When a sensory neuron is excited by some form of energy the resulting graded potential is called?
receptor or generator potential
