What is the primary difference in graded potentials versus actions potentials?
  • a)
    Graded potentials occur in neurons of the peripheral nervous system, while actions potentials occur in neurons of the central nervous system
  • b)
    Graded potentials occur in axons, while action potentials occur in the dendrites and soma
  • c)
    Action potentials occur in axons, while graded potentials occur in the dendrites and soma
  • d)
    Graded potentials do not involve transient production of charged molecules inside the neuron, while action potentials involve the flow of charged molecules across the neuron membrane
Correct answer is option 'C'. Can you explain this answer?

What is the primary difference in graded potentials versus actions pot...
The primary difference between graded potentials and action potentials is their location within the neuron. Graded potentials occur in the dendrites and soma (cell body) of the neuron, where they are generated in response to incoming signals from other neurons or sensory stimuli. Graded potentials can be either depolarizing (excitatory) or hyperpolarizing (inhibitory) and their magnitude varies depending on the strength of the stimulus.
On the other hand, action potentials occur in the axons of the neuron. They are all-or-nothing events that are initiated when a graded potential reaches a certain threshold. Action potentials are characterized by a rapid and brief depolarization followed by repolarization of the neuron membrane. They are responsible for the long-distance transmission of signals along the axon, allowing information to be communicated between different regions of the nervous system.
