In a neuron, a graded potential:
A) does not vary in magnitude.
B) becomes stronger as it propagates.
C) only generates slow action potentials.
D) fades out within a few millimeters.
E) propagates only along unmyelinated axons.

Question

Quizplus · Accepted Answer

Graded potentials vary in magnitude, weaken as they travel through the neuron, and can occur in both myelinated and unmyelinated axons. They do not inherently generate slow action potentials. The key characteristic of a graded potential is that it fades out within a few millimeters of its origin due to the leakage of ions through the membrane and the resistance of the cytoplasm.
