You Have Observed That Graded Potentials Typically Occur in the Dendrites

Multiple Choice

You have observed that graded potentials typically occur in the dendrites and cell body. What is the underlying reason for this?

A) Graded potentials can only travel a short distance by local current flow.
B) Graded potentials are caused by ligand and mechanically-gated channels that are most frequently found in dendrites and cell bodies.
C) Graded potentials are caused only by Na⁺ and K⁺ flowing through channels.
D) Graded potentials are both depolarizing and hyperpolarizing, which means they can't occur in axons where only depolarizing signals occur.
