The Nodes of Ranvier

Multiple Choice

The nodes of Ranvier:

A) Are distributed approximately every 1 to 2 millimeters (mm) along the membrane of the cell axon.
B) Contain a high density of modality-gated K⁺ channels for rapid depolarization of the membrane.
C) Contain a high density of voltage-gated Na⁺ channels for rapid repolarization of the membrane.
D) Have low membrane capacitance,preventing the accumulation of electrical charge.
E) Are heavily myelinated,which allows for rapid diffusion of an electrical potential.
