Question

Identify the FALSE statement.

A) Under normal conditions, all action potentials in a given cell are identical.
B) Between nodes of Ranvier, signal conduction is decremental.
C) The amplitude of the action potential depends on the amplitude of the graded potential that precedes it.
D) The voltage-gated sodium and potassium channels begin to open at the same time.
E) A, B, and D are true.

Answer 1

The FALSE statement is that between nodes of Ranvier, signal conduction is decremental.

Step-by-step explanation:

The FALSE statement among the given options is B) Between nodes of Ranvier, signal conduction is decremental.

Signal conduction between nodes of Ranvier is actually saltatory, meaning it jumps from one node to another. This type of conduction is faster than continuous conduction, which occurs in unmyelinated axons.

Therefore, option B is the correct answer.
