Neuronal Excitation

NEURO-PWHWBU

Neuronal excitation can be caused electrically or chemically, such as a response caused by specific neurotransmitters binding to receptors of a neuron.

Which of the following is FALSE about neuronal excitation?

A

Right at the excitation location, the potential is positive inside the membrane and negative outside the membrane.

B

During the neuronal excitation, the membrane becomes more permeable to sodium ions.

C

In a reflex, the excitation is passed along the axon bi-directionally.

D

The uneven distribution of potassium and sodium ions across the neuronal membrane is the basis for neuronal excitation.
