A chemoelectrical signal that can travel along cell membranes in a wave-like pattern is a(n)?
OverLord2011 [107]

A chemo electrical signal that can travel along cell membranes in a wave-like pattern is called a nerve impulse.

What is a nerve impulse?

  • A nerve impulse is an action potential generated across the plasma membrane of the neurons of our nervous system.
  • The electrical potential difference generated across the neurilemma i,e., the plasma membrane of the neurons (due to the reception of the external stimulus), is responsible for the generation of the nerve impulse.
  • Neurotransmitters, chemicals like acetylcholine, dopamine, etc., are also involved in transmitting nerve impulses across neurons.

Hence, the chemoelectrical signal that can travel along cell membranes in a wave-like pattern is a nerve impulse.
