A change in smooth muscle cell tension in the absence of a change in electrical potential of the cells is described as a(n)
A) pacemaker potential.
B) slow wave potential.
C) pharmacomechanical coupling.
D) electromechanical coupling.

Question

Quizplus · Accepted Answer

Pharmacomechanical coupling refers to the process where smooth muscle cells change their tension or contract without a change in their electrical potential, often in response to chemical signals or drugs, unlike electromechanical coupling which involves changes in electrical potential leading to muscle contraction.
