The cells of excitable and nonexcitable tissues share which one of these properties
A)a threshold potential
B)a resting membrane potential
C)an ability to open the Na⁺ gates
D)an ability to open the K⁺ gates

Question

Quizplus · Accepted Answer

Both excitable and nonexcitable tissues have a resting membrane potential, which is the membrane potential of a cell at rest. This potential is maintained by the concentration gradients of ions across the cell membrane and by the selective permeability of the membrane to different ions. Excitable tissues have the additional property of a threshold potential, which triggers an action potential, but nonexcitable tissues do not have this property. Both excitable and nonexcitable tissues can open the Na⁺ and K⁺ channels, but this does not distinguish them from each other.
