Membrane potential   -distribution of charge across the cell membrane, based on the charges of ions

Excitable membrane

cell membrane that regulates the movement of ions so that an electrical signal can be generated

Electrochemical exclusion

principle of selectively allowing ions through a channel on the basis of their charge

Size exclusion

principle of selectively allowing ions through a channel on the basis of their relative size

cell membrane that regulates the movement of ions so that an electrical signal can be generated  (electrochemical Exculsion ) 

Definition

channel that is not specific to one ion over another, such as a nonspecific cation channel that

allows any positively charged ion across the membrane. Allow cations—particularly Na+,

K+, and Ca2+—to cross the membrane, but exclude anions
