PPT-GRADED POTENTIAL & ACTION POTENTIAL

بسم الله الرحمن الرحيم Objectives Define graded potential and action potential Describe characteristics of graded potential C ompare between the different phases of excitability during a nerve action . Introduction A All cells possess a membrane poten tial related to the nonuniform distribution of and differential permeability of Na K and A B Nerve and muscle are excitable tissue that use this potential by undergoing controlled transient rapid c Learning Objectives.
