<prompt> RMP of the neuron is:-700 V- 7 V-170 mV-70 mV  <response>: Ans: D - ve 70 mV Ref: Ganong, 22nd ed, p. 55Resting membrane potential RMPIt is the potential difference between inside and outside of the membrane of a cell at a resting state. RMP is maintained by K ion. The value for RMP varies for different kinds of tissues.RMP of various tissues are given belowRMP of neuron is: -70 mVRMP of cardiac muscle: --90 mVRMP of skeletal muscle: -90 mVRMP of smooth muscle: -50 mVNote:RMP is maintained by K ionRMP is close to isoelectric potential of Cl-Changes in the external K concentration affect the RMPChanges in the external Na concentration affect the action potential and not the RMP
