Resting Membrane Potential - Coggle Diagram
Resting Membrane Potential
Properties of RMP
Membrane permeability
Flow of Sodium
Flow of potassium
K+ higher in cell thus efflux occurs, causing intracellular to become negative
Cell membranes have lot of K+ leaking channels that makes it more permeable to K+
Sodium-Potassium Pump
3 sodium pump out while 2 potassium pump in
Lose 1 negative ion
Negative charge inside the membrane
Ionic distribution across membrane
Extracellular ions
Sodium
Chloride
Intracellular ions
Potassium
Protein
Factor Contribute to RMP
Sodium-Potassium ATPase pump
3 sodium go out, 2 potassium go in
Negatively charged protein ions remain in membrane
Leakage of potassium and sodium through nerve membrane
K+ is main contributing factor to negative RMP in nerve and skeletal muscle
Action Potential
Can bring sensory info by generation of AP
Sudden change from normal RMP to positive potential and change back to negative RMP
Resting stage, depolarization, repolarization, hyperpolarization
Excitable cells
Cardiac
Smooth
Skeletal
Nerve
