resting membrane potentials

Flashcards covering the key concepts related to the electrical properties of the nervous system and membrane physiology.

Nervous System Communication

Uses electrical currents generated by ion gradients across membranes.

Neurons

Cells that exploit ion gradients to generate rapid electrical signals.

Voltage

The driving force causing separation of charged particles.

Current

The flow or movement of charged particles.

Resistance

The opposition to the flow of charged particles.

Resting Membrane Potential (RMP)

The potential difference across the membrane due to separation of charges.

Extracellular Fluid (ECF)

Fluid outside the cells with high sodium concentration.

Intracellular Fluid (ICF)

Fluid inside the cells with high potassium concentration.

Ion Channels

Proteins that allow specific ions to pass through the membrane.

Sodium-Potassium Pump

A mechanism that actively transports sodium out and potassium into the cell.
