CMB1004 Excitable Cells Questions and
Correct Answers | Latest Update
What are the four regions of a neurone?


 Dendrites

 Cell Body

 Axon

 Axon Terminal




Define an excitable cell


 Any cell capable of generating an action potential




Describe how the resting potential is maintained


 Cell contains slight -ve charge (70mv)

Maintained via high permeability of membrane to K+ and active transport of Na+ across

membrane




Define an action potential


 A rapid change in membrane potential




What is the equilibrium potential?

, Best Grades | Must Pass | Latest Update | Correct Answers | 2024/ 2025

 The point at which the electrical gradient of th e cell is equal and opposite

to the concentration gradient




What is the Nernst equation?







What occurs at each stage of an action potentials generation?


 Depolarisation: Membrane potential increases from RMP

Repolarisation: Membrane potential decreases following depolarisation


Hyperpolarisation: Membrane potential falls below RMP




Describe the activity of voltage gated ion channels during action potential generation


 1) Resting state, no gates open

2) Slow rising phase, some Na+ gates open, small amounts of Na+ enters cell


3) Rapid rising phase, all Na+ gates open, some K+ gates open


4) Early repolarisation, all K+ channels open, some Na+ closed


5) Hyperpolarisation, all Na+ closed, some K+ open




Define absolute refractory period
