Be sure to include the locauons where they typically occur, their size, the ion channels involved in producing them, all the properties associated with them, and their function. Also include their relationship with each other. 2. C

Explanation / Answer

Neuron is capable of having the following membrane potentials:

  

Cationic graded potential Anionic graded potential Due to Na+, K+ & Ca++ channels Due to Cl- channel When these channels are activated (eg. Na+), the resting membrane potential becomes more positive to excite a neuron ; i.e. Depolarization phase. When Cl- channel is activated, the resting membrane potential becomes more negative i.e Hyperpolarization which inactivates a neuron.
