What type of ion channels are present on the neural membrane?
Options
- ASodium channels
- BPotassium channels
- CSelectively permeable channels
- DSodium-potassium channels
Correct answer
C. Selectively permeable channels
Step-by-step solution
The electrical potential difference across the resting plasma membrane is called the resting potential.The outer surface of the axonal membrane possesses a positive charge while its inner surface becomes negatively charged and therefore is polarised Different types of ion channels are present on the neural membrane, which are selectively permeable to different ions . The sodium-potassium pump transports 3 Na⁺ ions outwards for 2 K⁺ ions into the cell. When a neuron is resting, the axonal membrane is comparatively m
