Observe the figure below show two ion channels.1. This pump does not work on part of the axon. Why? 2. Which are the ions participated in the process? 3. Suggest the use of this process in nerve impulse conduction? |
|
Answer» 1. Myelin sheath: Myelin sheath act as insulator for axon and it increases the speed of nerve impulse conduction by saltatory conduction. 2. Na+ and K+ 3. It creates action potential when stimulated by allowing the inward movement of Na ions through the Na+ channel and outward movement of K+ through K+ channel. |
