Question 1
Conduction occurs along an axon because
◦ entry of Na
+ stimulates the adjacent channels to open.
◦ axonal transport "walks" voltage changes along the membrane.
◦ once Na
+ enters the cell, the entire membrane depolarizes simultaneously.
◦ exit of K
+ stimulates the adjacent channels to open.
Question 2
Conduction speed can be increased by
◦ removing myelin.
◦ increasing the length of a neuron.
◦ increasing the diameter of a neuron.
◦ All of the above.
