|
Which of the following is not true regarding saltatory conduction.
|
|
the nerve impulse jumps from node to node
|
|
|
it only occurs along myelinated neurons
|
|
|
it transmits action potential at a slower rate
|
|
|
it is important to maintaining homeostasis
|
Explanation:
Detailed explanation-1: -So, the correct option is ‘It transmits an action potential at a slower rate’.
Detailed explanation-2: -The ensheathment of neurons with the myelin enables rapid saltatory conduction of action potentials in the nervous system.
Detailed explanation-3: -Action potentials traveling down the axon “jump” from node to node. This is called saltatory conduction which means “to leap.” Saltatory conduction is a faster way to travel down an axon than traveling in an axon without myelin.
