Question

At the nodes of Ranvier there is a jumping of action potential. It is known as
a. Recovery phase
b. Active phase
c. Saltatory conduction
d. Neurotransmitter

Answer 1

Nodes of Ranvier are also known as myelin-sheath gaps. It normally befalls along a medullated axon. It is where the axolemma is made to expose to the extracellular space. The nodes of Ranvier are said to be uninsulated and extremely supplemented in ion channels. This allows them in order to contribute to the exchange of ions which were required to revive the potential of the act.

Complete answer:

Option C:
The axons that are covered with the myelin sheath secreted by the Schwann cells are possessed by the myelinated neurons. On the other hand, the myelin sheath is not continuous. Also, there are some places called the nodes of Ranvier where the myelin sheath is absent. This type of nerve impulse conduction is called the saltatory conduction since the impulse looks as if they are jumping from one node to the next.

Option D:
We can say that the neurotransmitters are biochemical runners that communicate a message from a nerve cell that travels across the synapse to a target cell.

Option B:
The active phase is the most predictable period of the last hours during which the mother gives birth.

Option A:
The period throughout which a nerve or muscle is incompetent of retorting to encouragement, esp. directly succeeding a preceding stimulation is called a recovery phase.

Hence, the correct answer is option (C).

Note: We can say that a form of nerve impulse transmission in which the instinct jumps from one Ranvier's node to the next is called Saltatory conduction. It does so instead of wandering the entire length of the nerve fiber. Thus, we can say that this is an act of the propagation of action potentials laterally the myelinated axons from one node of Ranvier to the next one.
