What is the layer of myelin that surrounds an axon called? Group of answer choices

1. Node of Ranvier
2. Perichondrium
3. Perimysium
4. Myelin sheath
5. Periosteum

The gaps (approximately 1 micrometer wide) formed between myelin sheath cells long the axons are called Nodes of Ranvier. Since fat serves as a good insulator, the myelin sheaths speed the rate of transmission of an electrical impulse along the axon.

I think the answer is Nodes of Ranvier but I’m not sure. I hope this helped <3

What do you mean about innate behavior i don’t get it

Ican not answer this question since it does not have enough information
