answer correct pls select any one option
Answers
Answer:
The Node of Ranvier is the 1-2 micrometre gap between the glial cells of the myelin sheath. These glial cells are called Schwann cells, and they help to electrically insulate the neuron. The Nodes of Ranvier are only present when the axon of a neuron is myelinated.
Answer:
nervous cell
Explanation:
A nerve cell or neuron is the structural and functional unit of the nervous system. The cell body of a neuron is known as soma. It has two types of processes, called axons and dendrites. Dendrites are the short cytoplasmic extensions of cyton which receives a nerve impulse.
The long cytoplasmic process of a cell body, which transmits an impulse from a cell body to other neurons is termed as an axon. The axon is covered by a lipid-rich membrane, called myelin sheath. The myelin sheath is formed by Schwann cells and each Schwann cell covers a part of the axon. The region, where axon is not covered by myelin sheath is the junction of the adjacent myelinated segments, called node of Ranvier.
