Node of Ranvier – History Structure .
Nodes of Ranvier are tiny gaps in the myelin sheath that cover nerve cells. The myelin sheath helps to speed up the transmission of nerve impulses. The gaps between the Schwann cells are called nodes of Ranvier. They are important because they are the only part of the nerve cell that has contact with the axon, which is the part of the nerve cell that carries the nerve impulse. 
Overview
Many vertebrate axons are surrounded by a myelin sheath, allowing rapid and efficient saltatory (“jumping”) propagation of action potentials. The contacts between neurons and glial cells display a very high level of spatial and temporal organization in myelinated fibers.
This organization demands a tight developmental control and the formation of a variety of specialized zones of contact between different areas of the myelinating cell membrane. Each node of Ranvier is flanked by paranodal regions where helicoidally wrapped glial loops are attached to the axonal membrane by a septate-like junction.
Structure:
The nodes of Ranvier are important for the conduction of nerve impulses. They are small, elongated swellings that occur at intervals along the length of a nerve fiber. The nodes of Ranvier are responsible for the rapid transmission of nerve impulses.
The Schwann cells wrap around the nerve fiber and form a layer known as the myelin sheath. The oligodendrocytes are located between the Schwann cells and the nerve fiber. They form a layer known as the internode. Node of Ranvier – History Structure .
The myelin sheath is important for the conduction of nerve impulses. It is a layer of cells that wrap around the nerve fiber. The myelin sheath is formed by the Schwann cells. The Schwann cells are responsible for the production of the myelin sheath.
The oligodendrocytes are important for the conduction of nerve impulses. They are cells that are located between the Schwann cells and the nerve fiber. The oligodendrocytes are responsible for the production of the myelin sheath.
Node of Ranvier Function in Neuron:
This exposed segment of axon is important for the conduction of nerve impulses. The node of Ranvier is rich in voltage-gated sodium channels, which are responsible for the rapid transmission of nerve impulses.
A neuron is a nerve cell in the brain and spinal cord. It is a type of cell that sends and receives messages. The neuron has a cell body, dendrites, and an axon. The cell body is the largest part of the neuron. The dendrites are the long, thin branches that come out of the cell body. The axon is the long, thin part of the neuron that sends messages to other neurons. The axon is covered in a myelin sheath. The myelin sheath is a layer of fat and protein that protects the axon. Schwann cells are cells that help to protect and support the axon.
There are three parts to a neuron: the cell body, the dendrites, and the axon. The cell body is the largest part of the neuron. The dendrites are the long, thin branches that come out of the cell body. The myelin sheath is a layer of fat and protein that protects the dendrite. The axon is the long, thin part of the neuron that sends messages to other neurons. The myelin sheath is a layer of fat and protein that protects the axon. Schwann cells are cells that help to protect and support the axon.
Node of Ranvier Function in Neuron:
The cell body is the largest part of the neuron. The cell body contains the nucleus of the neuron. The nucleus is the part of the cell that contains the DNA. The cell body also contains the cytoplasm of the neuron. The cytoplasm is the part of the cell that contains the proteins and other chemicals that the neuron needs to function.
The dendrites are the long, thin branches that come out of the cell body. The myelin sheath is a layer of fat and protein that protects the dendrite. The myelin sheath helps the neuron to send messages faster.
The axon is the long, thin part of the neuron that sends messages to other neurons. The myelin sheath is a layer of fat and protein that protects the axon. The my
