Node of Ranvier is a gap between two internodes of an axon. They are periodic gaps within an insulated axon. In other words, nodes of Ranvier can be defined as naked areas of an axon located between internodes. Therefore, an axon is exposed to the extracellular environments at the nodes ...

The neurons are long cells that have a cell body, that has a nucleus and most cytoplasm, dendrites that are short extensions and axons that are long extensions with myelin sheath secreted by Schwan cells. Myelin sheath is not continuous but interrupted in between to have a node of Ranvier....
The key difference between dermatomes and peripheral nerves is that dermatomes are areas of skin that send signals to the brain by using the spinal nerves,
The specific molecular events that underlie the age-related loss of cognitive function are poorly understood. Although not experimentally substantiated, ag
is useful on those occasions when unwanted insect visitors settle on the skin. Merkel cells are also in themechanoreceptorsgroup; these receptors adapt much slower than Pacinian corpuscles. When holding a coin in the palm of the hand, the Merkel cells will signal that it is still there after...
6. Node of Ranvier: - The myelin sheath is not continuous; there are gaps known as nodes of Ranvier. - These nodes allow for the rapid conduction of impulses by enabling ions to flow in and out of the neuron. Summary of Parts of a Neuron:- Soma (Cell Body/Cyton)- Dendron- Dendrit...
