Medullated Nerve Fiber (Noun)
Meaning
A nerve fiber encased in a sheath of myelin.
Classification
Nouns denoting body parts.
Examples
- The medullated nerve fiber is responsible for transmitting signals at a faster rate than unmyelinated fibers.
- Medullated nerve fibers are found in the peripheral nervous system and are essential for rapid communication between different parts of the body.
- The myelin sheath surrounding the medullated nerve fiber acts as an insulator, allowing the signal to jump from node to node.
- Damage to the medullated nerve fiber can result in slower transmission of signals and potentially lead to neurological disorders.
- The medullated nerve fiber is composed of a central axon surrounded by a layer of myelin, which is formed by oligodendrocytes in the central nervous system.
