What is non-myelinated nerve fiber?
a nerve fiber that lacks the fatty myelin insulating sheath. Such fibers form the gray matter of the nervous system, as distinguished from the white matter of myelinated fibers. Also called nonmedullated nerve fiber.
What type of fibers make up the posterior and anterior roots of the spinal nerve?
Both Afferent and Efferentboth sensory and motorContains motor & sensory fibers!The spinal cord consists of nerve fibers that are afferent and efferent.
What is the covering over nerves fibers made up of living cells?
The covering over nerve fibers made up of living cells is known as the myelin sheath. This sheath is primarily composed of oligodendrocytes in the central nervous system and Schwann cells in the peripheral nervous system. Myelin serves to insulate the nerve fibers, allowing for faster transmission of electrical signals along the axon. Additionally, it plays a role in protecting and supporting the nerve fibers.
What are medullated and non- medullated nerve fibres?
Depending on the number of sheaths ,nerve fibres are of two types :-Myelinated (Medullated) Nerve Fibre.Nonmyelinated (NonMedullated) Nerve Fibre.Myelinated (Medullated) Nerve Fibre.:-are those nerve fibres which are covered by two sheaths ,myelin & neurolemma.Nonmyelinated (NonMedullated) Nerve Fibre.:-these nerve fibres are devoid of myelin sheath .However,neurolemma is present.
What is histology of gut?
Histology of the gut involves studying the microscopic structure of the different layers of the gastrointestinal tract, including the mucosa, submucosa, muscularis externa, and serosa. This allows for the identification of specialized cells, tissues, and structures that make up the gut, such as epithelial cells, goblet cells, smooth muscle fibers, and nerve fibers. Histological analysis of the gut can provide insights into the function and health of the digestive system.

Which endocrine glands are made up primarily of nerve fibers?
The thyroid gland is primarily made up of nerve fibers. These endocrine glands are mostly made up of connective tissue.
What are the differences between myelinated and unmyelinated nerve fibers in terms of their conduction speed and efficiency?
Myelinated nerve fibers conduct electrical signals faster and more efficiently compared to unmyelinated nerve fibers. This is because the myelin sheath insulates and speeds up the transmission of signals along the nerve fibers.
Fibers are what?
cloth is made up of thin long structures called fibers
What is the covering of nerve fibers made up of living cells?
what is the portion of the brain containing control certer for body's functions and emotions: means "under the inner rool"
Another name for a bundle of nerve fibers is what?
It is called a dendrite.~
What does the optic nerve look like?
It is made up of about 1 million small individual thread-like nerve fibers that come from the retina.

What are the colors of your nervous system?
Nervous tissue does not have a specific color as it is made up of cells, fibers, and blood vessels. However, nerve tissue can appear white due to the myelin sheath that surrounds certain nerve fibers.
