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.
The speed of nerve impulse transmission through the axon of a sensory neuron will be quickest in?
I'm guessing; "myelinated nerve fibres" contrary to the much slower "non-myelinated nerve fibres"
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 are non petrochemical synthetic fibers?
Non-petrochemical synthetic fibers are fibers that are not derived from petroleum-based sources. They are typically made from natural materials such as cellulose (e.g., bamboo, lyocell) or protein (e.g., soy, corn) rather than synthetic chemicals derived from petroleum products. Examples include modal, viscose, and PLA fibers.
What are two end uses of regenerated fibers?
Two end uses of regenerated fibers are clothing production, where they are used to create garments like t-shirts, dresses, and activewear, and non-woven applications, such as wipes, filters, and medical products.
What spinal segment structure carries non-myelinated GVE fibers?
The white ramus communicans carries non-myelinated GVE fibers.

Does a worm have a myelinated or non-myelinated neuron?
non-myelinated

How is nerve impulse conducted along a myelinated nerve fiber?
In non-myelinated axons, the nerve impulse is going to be produced when the action potential accross a membrane makes a wave of depolarization followed by a wave of repolarization. With the absence of the myelin, the impulse is transmitted continuously throughout the membrane. In a non-myelinated nerve, once an end of the cell, the dendrite, is depolarized, the depolarization a.k.a., the action potential, moves along the nerve membrane, and the area of membrane immediately behind the depolarized section becomes repolarized.
What animals have non-myelinated neurons?
Hagfish, Lobsters and Crabs. As well as Mantis Shrimp.
What are the two types of nerve?
sensory- receives information from environment motor- sends signals to muscles to allow you to move 1 other type of nerve is... autonomic - involuntary your welcome, j.m
How does myelination affect nerve conduction velocity?
Myelination will speed the nerve conduction velocity considerably. Myelin is found in Schwann cells which encircle a given axon. It acts mainly as an insulator so that depolarization in one cell does not set off depolarizations in adjoining cells. When a neural membrane is depolarized, local currents are set up between positive and negative ions causing membrane conduction. In myelinated fibers, the local currents go from one internode (or node of Ranvier) in between two Schwann cells to the next internode. Thus we have "salutatory conduction" where a neural impulse actually jumps from one internode to the next without being conducted down the entire cell membrane.
What are staple fibers?
Staple fibers are short, non-continuous fibers. All natural fibers, except silk, come in staple form.
What are medullated and non- medullated nerve fibres?
