Does myelin sheaths slow down nerve impluses?
No, a myelin sheath speeds up the rate of nerve transmission.
Which neuroglial cell is responsible for the production of myelin sheaths around axons in the central nervous system?
Oligodendrocyte; processes of the oligodendrocytes form the myelin sheaths around the CNS nerve fibers
An autoimmune disease which results in the destruction of myelin sheaths is called?
Multiple Sclerosis
Which of the following PNS neuroglia help to form myelin sheaths around larger nerve fibers in the PNS?
Schwann Cell
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.
Where are myelin sheaths located?
Myelin sheaths are located around the nerve cells. In central as well as peripheral nervous system.
What insulates nerve fibers?
Myelin sheaths insulate nerve fibers
What is the gap called that separates the myelin sheaths?
The gap between myelin sheaths is called the node of Ranvier. These nodes are important for enhancing the speed of nerve impulse transmission along the axon by allowing action potentials to "jump" between them in a process known as saltatory conduction.
Is it becaue they are large with thick myelin sheaths?
Your question is not complete. There is not enough information. What are you referring to as "they". Some nerve fibers have thick myelin sheaths and some don't.
The speed of impulse conduction along an axon may be increased by?
By myelin sheath.
Does myelin sheaths slow down nerve impluses?
No, a myelin sheath speeds up the rate of nerve transmission.
What features of nerves improve impulse conduction velocity?
myelin sheaths
Does oligodendrocytes serve the same purpose in the central nervous and periphial nervous system?
No, they form myelin sheaths on axons in the CNS while schwann cells form myelin sheaths in the PNS. Hope this answers your question.
In a typical neuron sheaths of fatty tissue are called?
In a typical neuron, sheaths of fatty tissue are called the Myelin sheath. The myelin sheath surrounds parts of the axon of a nerve cell which speeds up neurotransmitters.
Which neuroglial cell is responsible for the production of myelin sheaths around axons in the central nervous system?
Oligodendrocyte; processes of the oligodendrocytes form the myelin sheaths around the CNS nerve fibers
An autoimmune disease which results in the destruction of myelin sheaths is called?
Multiple Sclerosis
Does a nervous breakdown affect the myelin sheaths?
No. It does not. It can not. It neither affect the neurons also.
