What schwann cell forms around the myelin sheath?
axon of a neuron in the peripheral nervous system.Schwann cells form a myelin sheath around the Axon.
Special glia called Schwann cells form the myelin sheath which cover axons in the peripheral nervous system. The myelin sheath is actually two layers. The first layer surrounding the axon is called the myelin sheath and it is made up of the plasma membrane of the Schwann cells. The Schwann cells cytoplasm creates the second layer and is called the neurolemma. A neuron in the peripheral nervous system with a myelin sheath is called a… Read More
Because the sheath is produced by several Schwann cells that arrange themselves end to end along the nerve fiber, each Schwann cell forms only one part of the tiny segment of the sheath.
The glial cells: oligodendrocytes for central nervous system and schwann cells for peripheral nervous system.
Neurolemmocytes. No, right answer is Schwann cells.

These cells are called Schwann cells. They lay down the myelin so that the axon is not short circuited and the space between the cells (Nodes of Ranvier) allow for very rapid movement as the action potential "jumps" from one node to the next.
Myelin is a dielectric (electrically insulating) material that forms a layer, the myelin sheath, usually around only the axon of a neuron.
oligodendrocytes for C.N.S. and shcwann cells for P.N.S.
Muscles and glands are not myelinated. It is the axon of a neuron that is myelinated. The myelin forms a layer called myelin sheath that makes the nervous system function properly.
What is the fatty substances produced by certain glial cells that coat the axons of neurons to insulate protect and speed up the neural impulse?
Myelin, or myelin sheath is a fatty substance that forms around the axons of certain glial cells.
The myelin sheath forms a protective layer over nerves. However, it is not present on all nerves. Retinal nerves for instance normally are devoid of myelin.
Schwann cells are cells that are part of the nervous system, which warps around a nerve fiber and forms the nerve-insulating layer. Schwann cells are not affected greatly in multiple sclerosis, as MS is an autoimmune disease of the CENTRAL nervous system, and Schwann cells are only present in the PERIPHERAL nervous system. In the CNS, oligodendrocytes are responsible for insulating the axons with myelin, but are hardly affected in MS, as MS causes destruction… Read More
The cells that are thought to enable myelination to take place are called Glial Cells, which wrap themselves around the axions in a spiral fashion. This creates a sheath, or insulation, around the axion. It is often referred to as 'White Matter'.
A nerve fiber is a threadlike extension of a nerve cell and consists of an axon andmyelin sheath (if present) in the nervous system. There are nerve fibers in the central nervous system and peripheral nervous system. A nerve fiber may be myelinated and/or unmyelinated. In the central nervous system (CNS), myelin is produced byoligodendroglia cells. Schwann cells form myelin in the peripheral nervous system (PNS). Schwann cells can also make a thin covering for… Read More
Myelin Email this page to a friendShare on facebookShare on twitterBookmark & SharePrinter-friendly version Myelin is an insulating layer that forms around nerves, including those in the brain and spinal cord. It is made up of protein and fatty substances. The purpose of the myelin sheath is to allow impulses to transmit quickly and efficiently along the nerve cells. If myelin is damaged, the impulses slow down. This can cause diseases such as multiple sclerosis.
Myelin is the material that forms a layer around the axon of a neuron. It is essential for the neuron because it increases the speed of the impulses that propagate along the fiber.
Larger diameter axons conduct impulses more rapidly than axons with a smaller diameter. Larger axons tend to be myelinated and conduct impulses rapidly. Myelin is a substance rich in lipid that forms an electrical insulation layer around the axon. This insulating myelin sheath allows impulses to be transmitted more rapidly then small diameter axons that are nonmyelinated.
The perineurium is found in the peripheral nervous system. It is a membrane which forms a protective sheath around the fascicles (bundles of nerve fibres).
Which cell forms the myelin sheaths that surround the axons of some of the neurons in the central nervous system?
CMT is caused by mutations in genes that produce proteins involved in the structure and function of either the peripheral nerve axon or the myelin sheath. Although different proteins are abnormal in different forms of CMT disease, all of the mutations affect the normal function of the peripheral nerves. The gene mutations in CMT disease are usually inherited.
Skin! In epidermis, you have epithelial tissue. In case of dermis, you have connective tissue.
As you may know nerve cells (Neurones) have a layer of fatty Insulation surrounding them called a Myelin Sheath. These a long flat structures projecting from various cells wrap around the Axon. This forms a Discontinuous sheeth meaning it has section that are covered but with gaps in the middle. Ions cannot pass through the membrane of the neurone at parts that are sheethed but only at the gaps. The gaps are what are known… Read More
An epidural hematoma is a pocket of blood that forms immediately outside the dura mater. The dura mater is the fibrous outermost sheath or membrane that encloses the brain and spinal cord.
An impact crater is formed when a missle (projectile) of suffecient mass and kenetic energy impacts the ground. This behavior is illustrated by artillary fire from modern cannons. The air around the missle becomes superheated into plasma and forms a highly energetic envelope around the missle. On impact, this plasma sheath explodes outward displacing the material around it.
WHAT IS the process of myelination and lateralization and their effects on development during this period?
The period in question is pertaining to a child's play years. Myelination is a condition in which myelin forms around nerve cells allowing difficult thought processes to be transmitted. It is especially important during the teen years. Lateralization refers to localizing of functions to the brain, as far as left and right. A child's intellectual direction during adolescence forms predominately through these two processes.
Vitamin B-12 is necessary for the proper formation of red blood cells and transport of oxygen through the body. It is also necessary for neurological health as it forms a necessary component of nerve cell axonal sheathes (myelin).
motor neuron is actually a nerve cell made up of dendrites,axon,shwann cell,mylean sheath,central cell body,nodes of ranvier which carry messages from central nervous system to effectors.......
In Ectomycorrhizae the mycelium forms a dense sheath aka mantle over the surface of the root. From this fungal hyphae extend from the mantle into the soil which increases surface area greatly. On the other hand arbuscular mycorrhizae do not have a dense mantle around the root, but they still have microscopic hyphae that extend into the root.
Nostocales The Nostocales order contains most of the species of cyanobacteria. It includes filamentous forms, both simple or branched, and both those occurring as single strands or multiple strands within a sheath. Jon. Anderson Olympia, Washington
The nerves in the Central Nervious System (CNS) cannot repair themselves. This consists of the brain and spinal cord. Once damaged or cut they will not regrow. The Myelin sheath that wraps most nerves in the CNS (think of tape around a hockey stick) called Oligodendroglia do not repair either. Over time, the nerves in the Peripheral Nervious System (PNS) will repair themselves, as well as the sheath that wraps most of thses cells, called… Read More

A cell membrane forms around each new cell.
Generally no, Stenosing tenosynovitis is also called Trigger finger. The Sheath around the tendon closes in or gets tighter around the tendon. Sometimes nodules forms on tendon and this can get caught on the sheath of the tendon causing a locking or triggering effect on the finger...Hence the name. Carpal tunnel syndrome is a condition where the median nerve in the wrist is compressed causing numbness and tingling in certain fingers but NO triggering and… Read More
Zygomycota, Ascomycota and Basidiomycota are mutualistic with the roots of many plants. Fungal hyphae either forms a sheath around the outside of the roots or actually penetrates the root and enter directly into the root cells. The presence of the fungus increases the surface area of the root so it can absorb more water and nutrients. In return for helping the plant, the fungi uses sugars produced during photosynthesis.

Resistance in series, is additive. If you know the resistance per unit length, just multiply by the distance.
Armbinder is a loose term designating a range of restraint devices primarily used in bondage play (rather than law enforcement, medicine, or psychiatry), their common function being to bind the arms and/or hands to each other or to the body, usually behind the back. The most common form is the monoglove, and in some usage the term functions as if a direct synonym for 'monoglove'; but a wide range of other forms exists (see external… Read More
The earliest ones still around are stromatolites, but there were lots of earlier life forms.
General All living cells have the ability to react to stimuli. Nervous tissue is specialised to react to stimuli and to conduct impulses to various organs in the body which bring about a response to the stimulus. Nerve tissue (as in the brain, spinal cord and peripheral nerves that branch throughout the body) are all made up of specialised nerve cells called neurons. Neurons are easily stimulated and transmit impulses very rapidly. A nerve is… Read More
