What cells produce the myelin sheath?Myelin SheathThe myelin sheath wraps some neuron's axons to increase the speed at which they pass electrical signals. The myelin sheath also works to protect and insulate axons. Axons are wire-like extensions on the neuron responsible for carrying signals away...
What cells form the myelin sheath of the peripheral nervous system? Which portion of the peripheral nervous system is associated with carrying impulses from the central nervous system to the regions of the body? a. Afferent. b. Autonomic. c. Efferent. d. Somatic. e. Voluntary. ...
<p><strong>Step-by-Step Solution</strong></p><p>1. <strong>Identify the Cells that Produce Myelin Sheath</strong>: - The myelin sheath is produced by different types of cells depending on whether it is in the central nervous system (CNS) or the periph
What is lumbar scoliosis, convex to the right? What type of cells make up the skeletal-muscle system? What is dorsal kyphosis? Which type of muscle causes voluntary movement? What vertebrae attaches the axial and the appendicular skeleton?
In multiple sclerosis, the immune system's T cells attack the myelin sheath. By attacking myelin, the immune system in a person with MS causes inflammation and degeneration of the myelin that can lead to demyelination, or stripping of the myelin covering of the nerves. It can also cause scar...
The demyelinating form of Guillain-Barre syndrome destroys the protective covering of the peripheral nerves (myelin sheath), preventing the nerves from transmitting signals to the brain. Guillain-Barré syndrome can occur in children, but the number of people who develop the syndrome increases as peop...
Oligodendrocytes produce and maintain the myelin sheath that coats and insulates the axon, making electrical conduction more efficient. Ependymal cells produce CSF (cerebrospinal fluid), which is located within the ventricles of the brain and in the subarachnoid space that surrounds the brain and spina...
Myelin sheath is an insulating layer around the nerves that allows electrical impulses to transmit quickly and efficiently along the nerve cells. Adeficiency can interfere with this process, causing the impulses to slow. Vitamin B6 is also responsible for the metabolism of neurotransmitters like GABA...
Long nerve fiber that conducts away from the cell body of the neuron Dendrites A branched protoplasmic extension of a nerve cell that conducts impulses from adjacent cells inward toward the cell body. A single nerve may possess many dendrites. Also called dendron. Common Curiosities What distinguish...
