How do you think a person would be affected if myelin on his or her neurons was damaged or destroyed and how would you explain it?

Myelin is the insulating "sheath" that surrounds nerves in your body. When the myelin breaks down, false signals make it into the nerves, sometimes causing pain, and sometimes causing muscle spasms.

Can undamaged neurons make new connection with damaged neurons?
yes
Could damaged neurons in the CNS multiply and grow back?
no
What happens if motor neurons are damaged?
Motor neuron involve the muscles. If they are damaged, then the muscle that they are connected to will not work.
What neurons are affected in primary lateral sclerosis?
PLS affects a part of the neuron called the cell body (or soma). Specifically, it is the cell bodies of upper motor neurons that are affected.
What is the process by which axons of healthy neurons adjacent to damaged neurons grow new branches to make up for the damage?
Collateral Sprouting
Explain why hands lips and head have so many neurons?
No
Why the polio virus often causes paralysis of the muscles?
poliovirus invades the nerve cells of the spinal cord and kills the motor neurons. When the motor neurons are destroyed, the muscles they connect to become damaged and weaken. The result is varying degrees of paralysis, including difficulty swallowing
What happen If the dorsal respiratory group of neurons in the medulla oblongata were destroyed bilaterally?
breathing would cease
How does meningitis affect cerebral spinal fluid flow?
damaging or killing neurons and neuroglia in the affected areas
When your hit in the head do you damage the neurons in your brain or the axons?
When you are hit in the head, both neurons and axons can sustain damage. Neurons are the specialized cells responsible for transmitting electrical signals in the brain, while axons are long, slender projections that extend from neurons and transmit those signals to other neurons or tissues. Impact to the head can cause direct damage to neurons and axons, leading to functional impairment or cell death.
How do damaged motor neurons affect muscles?
Often, a disorder of the motor neurons results in progressive muscle atrophy (shrinking and wasting) of some, if not all, the muscles of the body. Muscle twitching (fasciculation) is common among these disorders
Did any ancient civilizations develop myths about tornadoes in order to explain how or why they occur?
They looked like neurons.
