What else can I help you with?
Can undamaged neurons make new connection with damaged neurons?
yes
Do neurons have the ability to replicate?
No, neurons do not have the ability to replicate. Once they are damaged or lost, they cannot be replaced.
Do neurons get replaced in the human brain?
No, neurons in the human brain do not typically get replaced. Once neurons are damaged or lost, they are not usually regenerated or replaced by new neurons.
Are neurons replaced in the human brain?
No, neurons are not typically replaced in the human brain. Once neurons are damaged or lost, they are not usually regenerated or replaced.
Can neurons be replaced in the human brain?
No, neurons cannot be replaced in the human brain. Once neurons are damaged or lost, they typically cannot regenerate or be replaced.
Could damaged neurons in the CNS multiply and grow back?
no
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.
Which group of brain cells are destroyed in paralysis agitans?
In paralysis agitans, which is another term for Parkinson's disease, the group of brain cells that are primarily affected are the dopaminergic neurons in the substantia nigra region of the brain. These neurons are responsible for producing dopamine, a neurotransmitter that helps regulate movement and coordination.
Explain why hands lips and head have so many neurons?
No
What happen If the dorsal respiratory group of neurons in the medulla oblongata were destroyed bilaterally?
If the dorsal respiratory group of neurons in the medulla oblongata were destroyed bilaterally, it would lead to decreased drive for inspiration, resulting in respiratory depression or even respiratory arrest. This group of neurons plays a crucial role in regulating the rhythm and depth of breathing.
What are the only neurons in the body to routinely undergo mitosis?
The olfactory receptor neurons in the nose are the only neurons in the body that routinely undergo mitosis to replace damaged or aging cells. Other neurons in the central nervous system typically do not undergo mitosis and have limited capacity for regeneration.
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
