Question

Nervous System (answer them all with "just few words no need for details" and I will rate you.

1-What role do basal nuclei play in the regulation of muscle tone? In Parkinson’s disease, neurons involved in motor commands die off. What are some characteristics of an individual with Parkinson’s disease? What neurotransmitter’s concentration declines in the basal nuclei as a result of the loss of these neurons? How is muscle tone affected by the decline in this neurotransmitter? How is Parkinson’s disease treated?

2-What does it mean that the thalamus is a “relay station”? The thalamus and basal nuclei have completely opposite effects on muscle tone. Can you explain this contrast? If pain were sensed in the thalamus, would there be any indication of where it’s coming from? How could this emphasize the importance of the parietal lobe?

3-The thalamus works by filtering 98% of sensory information. Given your knowledge of neurons, how do you think the thalamus “filters out” this information? How could an impairment in the thalamus’ filtering capacity of sensory information lead to the symptoms seen in attention deficit hypersensitivity disorder (ADHD)?

Explanation / Answer

1) answer.

-The role of basal nuclei is to give the response to the external stimuli.

-The main characteristics of an individual with the parkinson disease is rigidity of the muscle, tremor and slowness of the movement, speech problem.

-In the basal nuclei it sometimes may fails to stop or suppress the movements which are not necessary and they are too much inhibited are cannot perform the involuntary action which will leads to the slowness of the movement and may result in the disease known as parkinson.

-By passing the chemical dopamine into the brain
