Two areas of the brain are dedicated specifically to language. Indicate what aspects of language are regulated in each and how damage to each of these regions affects speech.
 
  What will be an ideal response?

Question 2

Compare the hormonal effects of norepinephrine with its function as a neurotransmitter. How do these effects reinforce each other to help an individual survive?
 
  What will be an ideal response?

Answer to q. 1

One area is dedicated to the production of language, coordinating the movements of the vocal structures that allow speech. Damage to this area causes a person to have difficulty forming words, but what they can say makes sense. A different area is dedicated to comprehension, that is, producing speech that makes sense. A person with damage in this area can produce a flow of grammatically connected words, but the content does not make sense.

Answer to q. 2

In both cases, norepinephrine gears an organism up for a burst of activity. The release as a hormone has general effects on physiology, including raising blood sugar, blood pressure, and heart rate. The sympathetic autonomic nervous system also releases norepinephrine as a neurotransmitter, which increases heart rate, depresses digestive activity, and acts on other organs in preparation for fight or flight. This coordinates an increase in the capacity to act quickly, which may allow an organism to escape disaster.

Oh god, I was lost before coming here. Thanksss
