Question

Depressants slow down the sympathetic nervous system resulting in ______.

impaired memory
less self-awareness
slurred speech and slower reactions
all of the above

Answer 1

Well the sympathetic nervous system is part of the peripheral nervous system, which does not include higher-order processes like memory and awareness. I would say its slurred speech and slower reactions due to a lowered muscle excitability.

However, it is plausible that depressants also act on the CNS, but that's not how the question phrases it.

Let me know if this makes sense!

Answer 2

It doesn't to be honest

Answer 3

PNS contain all your peripheral nerves, including those needed for sensing and activating your skeletal muscles. In addition it controls your bowls (smooth muscle), your secretory glands (i.e. exocrine), which can collectively be called the autonomic nervous system (sympathetic + parasympathetic). PNS = Autonomic NS + Somatic NS

Answer 4

So your awareness and memory are all in your brain, which is part of your central nervous system (which also includes the spinal cord). This is separate from the peripheral nervous system (which include all the nerves going to and from the brain/spinal cord)

Answer 5

Yeah there's a lot of hierarchy here, but just focus on the main points: the sympathetic nervous system is in the periphery (i.e. muscles and senses).

Answer 6

C is the only option that focuses on its effects of muscles
