○ subarachnoid space
○ meninx
○ dural space
○ epidural space

3 multiple choice 1 point
sound is simply pressure disturbances from vibrating objects.
○ true
○ false

Explanation:

Question 1

The parasympathetic nervous system exits the central nervous system from the brain (via cranial nerves) and the sacral spinal cord. The sympathetic nervous system exits from the thoracic and lumbar spinal cord.

None of the given options (subarachnoid space, meninx, dural space, epidural space) create cerebrospinal fluid. The choroid plexus (not listed here) is responsible. But if we assume a possible error and re - evaluate, maybe a mis - option. However, among the given, none is correct. But if we have to choose from the given, perhaps a mistake. Wait, maybe the options were miswritten. But based on standard knowledge, the correct structure (choroid plexus) is not here. But if we consider the options, maybe a typo. But as per the given, no correct option. But maybe the question had a typo. However, if we proceed, the answer would be none, but since we have to choose from the given, perhaps the question is wrong. But maybe I made a mistake. Wait, the subarachnoid space contains CSF, meninx is a membrane, dural space and epidural space are spaces. So no correct option. But maybe the original question had a different set. But as per the given, no correct answer among the options. But perhaps the user made a typo.

Sound is indeed pressure disturbances (waves) that are produced by vibrating objects. These pressure waves travel through a medium (like air, water, etc.) and are detected as sound.

Answer:

B. Parasympathetic nervous system
