1. In one terrifying second the lights in the expansive basement file room went dark.
2. The young file clerk was instantly disoriented—unable to even see her hand in front of her face.
3. She waited a few long seconds and she was finally able to make out the shadowy outlines of file cabinets.
4. She then became aware of strange noises around her.
5. Tried as she did, she was unable to discern the source of the noises or even what they were.
6. She decided that she had to find her way out of the shadowy basement.
7. Though she could not see her feet, she carefully put one foot in front of the other and began to walk,
8. Her arms outstretched to avoid bumping into the filing cabinets, she slowly worked her way through the maze of cabinets.
9. As she continued her dark odyssey, she suddenly stopped.
10. One of those unrecognizable noises sounded terribly familiar.

23. She braces herself for the worst. And then…
24. her five year old son jumps onto the bed…”Mommy it’s time to get up!!”
25. Damn these nightmares

1) Please discuss the division of the peripheral nervous system most likely critically active in the underlined portion of Line 22.

2) Please describe the neural pathway (from PNS to CNS) that makes Line 21 possible.

Answer 1

Please discuss the division of the peripheral nervous system most likely critically active in the underlined portion of line 22.

Parasympathetic nervous system of ANS of the peripheral nervous system most likely critically active in the underlined portion of line 22. Parasympathetic nervous system helps to calm down after the ending of stressful situations.

Please describe the neural pathway (from PNS to CNS) that makes line 21 possible.

Both PNS and CNS work together to create a response to the stimuli and the state of being in the environment. The preganglionic neuron of the CNS synapses with a postganglionic neuron of the parasympathetic nervous system. CNS has brain and spinal cord as the comment station which mediate the instructions via motor nerves to both visceral and sensory organs. Sound waves travel from receptors of organ of Corti in the cochlear hair cell are carried via vestibulocochlear nerve to CNS. Sound intensity decreases with increase in distance because that the same amount of energy is spread over a greater area which explains the line 21 possible and why the sounds fade away as you move farther from the source.
