Question

Please read the numbered line story below. Based upon your knowledge and understanding of anatomy and physiology as presented in this course, please provide comprehensive responses to each question presented.

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.
11. The sound of labored breathing, dragging chains, and a gait characterized by a terribly dragging foot on the cold concrete floor, a low moaning growl, menacingly whispering her name.
12. She is now outside in a thick forest.
13. Running as fast as she can the sounds of chains and moaning racing behind her.
14. Her heart is pounding, eyes wide, a heightened sense of terror begins to consume her but she continues to run.
15. Her legs begin to ache.
16. It is becoming harder and harder to keep up the pace.
17. The menacing sounds of chains and moaning is getting closer and closer.
18. Finally, she can run no more.
19. She falls to the ground.
20. As she is breathing heavily, gasping for air, the terrifying sounds of her pursuer get closer and closer.
21. She feels vibration of the ground decrease as the monster seems to move away from her.
22. She calms, she begins planning her next moves...but then the vibrations increase
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. It was just a nightmare

*each number represents the line that is stated in the question below. Use the specific line to answer those questions using the knowledge about the A&P.

QUESTION 5

Please discuss the division of the peripheral nervous system that is likely most critically active in line 14.

QUESTION 6

Line 3 is demonstrative of an important characteristic of life. Please identify and provide an appropriate discussion of this important characteristic of life.

QUESTION 7

Please provide a detailed discussion of the physiology most likely associated with lines 15, 16, and 18.

QUESTION 8

Lines number 4 and 5 are demonstrative of at least two critical functions of the nervous system. Please provide a brief discussion of those two functions.

Answer 1

QUESTION 5

Please discuss the division of the peripheral nervous system that is likely most critically active in line 14.

The division of PNS included in line 14 is autonomic nervous system.PNS is divided into somatic and ANS. ANS comprises sympathetic and parasympathetic nervous system. The physiological event mentioned in line 14 is innervated by sympathetic nervous system or flight-or-fight response.

QUESTION 6

Line 3 is demonstrative of an important characteristic of life. Please identify and provide an appropriate discussion of this important characteristic of life.

The major characteristic mentioned in line 3 is responsiveness to the environment/stimuli.

Human eye takes minutes to hours to get adapted to darkness. It roes by adjusting the optimal sensitivity to low light conditions.The quicket vision gain after few minutes of darkness is aided by rhodopsin, a photopigment used by rods.

QUESTION 7

Please provide a detailed discussion of the physiology most likely associated with lines 15, 16, and 18.

Muscle fatigue. Adrenaline rush due to percieved threat causes vasoconstriction throughout the body which makes lesser availability of blood to muscles leads to aches and heavier.

QUESTION 8

Lines number 4 and 5 are demonstrative of at least two critical functions of the nervous system. Please provide a brief discussion of those two functions.

The critical functions of nervous system mentioned in line 4 and 5 are sensory input and information processing and the another major function of NS also include motor output. Peripheral nervous system responsible for sensory input and motor input via afferant and efferent nerves. PNS convey the information to CNS regarding the state of the body and the external environment for processing of insformation and to recieve instructions.
