7. a student is preparing for a school play and feels very excited and energetic. which hormone is likely contributing to the students excitement and energy, and which gland produces it?\n8. a student stays up late studying for exams and finds it difficult to stay focused and alert the next day. which neurotransmitter might be in low supply due to lack of sleep, and what is its role in the nervous system?\n9. a student feels very relaxed and sleepy after eating a large meal. which part of the autonomic nervous system is responsible for this relaxed state, and what is its primary function?\n10. a student has been experiencing difficulty falling asleep and staying asleep, which affects their mood and cognitive performance during the day. which brain structure and neurotransmitter are primarily involved in regulating sleep, and how might they be contributing to the students sleep issues?

Answer

Brief Explanations:

  1. Adrenaline (epinephrine) is likely contributing to the excitement and energy. It is produced by the adrenal glands and prepares the body for a "fight - or - flight" response.
  2. Dopamine is important for focus and alertness. Lack of sleep can deplete dopamine levels. It plays a role in the brain's reward and motivation system.
  3. The parasympathetic nervous system is responsible for the relaxed state after eating. Its primary function is to promote "rest - and - digest" activities like slowing the heart rate and aiding digestion.
  4. The pineal gland produces melatonin which regulates the sleep - wake cycle. Serotonin is also involved as it can be converted to melatonin. If the pineal gland is not producing enough melatonin or serotonin levels are off, it can cause sleep issues.

Answer:

  1. Hormone: Adrenaline, Gland: Adrenal glands
  2. Neurotransmitter: Dopamine, Role in nervous system: Involved in reward and motivation, helps with focus
  3. Part of autonomic nervous system: Parasympathetic nervous system, Primary function: Promotes rest and digest activities
  4. Brain structure: Pineal gland, Neurotransmitter: Melatonin (produced from serotonin), Contribution to sleep issues: Insufficient production of melatonin by the pineal gland or imbalances in serotonin can disrupt sleep - wake cycle
