Accepted Answer

Insulin; $$	ext{Glucose}_{	ext{blood}} ightarrow 	ext{Glucose}_{	ext{cell}}$$

Question 9

Which hormone stimulates the thyroid gland to release thyroxine, and what is the effect of thyroxine on metabolism?

Accepted Answer

Thyroid stimulating hormone (TSH); increases metabolism

Question 10

Which structure connects the two hemispheres of the cerebrum and what is its primary function?

Accepted Answer

Hearing

Question 17

Which hormone is released by the ovary and what is its primary role in the body?

Accepted Answer

Estrogen; regulation of female reproductive system

Question 18

Which structure in the diencephalon is responsible for producing melatonin, and what is the effect of melatonin on the body?

Accepted Answer

Pineal gland; promotes sleep

Question 19

Which cranial nerve structure receives action potentials related to the sense of smell?

Accepted Answer

Olfactory bulbs

Question 20

A multi-step scenario: A patient is experiencing increased blood glucose, rapid heartbeat, and difficulty sleeping. Which glands and hormones are most likely involved, and what is the sequence of events?

Accepted Answer

Adrenal gland (cortisol and epinephrine) and pineal gland (melatonin); stress increases cortisol and epinephrine, which raise glucose and heart rate, while reduced melatonin disrupts sleep
