Question

question 3 (2.5 points)
the thymus gland secretes a hormone called ______.
○ estrogen
○ thymosin
○ insulin
○ glucagon
question 4 (2.5 points)
the posterior pituitary is also known as the ______.
○ neurohypophysis
○ adenohypophysis
○ hypophysis

Explanation:

Question 3

To solve this, we recall the function of the thymus gland. The thymus secretes thymosin, which plays a role in T - cell development. Estrogen is related to the reproductive system (ovaries), insulin is from the pancreas (regulates blood sugar), and glucagon is also from the pancreas (raises blood sugar). So the correct option is thymosin.

We need to know the alternative name of the posterior pituitary. The posterior pituitary is also called the neurohypophysis. The adenohypophysis is the anterior pituitary, and hypophysis is a general term for the pituitary gland.

Answer:

B. thymosin (assuming the options are labeled as A. estrogen, B. thymosin, C. insulin, D. glucagon)
