Question

which of the following hormones is produced by the posterior pituitary?
a human growth hormone
b antidiuretic hormone
c oxytocin
d b and c
e none of the above

Explanation:

1. Recall the hormones produced by the posterior pituitary: The posterior pituitary (neurohypophysis) stores and releases hormones produced by the hypothalamus, specifically Antidiuretic Hormone (ADH, also called Vasopressin) and Oxytocin.
2. Analyze Option A: Human Growth Hormone (HGH) is produced by the anterior pituitary, so A is incorrect.
3. Analyze Option B: Antidiuretic Hormone is released by the posterior pituitary, so B is correct.
4. Analyze Option C: Oxytocin is released by the posterior pituitary, so C is correct.
5. Analyze Option D: Since both B (Antidiuretic Hormone) and C (Oxytocin) are produced (released) by the posterior pituitary, D is correct.
6. Analyze Option E: Since D is correct, E is incorrect.

Answer:

D. B and C
