Which statement about the posterior pituitary is correct?
AIt stores hormones made in the hypothalamus
BIt makes the hormones that act on the thyroid
CIt is glandular tissue from the digestive tract
DIt sends its hormones down a duct to the blood
Answer & Solution
Correct answer: A. It stores hormones made in the hypothalamus
1. The posterior pituitary is neural tissue made of axon terminals of hypothalamic neurons.
2. It manufactures nothing of its own and only stores and releases what the hypothalamus made.
3. Thyroid-stimulating hormone comes from the anterior lobe, not the posterior one.
4. Glandular tissue from the primitive digestive tract describes the anterior pituitary, and no pituitary hormone travels by duct.
