Which of the Following Can Occur in the Process of Negative

Question

Which of the following can occur in the process of negative feedback
A)TSH inhibits thyroid hormone secretion by the thyroid gland.
B)Thyroid hormone inhibits TSH secretion by the anterior pituitary.
C)Thyroid hormone directly inhibits further thyroid hormone secretion by the thyroid gland.
D)TRH inhibits TSH secretion by the anterior pituitary.

Accepted Answer

Negative feedback occurs when a product of a process inhibits its own production by suppressing one of the steps leading up to it. In this case, thyroid hormone (the product) inhibits the secretion of TSH (thyroid-stimulating hormone) by the anterior pituitary, which is a classic example of negative feedback in the endocrine system.
