Question 6

Tropic hormones of the anterior pituitary include TSH, FSH, ACTH, and LH.

Tropic hormones are those that stimulate other glands to release hormones. In this case, TSH, FSH, ACTH, and LH are all hormones produced by the anterior pituitary that regulate the activities of other endocrine glands.

A) ACTH, LH, GH, and TSH

This option is incorrect because, although ACTH, LH, and TSH are tropic hormones, GH (growth hormone) is not classified as a tropic hormone; it directly affects tissues rather than stimulating other glands.

B) Estrogen, ACTH, LH, and FSH

This option is incorrect since estrogen is not produced by the anterior pituitary and does not belong to the tropic hormone category. While ACTH, LH, and FSH are tropic hormones, this choice does not accurately reflect the correct set.

C) TSH, FSH, ACTH, and LH

This option is correct because TSH (thyroid-stimulating hormone), FSH (follicle-stimulating hormone), ACTH (adrenocorticotropic hormone), and LH (luteinizing hormone) are all produced by the anterior pituitary and function to stimulate other endocrine glands.

D) TSH, LH, vasopressin, and FSH

This option is incorrect because, while TSH, LH, and FSH are tropic hormones, vasopressin (also known as antidiuretic hormone) is not produced by the anterior pituitary; it is produced by the hypothalamus and released from the posterior pituitary.

Conclusion

The correct answer is option C, as it accurately lists the tropic hormones produced by the anterior pituitary gland. Each of these hormones plays a critical role in regulating the function of other endocrine glands, while the other options either include non-tropic hormones or misclassifications, failing to provide the correct set of anterior pituitary hormones.
