Video transcript

Hey, everyone. Let's take a look at this question together. The adrenal cortex secretes the following hormones, except which is it? Answer choice. A adrenal corticotropic hormone or ac th answer choice B androgens. Answer choice C cortisol or answer choice D Aldo, let's work this problem out together to try to figure out which of the following answer. Choices is a hormone that is not secreted by the adrenal cortex. So in order to solve this question, we have to recall what hormones the adrenal cortex secretes to determine which of the following is not one of them. And we can recall that the adrenal cortex is responsible for the secretion of aldosterone cortisol androgens and estrogens as well as adrenaline or epinephrine. So looking at our answer choices, we can eliminate answer choice. D aldosterone, answer choice, C cortisol and answer choice B androgens. Since those are hormones secreted by the adrenal cortex, leaving us with an choice. A as the only remaining answer choice. Since answer choice, A adrenal corticotropic hormone is not secreted by the adrenal cortex and instead is secreted by the anterior pituitary gland. So answer choice A is the correct answer. I hope you found this video to be helpful. Thank you and goodbye.
