Video transcript

Hey, everyone. Let's take a look at this question together. A lesion of the pituitary gland could cause the over secretion of which hormone is it? Answer choice. A glucagon, answer choice. B, insulin, answer choice, C growth hormone or answer choice. D all of the above. Let's work this problem out together to try to figure out which of the following answer. Choices is a hormone that would be over secreted as the result of a lesion of the pituitary gland. So in order to solve this question, we have to recall what we have learned about the pituitary gland and how a lesion of the pituitary gland would result in the over secretion of a specific hormone. And we can recall that an example of what would happen if there is a lesion in the pituitary gland is a condition called acromegaly, which acromegaly is a hormone disorder that is caused by an overproduction of growth hormone, which we know that growth hormone is the hormone that is produced by the pituitary gland and too much growth hormone. Or that over secretion of growth hormone can result in increased bone size or increased height. Which means that a lesion of the pituitary gland could cause the over secretion of answer choice C growth hormone, which is the correct answer. And all other answer choices are incorrect. Since we can also identify that both Glucagon and insulin are hormones that are secreted by the pancreas and not the pituitary gland. So answer choice C is the only correct answer choice. I hope you found this video to be helpful. Thank you and goodbye.
