Question
Which of the following correctly describes a difference between the anterior and the posterior pituitaries?Multiple choice question.The anterior pituitary secretes hormones, while the posterior pituitary does not.The anterior pituitary is found in all vertebrates, while the posterior pituitary is only found in birds and mammals.The have different embryonic origins.
Solution
The correct answer is "They have different embryonic origins."
Here's why:
-
Both the anterior and posterior pituitaries secrete hormones. The anterior pituitary secretes hormones such as growth hormone, thyroid-stimulating hormone, and adrenocorticotropic hormone. The posterior pituitary stores and releases hormones produced in the hypothalamus, such as oxytocin and vasopressin.
-
Both the anterior and posterior pituitaries are found in all vertebrates, not just birds and mammals. They are part of the endocrine system, which is a system of glands that produce and secrete hormones directly into the circulatory system.
-
The anterior and posterior pituitaries do have different embryonic origins. The anterior pituitary develops from an outpouching of the oral cavity called Rathke's pouch, while the posterior pituitary develops from a downgrowth of the brain. Therefore, this statement is correct.
