Chapter 11, Problem 5aCP
Summary Introduction
To review:
Embryonic origin along with parts of adenohypophysis and neurohypophysis of pituitary gland.
Introduction:
The pituitary gland is one of the most important endocrine glands of human body. It is roughly 1.3cm (centimeter) in diameter and is also known as hypophysis. This is attached to hypothalamus of brain by stalk like structure called infundibulum. The pituitary gland can be divided into anterior lobe or adenohypophysis and posterior lobe also known as neurohypophysis. Both the lobes have different structure, functions and embryonic origins.Â

Students have asked these similar questions
Describe the embryonic origins of the adenohypophysis and neurohypophysis, and list theparts of each. Which of these parts is also called the anterior pituitary? Which is called the posterior pituitary?
Describe the locations of, as well as the anatomical and functional relationships between, the hypothalamus and the anterior and posterior pituitary glands.
Although the pituitary gland is often referred to as the master gland of the body, the hypothalamus exerts some control over the pituitary gland. How does the hypothalamus control both anterior and posterior pituitary functioning?
