Notes / Explanation
The gland that is known as the master gland of the human body is the pituitary gland, a very small gland located at the base of the brain, which despite its tiny size plays an extremely important role in controlling many of the functions of the body. The body contains a number of glands that produce substances called hormones, which are released into the blood and which act as chemical messengers that travel to different parts of the body and control and regulate various important processes, such as growth, the balance of substances in the body, and many other functions. This system of glands and hormones is one of the main systems by which the activities of the body are coordinated and controlled. The pituitary gland is called the master gland because, in addition to producing hormones of its own that have important effects, it also controls and directs the activity of several of the other glands of the body, sending out hormones that instruct these other glands when and how much of their own hormones to produce. In this way the pituitary gland acts as a kind of control centre for much of the hormonal system, regulating the work of the other glands and thereby influencing a great many of the processes of the body. Among the important functions influenced by the pituitary gland are the growth of the body, so that it plays a key role in determining how a person grows, as well as the regulation of various other glands that themselves control important processes. Because of its central and controlling role, any disorder of the pituitary gland can have wide-ranging effects on the body, affecting growth and many other functions, which shows the importance of this tiny but powerful gland. The pituitary gland itself is closely connected with a part of the brain, which helps to link the hormonal system with the nervous system, so that the body's activities are coordinated. The study of the glands and hormones and their role in controlling the body is an important part of the study of the human body. For PPSC and other competitive examinations, the key points to remember are that the gland known as the master gland of the human body is the pituitary gland, that it is a very small gland located at the base of the brain, that it is called the master gland because it controls and directs the activity of several other glands as well as producing important hormones of its own, and that it plays a key role in growth and many other bodily processes.
