Which is the ‘master gland’?
The pituitary gland, in the base of the brain, is the most important endocrine gland. Although it is only tiny, it produces hormones that regulate the effects of the other glands. The pituitary gland is connected directly to a region of the brain called the hypothalamus, and so provides the link between the brain and the endocrine system. The pituitary gland produces many important hormones, including growth hormone as well as hormones that cause the sex glands to start secreting their own hormones.
Which gland controls the way the body uses energy?
The thyroid gland produces hormones that control the rate at which chemical reactions take place in the body. The gland is in the base of the neck. Thyroxin is one of the hormones produced by the thyroid gland. It speeds up the production of energy from the food you eat. An underactive thyroid can mean that a person becomes slow and sluggish. Other hormones from the thyroid control the amount of calcium in the bones.
