Main Image: The Pituitary gland is a pea-sized endocrine (hormone-producing) gland weighing about 0.5 g situated at the bottom of the skull sandwiched between the optic nerves, in humans. The pituitary gland secretes hormones. Hormones are chemicals that travel through the blood stream.
The pituitary gland is often called the master gland. That is because the pituitary gland produces hormones that regulate other endocrine glands. Some hormones produced by the pituitary gland are: 1. Follicle Stimulating Hormone (FSH): Will be discussed in a later Chapter of the syllabus.2. Luteinising Hormone (LH): Will be discussed in a later Chapter of the syllabus.ome these hormones, called releasing hormones, stimulate the pituitary gland to make other hormones. Others, called release inhibiting hormones, prevent the production of pituitary hormones. An example is growth hormone releasing factor. This causes the production of growth hormone (GH) by the pituitary gland.
