These are made in the hypothalamus and stored in the posterior pituitary. On the other hand, the hormones released by the posterior pituitary help in the proper functioning of the kidney and uterus muscle contraction. The posterior pituitary – Stores and releases hormones produced by the hypothalamus. In many animals, these lobes are distinct. The bloodstream transports the pituitary hormones to other endocrine glands, such as the thyroid gland. The anterior pituitary gland secretes 7 hormones: follicle -stimulating hormone, luteinizing horomone, adrenocorticotropic horomone, thyroid -stimulating horomone, prolactin, endorphins, and growth hormone. It controls all hormones that we need to function and develop normally. Anterior pituitary secretion of ACTH, TSH, and the gonadotropins (FSH and LH) is controlled by negative feedback inhibition from the target gland hormones. Identify the six hormones produced by the anterior lobe of the pituitary gland, their target cells, their principal actions, and their regulation by the hypothalamus The hypothalamus–pituitary complex can be thought of as the “command center” of the endocrine system.

It is situated in a bony structure called the Pituitary fossa, just below the hypothalamus, close to the optic nerve. It is often referred to as the ‘Master Gland’ because it produces some of the important hormones in the body. There are four hormones secreted by the anterior pituitary gland that control the functions of other endocrine glands. It is called the ‘Master Gland’ since it produces eight hormones, which act on other endocrine glands such as ovaries, testes, adrenocortical region, thyroid and mammary gland to stimulate their hormone production. Posterior pituitary Hormones. Tests of the pituitary gland and pituitary function include: Hormone levels: pituitary hormones are released in pulses and levels fluctuate during the day. The anterior lobe, which makes up about 80% of the gland, secretes these hormones: Adrenocorticotropic hormone (ACTH) causes the adrenal glands to produce steroid hormones, especially cortisol. The anterior pituitary produces hormones used in the reproductive process. The pituitary gland sits below the brain in a midline pocket or fossa of the sphenoid bone known as the sella turcica, imaginatively named by anatomists because of its likeness to a Turkish horse saddle.
