Anterior Lobe (Adenohypophysis) – composed of glandular tissue; manufactures and releases its own hormones as a result of stimulation by releasing hormones from the hypothalamus; called the master endocrine gland; releases 6 hormone products which all function via second messenger systems. Four of the six are hormones that regulate the functioning of other endocrine

The endocrine system The endocrine system is a collection of ductless glands which are positioned through the whole body. The endocrine glands pass their secretions of hormones directly into the blood stream so that they are always adjacent to blood vessels. Hormones are chemicals in the body produced and secreted in the body that regulate the function of a particular tissue or organ (Bing dictionary). These chemical messengers transfer information from one set of cells to another. Despite many

below. | Hormone | Functions | Adrenocorticotropic hormone (ACTH) | ACTH stimulates the cortex to secrete hormones called glucocorticoids. Like cortisol. Which regulates glucose‚ protein‚ and fat metabolism‚ and response to stress. | Antidiuretic hormone (ADH) | ADH regulates water retention in the kidneys‚ reduces urine volume‚ and helps prevent dehydration. Also a brain neurotransmitter. | Follicle stimulating hormone (FSH) | The pituitary secretes FSH. It stimulates the sex hormone estrogen

The endocrine system is made of a series of glands that produce chemicals called hormones. Like many medical terms‚ it originates from the Greek words "endo" meaning inside‚ within‚ and "crinis" for secrete. The endocrine system is an information signal system similar to the nervous system‚ yet its effects and mechanisms are different

The foundations of the Endocrine System consist of hormones and glands. These glands are ductless and their secretions are sent through the bloodstream. Endocrine glands also control bodily metabolic activity. The major glands that make up the human endocrine system are the hypothalamus‚ pituitary‚ thyroid‚ parathyroids‚ adrenals‚ pineal body‚ the pancreas‚ and the reproductive glands‚ which include the ovaries and testes. The endocrine system has three basic functions‚ regulate metabolic functions
