together?2. What is the method in which the endocrine system
undergoes its functions?
Recipe: Endocrine System
DIRECTIONS: 1. The endocrine system is responsible for releasing and regulating hormones;
the nervous system sends signals to release hormones and chemical messengers known as neurotransmitters. The master gland is known as the pituitary gland which is known to make these hormones and control other endocrine glands; it is located at the base of the brain. (maintain stability of internal environment.)
2. The endocrine system is made up of glands that produce and secrete hormones and chemicals that regulate the body. Hormones are chemical messengers that transfer information from one set of cells to another. The major glands in this system are the hypothalamus: located beneath the thalamus – regulates satiety, metabolism and body temperature. Next is the pituitary gland – “the master gland” located at the base of the brain; it produces hormones and controls other glands in the endocrine system. Its mainly known to secrete growth hormones – located in the neck. It regulates the body’s metabolism and helps with bone growth and development, blood pressure, heart rate and digestion. Adrenal gland – located at the top of each kidney. It regulates metabolism, immune system and help cope with stress. Pineal body – located at the middle of the brain – secretes a hormone called melatonin which helps aid in sleep. Reproductive glands – sex hormones development of female and male growth and reproductive functions.

Recipe: Hormones
DIRECTIONS:
1. Hormone- Hormone molecules can be classified in various useful ways. When classified by general function, hormones can be identified as tropic hormones, which are hormones that target other endocrine glands and stimulate their growth and secretion. Sex hormones (hormones that target reproductive tissues), anabolic hormones (hormones that stimulate anabolism in their target cells), and many other functional names. In the endocrine system, secreting cells send hormone molecules by way of bloodstream to signal specific target cells throughout the body.
3. All of many hormones secreted by endocrine tissues can be classified simply as steroid or non-steroid. Steroid hormone molecules are manufactured by endocrine cells from cholesterol, and important type of lipid in the human body.

DIRECTIONS: 4. Nonsteroid hormones (water soluble) do not enter the cell but bind to plasma membrane receptors, generating a chemical signal (second messenger) inside the target cell. Five different second messenger chemicals, including cyclic AMP have been identified. Second messengers activate other intracellular chemicals to produce the target cell response.
5. Hormones produce a variety of responses throughout the body and may be grouped according to their actions, although there is overlap between the groups.
5.1 The endocrine system is a collection of glands that secrete chemical messages we call hormones. These signals are passed through the blood to arrive at a target organ, which has cells possessing the appropriate receptor, they will not connect unless they have the correct receptor, kind of like a lock and key. (22)
5. 2 First there are the metabolic hormones which control the digestion of food, its storage and use. Second are the hormones which regulate the composition of the blood, and hence of all the body fluids. Next are the stress hormones, primarily adrenaline and noradrenaline, which are under the control the autonomic nervous system. The final major group includes those hormones that control other endocrine systems, and therefore interact with the other groups. (23)
Recipe: Organs and Glands of the Endocrine System
1. Prostaglandins2. Pituitary Gland3. Pineal Gland4. Thyroid Gland5. Parathyroid gland6. Adrenal Gland
7. Pancreatic Islet8. Gonads9. Placenta10.Thymus11.Gastric and intestinal mucosa12.Heart
Ingredients:
DIRECTIONS:1. Group of naturally occurring lipid-based substances that act in a hormone like way to affect many body functions, including vasodilation, uterine smooth muscle contraction, and the inflammatory response. Hormones: 16 different prostaglandins falling into 9 structural classes – prostaglandins A-I.
2. Neuroendocrine gland located near base of the brain that has numerous and important regulatory functions; also called the hypophysis. Consists of two separate glands (adenohypophysis and neurohypophysis.)
(1)
DIRECTIONS:3. Endocrine gland located in the diencephalon and thought to be involved with regulating the body’s biological clock; produces melatonin.
4. Hormone that accelerates catabolism of glucose. Hormones: Triiodothyronine, Tertaiodothyronine, and Calcitonin.
5. Endocrine gland located in the neck on the posterior aspect of the thyroid gland; secretes parathyroid hormone. Hormones: Parathyroid Hormone.
6. Endocrine gland that rests on the top of each kidney; made up of cortex and medulla regions. Hormones: Aldosterone, Cortisol, Adrenal Androgens, Adrenal Estrogens, Epinephrine, and Norepinephrine.
7. Endocrine portion of the pancreas; made up of alpha and beta cells; among others; source of insulin and glucagon. Hormones: Glucagon, Insulin, Somatostatin, Pancreatic Polypeptide.
8. Sex glands in which reproductive cells are formed; ovaries in women, testes in men.
9. Structure that anchors the developing fetus to the uterus and provides a “bridge” for the exchange of nutrients and waste products between the mother and developing baby.

DIRECTIONS:10. Endocrine gland located in the mediastinum; vital part of the body’s Immune system. Hormones: Thymosin and Thymopoietin.
11. The mucosa lining of the gastrointestinal (GI) tract, like the pancreas, contains cells that produce both endocrine and exocrine secretions. Hormones: Gastrin, Secretin, Cholecystokinin-pancreozymin (CCK), and others, have important regulatory roles in coordinating the secretory and motor activities involved in the digestive process.
12. Organ of circulatory system that pumps the blood; composed of cardiac muscle tissues, a specific area in its wall contains some hormone-producing cells. The cells produce a hormone called atrail natriuretic hormone.
