Pituitary Gland (Hypophysis) About the size and shape of a pea‚ located in the sella turcica of the sphenoid bone‚ attached to the hypothalamus via a stalk called the infundibulum. It has two major lobes‚ one neural and one glandular. Posterior Lobe (Neurohypophysis) – composed of nervous tissue; releases neurohormones that it receives ready-made from the hypothalamus; oxytocin and anti-diuretic hormone (ADH); released on demand in response to nerve impulses from hypothalamic neurons.

Adrenal gland In mammals‚ the adrenal glands (also known as suprarenal glands) are the triangular-shaped endocrine glands that sit on top of the kidneys. They are chiefly responsible for releasing hormones in conjunction with stress through the synthesis of corticosteroids and catecholamines‚ including cortisol and adrenaline (epinephrine)‚ respectively. Anatomy and function Anatomically‚ the adrenal glands are located in the retroperitoneum situated atop the kidneys‚ one on each side. They are

The thyroid gland is an important organ of the endocrine system and located in front of the neck below the larynx consisting of two lobes on each side of the windpipe. It regulates the physical and chemical processes that occur at the cellular level. It regulates the manner and rate at which the tissues utilize food and natural chemicals for the production of energy and to expend that energy into body heat and muscular energy. The thyroid gland produces hormones from the thyroid tissue cells called

The endocrine system is one of our body systems that plays an important role in living. It comprises of many glands exerting hormones in maintaining the body’s internal environment also known as homeostasis. The endocrine system plays an important role in homeostasis because it maintains growth and development‚ maturation‚ reproduction‚ human behavior‚ metabolism‚ sexual function and controls functions of the tissues. It is partnered with the nervous system since the hypothalamus along with the pineal

The Endocrine System FOCUS: The endocrine system is one of the major regulatory systems in the body‚ along with the nervous system. However‚ the endocrine system responds more slowly‚ and has a longer-lasting‚ more general effect on the body than the nervous system. Endocrine tissues internally produce hormones which are released into the blood‚ where they are carried to target tissue and produce a response. Some hormones bind to receptors on the surface of the cell membrane‚ producing permeability

5/27/2014 ENDOCRINE DISRUPTORS AND HOW THEY AFFECT EVERYTHING “Our Stolen Future” by Theo Colborn is about the health and environmental threats created by man-made chemical contaminants that interfere with hormones in humans and wildlife. In this paper i’ll explain what is an endocrine system‚ what are endocrine disruptors‚ and how endocrine disruptors affect humans. The endocrine system includes all of the glands of the body and the hormones produced by those glands. The glands are controlled

BASIC CONCEPTS ENDOCRINE SYSTEM :- In physiology‚ the endocrine system is a system of glands‚ each of which secretes a type of hormone into the bloodstream to regulate the body. It derives from the Greek words endo meaning inside‚ within‚ and crinis for secrete. The endocrine system is an information signal system like the nervous system. Hormones are substances (chemical mediators) released from endocrine tissue into the bloodstream that attach to target tissue and allow communication among
