to know about the Pituitary Gland Anatomy & Physiology II BIO144-1003B-06 It is interesting to find out about the pituitary glands in more detail. The pituitary glands are just one major part of the endocrine system. The pituitary glands secrete hormones to the bloodstream. It has two different categories‚ such as the anterior lobe and the posterior lobe. The anterior lobe secretes different hormones that are important to the human everyday life. Prolatin‚ growth hormone‚ adrenocorticotropic

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.

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 cells. Hormones regulate many functions of an organism

The Pituitary Gland and Dwarfism The Pituitary Gland is situated at the base of the brain and it produces hormones which control growth. Too large an amount of these hormones causes giantism‚ a condition where facial features‚ hands‚ etc. become abnormally large. Too little causes dwarfism‚ where the overall stature of a person is very small. Dwarfism is the condition of being undersized‚ or less than 127 cm (50 in) in height. Some dwarfs have been less than 64 cm (24 in) in height when fully

and receivers that are called‚ respectively‚ hormone producing cells‚ hormones and receptors. The first step in understanding endocrinology is to explore the meaning of such terms as hormone‚ receptor and target cell‚ and to obtain an understanding of how chemical communication is controlled | Hormones‚ Receptors and Target Cells | What exactly are hormones and how are they different from "non-hormones"? Hormones are chemical messengers secreted into blood or extracellular fluid by one cell

HORMONES Hormones are a class of regulatory biochemicals produced in all multicellular organisms by glands‚ and transported by the circulatory system to a distant target organ to coordinate its physiology and behavior. They serve as a major form of communication between different organs and tissues. Hormones regulate a variety of physiological and behavioral activities‚ including digestion‚ metabolism‚ respiration‚ tissue function‚ sensory perception‚ sleep‚excretion‚ lactation‚ stress‚ growth and
