Endocrine system Endocrinology is the study of chemical communication systems that provide the means to control a huge number of physiologic processes. Like other communication networks‚ endocrine systems contain transmitters‚ signals 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

the adrenal medulla‚ which is in the inner adrenal gland. This gland sits atop the kidney. When put under stress this gland is stimulated by the nervous system and releases adrenaline into the blood stream. The release of adrenaline is a three step process. First‚ the hypothalamus produces hormones that stimulate the pituitary gland. Next‚ the pituitary gland then produces corticotropin hormones which are hormones that stimulate the adrenal glands that eventually produce adrenaline. In 1895

EXERCISE 27 Functional Anatomy of the Endocrine Glands Gross Anatomy and Basic Function of the Endocrine Glands 1. Both the endocrine and nervous systems are major regulating systems of the body; however‚ the nervous system has been compared to an airmail delivery system and the endocrine system to the pony express. Briefly explain this comparison. The nervous system is a lot more fast acting and more rapid action occurs when compaired to the endocrine and the slow path through the blood stream

What 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

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

The endocrine system is very dynamic and has ties to most‚ if not all of the other major systems of the body. It is responsible for production of hormones and the regulation of them as well. These hormones act as chemical messengers within the body. Through several differing mechanisms‚ they are able to trigger very specific responses in target cells or organs. This is what enables the endocrine system to guide growth‚ development‚ reproduction‚ and behavior‚ among many others as well.

Are Apocrine Glands? Apocrine glands are located in the skin‚ breasts‚ eyelids‚ and ears. They are a type of exocrine gland‚ which are glands that secrete hormones into a duct. Counterparts of exocrine glands are endocrine glands that secrete their hormones directly into the bloodstream. Certain endocrine glands also release hormones called pancrines that affect only specifically targeted cells very close to where they are released. Examples of endocrine glands are the pituitary gland‚ pancreas‚
