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

new A number of factors influence the brain structures and functions associated with the motivation to refrain from using drugs. The dynamics involved include intrinsic and extrinsic motivation‚ heredity‚ and environmental forces. In general‚ internal motivation is considered to be associated with long-term behavior modification‚ whereas the successful outcome of external motivation can be short lived (Pubs.niaaa.nih‚ 2010).Motivational assessment suggests a considerable challenge.

May be you will show such behavior because of hereditary once in a day but it is always there. However‚ the behavior can change which creates the contrast from heredity and such cases arise in the case of the changes in the hormonal balance in the body because of diet changes.

separated by a middle ridge (little ravine). I observed the gland to be composed of two tissue types‚ an adenohypophysis (anterior lobe) derived from buccal ectoderm and a neurohypophysis (posterior lobe) also called pars nervosa derived from neural ectoderm. The adenohypophysis contains mainly cords of glandular epithelium surrounded by blood vessels and some C.T. The major anterior portion of this lobe is called pars distalis. A smaller portion‚ pars intermedia‚ lies between the pars distalis and the
