The cellular form of prion protein (PrP
) is anchored to the plasma mem-brane of the cell and expressed in most tissues, but predominantly in the
brain, including in the pituitary gland. Thus far, the biosynthesis of PrP
has been studied only in cultured (transfected) tumour cell lines and not in
Chapter 15 provides knowledge of endocrine system. This chapter includes contents: Endocrine glands, hypothalamus and pituitary gland, thyroid and parathyroid glands, adrenal glands, pancreas, other endocrine glands, chemical signals.
Chapter 16 - The endocrine system (part b), this chapter describe structural and functional relationships between the hypothalamus and the pituitary gland; list and describe the chief effects of anterior pituitary hormones; discuss the structure of the posterior pituitary, and describe the effects of the two hormones it releases;...
After completing chapter 34, you will be able to: Describe the general functions of hormones and the endocrine system; identify the hormones released by the pituitary gland, thyroid gland, parathyroid glands, adrenal glands, pancreas, and other hormone-producing organs, and give the functions of each; explain the effect of stressors on the body; describe the causes, signs and symptoms, and treatments of various endocrine disorders.
In contrast to the ingestion of water, its excretion is tightly regulated by physiologic factors. The principal determinant of renal water excretion is arginine vasopressin (AVP; formerly antidiuretic hormone), a polypeptide synthesized in the supraoptic and paraventricular nuclei of the hypothalamus and secreted by the posterior pituitary gland.
Understanding of the neuroendocrine system provides an insight into a wide range of bodily and mental processes. Neuroendocrinology and Behavior brings its readers a concise guide to up-to-date knowledge on the function of the endocrine glands and organs in association with neurotransmitters, neuropeptides, and behavioral manifestations. Various forms of stress response, e.g. anxiety and cognitive changes, have been intrinsic to both ourselves and other species.
(BQ) Part 1 book "Imaging of the brain" presents the following contents: Static anatomic techniques, image and pattern analysis, patterns of contrast enhancement, scalp, surface anatomy of the cerebrum, deep gray nuclei and related fiber tracts, normal brain anatomy, white matter,...
Prolactin is a polypeptide hormone that is synthesized in and secreted from the lactotrophs of the anterior pituitary gland. We are now aware that synthesis and secretion of prolactin is not restricted to the anterior lobe of the pituitary gland, but other organs and individual cells can also produce it. This book provides the headlines to follow a course of cumulated knowledge on prolactin research during the last two-three decades and it may also help us understand some of the concerns that we face today....
Etiology Vasopressin is an antidiuretic hormone normally produced by the posterior pituitary gland. Ectopic vasopressin production by tumors is a common cause of the syndrome of inappropriate antidiuretic hormone (SIADH), occurring in at least half of patients with SCLC.
Compensatory mechanisms, such as decreased thirst, suppression of aldosterone, and production of atrial natriuretic peptide (ANP), may mitigate the development of hyponatremia in patients who produce excessive vasopressin.
Chapter 32 - The endocrine system. The endocrine system includes the organs of the body that secrete hormones directly into body fluids such as blood. Hormones help to regulate the chemical reactions within cells. They therefore control the functions of the organs, tissues, and other cells that comprise these cells. In this chapter you will learn about the processes and organs of the endocrine system.
Understanding of the neuroendocrine system provides an insight into a wide range of
bodily and mental processes, e.g. from water balance to social activity.
Neuroendocrinology and Behavior brings its readers a concise guide to up-to-date
knowledge on the function of the endocrine glands and organs in association with
neurotransmitters, neuropeptides, and behavioral manifestations. In particular, this
volume provides a unique medium for interactions across these multiple levels of the
exploration on neuroendocrinology, behavior, and related disorders....
Common household products –detergents, disinfectants, plastics, and pesticides– contain chemical ingredients that enter the body,
disrupt hormones and cause adverse developmental, disease, and reproductive problems. Known as endocrine disruptors, these
chemicals, which interact with the endocrine system, wreak havoc in humans and wildlife.
People with MEN1 have a very high risk of developing tumors of 3 glands: the pituitary,
parathyroid, and pancreas. About one-third to one-half of people with this condition also
develop adrenal adenomas or enlarged adrenal glands. These usually do not cause any
symptoms. This syndrome is caused by defects in a gene called MEN1. People who have
a family history of MEN1 or pituitary, parathyroid, pancreas, or adrenal cancers should
ask their doctor if they might benefit from genetic counseling.
Oxytocin is secreted naturally by the posterior pituitary—the back portion of a small gland at the brain’s base that
produces hormones—during later pregnancy, labor, and when the baby breastfeeds. Synthetic forms of oxytocin
are found in brand-name products as well as in generic form. In moderate doses, oxytocin produces slow,
generalized contractions of the muscles in the uterus with full relaxation in between. When used for postpartum
hemorrhage, oxytocin takes effect sooner than most other uterotonic drugs, including misoprostol.
(BQ) Part 1 book "Endocrine and reproductive physiology" presents the following contents: Introduction to the endocrine system, endocrine function of the gastrointestinal tract, energy metabolism, calcium and phosphate homeostasis, hypothalamus pituitary complex, the thyroid gland.
