An endocrine gland is a gland that comes from the endocrine system which secrets its products like hormones straight into the blood stream without passing through a duct, these endocrine glands are found in the pituitary gland thyroid gland testes ovaries pancreas adrenal gland, parathyroid gland and hypothalamus. (1)The two main classes of hormones are either steroids or modified amino acids, peptides and proteins. Adrenaline can effect a person’s body in different ways as it can cause a person’s

MELATONIN, IMMUNITY AND STEROIDS ABSTRACT Melatonin is the secretion of pineal gland and a broad range of physiological functions are modulated by this hormone. Available finding of research shows that it is an immunomodulatory and anti-inflammatory hormone. In this review, melatonin and its interactions with immune system as well as steroids have been discussed. The immune system protects the body from microorganisms present all around the environment. The anti-inflammatory nature of melatonin connects

INTRODUCTION The pituitary gland is a central endocrine organ that regulates basic physiological functions incuding growth, reproduction and metabolic homeostasis. It situates at the base of the brain, under the optic chiasm, inside a depression on the upper surface of the sphenoid bone, the sella turcica1 (Fig.1). Fig. 1 The pituitary is a small gland found inside the skull just below the brain and above the nasal passages, which are above the fleshy back part of the roof of the mouth

Abstract: The possibility of ACTH being involved in the peroxidase -ascorbate system for the synthesis of progesterone.Rapid depletion of AA under the action of ACTH is known to be a donor in peroxidase reaction. Key Words: Adrenal, ACTH, Hypophysectomy,Peroxidase-Ascorbate System, Progesterone Introduction: ACTH has a major role in the synthesis of progesterone which is known to be a precursor of several steroid hormones including androgens,estrogens and corticoids (Gorbman & Bern,1974).ACTH

Hypothalamus Gland Hormones and Their Functions Katherine M. Gaub Western Dakota Tech Hypothalamus Gland Hormones and Their Functions The Hypothalamus gland is responsible for regulating certain metabolic processes and other activities of the autonomic nervous system such as, controlling the body temperature, hunger, thirst, fatigue, sleep, attachment behavior, and circadian rhythms. This gland, which is about the size of an almond, is located at the base of the brain and is near the Pituitary gland

Crystalyn Poppert BIO202- Amy Bell September 1, 2015 Endocrine Written Assignment 1.) The different methods of intercellular signaling are gap junctions, local/paracrine hormones, and endocrine hormones. Gap junctions are direct connections that permit electrical and chemical signals to pass between cells. Tunnels that directly link cells. For example, the heart allows ions to flow directly from one heart cell to another. Local/paracrine hormones are short distance connections of hormone communication

This tumor is not considered cancerous but instead considered a benign. It only becomes cancerous if it is associated with other disorders such as MEN II (multiple endocrine neoplasia or Neurofibromatosis. In most cases the tumor is found only because of other screenings were being completed. When this is the case it is always best to inform other family members to get a screening completed especially if they are suffering

The central nervous system, or endocrine system, is responsible for the “fight or flight” response in the body (Pietrangelo); the body will use its energy resources to prepare to fight for survival, or flee. This occurs as a result of the hypothalamus in the brain signalling a release of hormones, cortisol and epinephrine, to provide a burst of energy for running from danger. Cortisol and epinephrine cause the liver to produce more glucose (sugar). As a result of chronic stress, extreme levels of

“All children, except one, grow up.” The sentence you just read is the opening sentence of Peter Pan - a fictional novel by James Matthew Barrie. Peter Pan is a fantasy with many themes like growing up and motherhood. The main characters consist of Peter Pan, Wendy Darling, Tinker Bell, and Captain Hook. Most of the story takes place in Neverland in 1904. Barrie also wrote novels such as Half Hours and multiple plays. Throughout Peter Pan, the reader is taught different life lessons while enjoying

INTRODUCTION The thyroid is Greek word for “shield shaped” from the shape of the nearby tracheal cartilage. The thyroid gland was named “glandulae thyroidaeae” by Wharton in 1656.[1] The thyroid gland is the source of two fundamentally different types of hormones, produced by thyroid follicles, idothyronine hormone thyroxine (T4) and 3, 5, 3’- triidotyronine (T3). Fig 1.1:- Conversion of T4 to T3 and Reverse T3. 1.1 Regulation of thyroid hormones in human body Thyroid hormones (T3 & T4) are essential

Meet your thyroid The thyroid gland controls how hard other parts of your body work by producing hormones (chemical messengers) that increase the energy burnt off by almost every tissue and organ.⁶ Hormones produced by the thyroid ensure that your heart pumps properly, that you can breathe and move, and that your liver and kidneys get rid of toxic waste. Thyroid hormones are essential for reproduction and to make sure your baby is healthy. Thyroid hormones help keep you looking well and attrac-

Growth hormone Growth hormone is a hormone that stimulates growth in the body. The growth hormone causes the bones to become longer. What is a growth hormone? Growth hormone controls the growth process and provides the right amounts of fat, water and muscle in the body. It stimulates the construction of new cells and the production of firm bone tissue. Growth hormone is also affecting concentricity and memory. The release of growth hormone Hormones are substances released by glands in the body. Hormones

The HGH weight loss program has many pros and cons when it comes to dieting and eating. Before jumping into how human growth hormones worked, We needed to figure out if one could easily burn fat and gain muscle with the right eating habits and enough routine exercise. We found the human growth hormones can come in an injection based for powered base form and also pill form. Human growth hormones have been tested to show that a few small studies have link human growth hormone injections with fat loss

MELANOTAN II PRODUCT DESCRIPTION Melanotan II is a lab synthesized peptide hormone that imitates melanocyte-stimulating hormone (a hormone that naturally occurs in the human body). Alpha-MSH (also referred to as α-MSH or alpha-melanocyte-stimulating hormone (MSHs) stimulates the melanogenesis; the process by which the skin and hair darkening pigments are produced in mammals. In vitro administration of Melanotan II has been observed to have excellent portent melanotropic action. The structural name

In the vast African Savanna, many people are sleeping at night in the middle of it all, cozy near a campfire. A twig breaks, and one of the men wake up, who later decides to go back to sleep. The sound comes again more frequently, which is when everyone has woken up. On the southern side, they see a moving animal just walking in circles around them. Everyone is afraid, but they do not know what it is… until is roars. The beast is a lion, and all of the men are sure they are going to die. This is

Goiter Throughout all of nursing school, we haven’t really talked about the endocrine system until now. I couldn’t even tell you what goiter is before I started writing this paper if that says anything. The endocrine system is very important in the human body and serious complications can occur if any part of the system is impaired. This paper will include the pathophysiology, etiology, causes, risk factors, complications, nursing care, interventions and current treatments associated with goiter

Question 1 - The Pathophysiology Explain the pathophysiology of Mr Jensen’s post-operative hypovolemia and how some of his post-operative assessment data might have contributed to this. In addition explain how the body might compensate for this physiologically (approximately 800 words). (997 Words) Mr George Jensen is a 65-year old male who was brought into Emergency Department with an open fracture of his right tibia and fibula after falling from his roof. Taken to theatre as an emergency case

The Endocrine system is important to maintain the balance between our bodies organs, organ systems and the body; the endocrine system controls hormone production and distribution of hormones (Lurie, n.d). Cancer of any of these glands can result in the cancer producing hormones that can interfere with normal body function (Lurie, n.d). Cancer is the uncontrollable growth of malignant cells. Endocrine cancer can happen on any of the organs of the system and is more likely to affect women (Dr. Jemal

PROBLEM AND ITS SCOPE INTRODUCTION The pancreas is a glandular organ in the upper abdomen, it is considered into two glands and have different of action, these are the endocrine and exocrine gland. In the endocrine part it is responsible for the production of hormones in the so-called islets of Langerhans. In the islets it contains endocrine cells which produce specific cells called an Alpha cell which is responsible for the release of the hormone glucagon, the Beta cells which releases insulin in response

Sympathetic and Parasympathetic Nervous System Salma Ewing Feb 15, 2018 The sympathetic and parasympathetic nervous system are two divisions of the autonomic nervous system of the body. They are very closely related and coordinated with each other and regulate the unconscious functions of the body. The autonomic nervous system is responsible for our involuntary reactions and controls our heart beat, digestive processes, blood flow and hormone production. This means that we can’t consciously control
