Addison’s Disease‚ Adrenal gland dysfunction is typically related to a maladaption to stress‚ as first reported by Hans Selye in the general adaptation theory (GAS). [pic] The General Adaptation Syndrome (GAS) In order to develop a general theory for the physiological response of humans and animals to stress‚ Hans Selye‚ former director of Experimental Medicine and Surgery at the University of Montreal‚ performed an integrated analysis of the effects of stress on adrenal gland function. He called

strictly biological approach to treatment of these abnormalities may not be enough to overcome the adaptive organ systems of the human body. Technology limits scientists’ understanding of particular systems‚ especially in the case of the human endocrine system‚ and I think that many other models‚ particularly the humanistic-existential model‚ were theorized to speculate on biological processes or connections not yet explained by science. The resulting non-biological models act as contemporary‚

perspiration. Such physical effects are caused by Adrenaline. Adrenaline is a hormone that is released from a person’s adrenal medulla during emergency situations but does not have psychoactive effects. It is released into the person’s body from the adrenal glands located above the kidney. It is commonly referred to as a “fight-or-flight” hormone‚ because of its effects in increasing the supply of glucose and oxygen directed at a person’s brain and involuntary muscles. This allows the person to have better

Sjogren syndrome is a chronic‚ slowly progressive‚ inflammatory autoimmune disorder characterized by dryness of the mouth and eyes. This autoimmune illness features inflammation in the lacrimal and parotid glands. The inflammation in the lacrimal gland leads to decreased water production for tears‚ causing dry eyes. The inflammation in the parotid leads to decreased saliva production in the mouth‚ causing dry mouth and dry lips. The two distinct forms of Sjogren syndrome are primary and secondary

ACTH stimulates adrenal glands. Adrenal glands then release hormones (cortisol) including catecholamines‚ which increases the sympathetic nervous system and decrease parasympathetic activation.

TITLE PINEAL GLAND: “THE HIDDEN EYE” INTRODUCTION The third eye‚ also referred as parietal eye or pineal eye‚ is a photosensory organ that triggers hormone production and thermoregulation. This eye cannot see in quite the same way as the main eyes‚ instead only detecting shapes and shadows rather than full pictures. They are also highly sensitive to changes in light and dark – producing markedly different hormones based on time of day. It produces melatonin‚ a hormone that affects the modulation

The amygdala triggers hypothalamus to bring messages through sympathetic centers in the spinal cord which then get to the middle of the adrenal gland called adrenal medulla‚ and release hormone 2 called adrenalin (epinephrine) and norepinephrine (also known as noradrenaline) (Lightman‚ S. 2008). Adrenaline and noradrenalin are chemicals that released into the blood stream by nerve endings of the

Estrogen Chemicals can be found in: * Pharmaceuticals (hormone therapy drugs‚ birth control pills) * Pesticides (insecticides‚ fungicides) * Plastic linked products (Bisphenol A‚ phthalates) * Heavy metals (Mercury‚ Lead) * Household Products (detergents) Environmental Estrogens are manufactured for a purpose such as contraceptives and pesticides.

from the egg whites of a hen. After 1930‚ the bactericidal action of lysozyme was established and numerous studies conveyed that all living organisms produced lysozyme [1]. Tear lysozyme is a long chain glycolytic enzyme secreted by the lachrymal gland [3]. Lysozyme constitutes around twenty to forty percent of the total tear protein [3]. Its concentration in the tear is higher than in any other fluid of the body [1]. This protein has the ability to break down bacterial walls by the enzymatic digestion
