HORMONES Hormones are a class of regulatory biochemicals produced in all multicellular organisms by glands‚ and transported by the circulatory system to a distant target organ to coordinate its physiology and behavior. They serve as a major form of communication between different organs and tissues. Hormones regulate a variety of physiological and behavioral activities‚ including digestion‚ metabolism‚ respiration‚ tissue function‚ sensory perception‚ sleep‚excretion‚ lactation‚ stress‚ growth and

Hyperparathyroidism having too much parathyroid hormone in the bloodstream due to over excretion of the body’s parathyroid glands located in the neck. The parathyroid glands secrete parathyroid hormone‚ which helps maintain a correct balance of calcium in the bloodstream and in tissues that depend on calcium for proper functioning. There are two types of hyperparathyroidism‚ primary

Eric’s symptoms are hormonal‚ he is clearly having an endocrine gland problem. Cortisone‚ testosterone‚ and growth hormone levels are being affected‚ it is likely that he his having a hormonal problem within his anterior pituitary gland‚ because all three of these hormones are regulated by a horomone that this gland secretes. Cortisone is controlled by ACTH‚ testosterone by LH and FSH‚ and growth hormone by the anterior pituitary gland itself. Not to mention‚ the thyroid is regulated by the thyroid-stimulating

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

endocrine system is the second greatest control system of the body and has many effects on the tissues and organs. The thyroid gland‚ which is a part of the endocrine system‚ releases a hormone that maintains metabolism. This hormone is thyroxine. Thyroxine production is controlled by thyroid stimulating hormone‚ which is released by the pituitary gland. TSH stimulates the thyroid gland to produce thyroxine. In this experiment‚ the effects of TSH and thyoxine on metabolic rate are investigated. Hypothesis:

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
