Luteinizing hormone is created by the pituitary gland and it is very important in the reproductive process as it allows ovulation to take place‚ alongside follicle stimulating hormones. The intermediate pineal is responsible for the production of melatonin which is considered to regulate the biological clock in humans‚ as it helps the brain to synchronise to daylight. The parathyroid gland is an extension of the thyroid gland‚ though this produced a separate hormone named parathormone

In vertebrates‚ the hypothalamus‚ located at the base if the brain‚ plays a central role in integrating the endocrine and nervous systems. The hypothalamus receives information from nerves throughout the body and the brain. (Mousa and Mousa‚ 2003) In response‚ the hypothalamus initiates endocrine signalling appropriate to environmental conditions. In many vertebrates’ nerve signals from the brain pass information to the hypothalamus about seasonal changes‚ therefore the hypothalamus regulates the

There are many various conditions and diseases affecting the endocrine system. Here we will discuss several and describe the endocrine gland‚ hormone‚ target tissue‚ symptoms‚ causes‚ and treatment options. The human chorionic gonadotropin (hCG) test is done to check for the hormone hCG in blood or urine (Staff‚ 2012). The hCG hormone is made during pregnancy by the placenta or can be abnormally made by certain tumors. The hCG test can be performed to test if a woman is pregnant or not‚ as part

ever heard this or something like these? People say this when people are not acting “normal”. You can’t control your hormones no matter what people think. A hormone‚ according to Randy J. Nelson(2017)‚ is a “chemical messengers released from endocrine glands that travel through the blood system to influence the nervous system to regulate behaviors such as aggression‚ mating‚ and parenting of individuals.” In Romeo and Juliet many of the characters were overly aggressive and lustful. Hormones effect

The thyroid gland is the gland that makes and stores hormones that help regulate the heart rate‚ blood pressure‚ body temperature‚ and metabolism. Thyroid hormones are essential for the function of every cell in the body. They help regulate growth and the rate of chemical reactions in the body. Thyroid hormones also help children grow and develop. The thyroid gland is located in the lower part of the neck‚ below the Adam’s apple‚ wrapped around the trachea. It has the shape of a butterfly with two

of 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

Cortisol is produced excessively. The excessive production of cortisol occurs when there is a benign (non-cancerous) tumor is formed at the anterior of the pituitary gland. This leads to the secretion of Adrenocorticotrophic Hormone (ACTH). ACTH is normally produced by the pituitary gland‚ and causes the stimulation of the adrenal glands resulting in the production of cortisol also known as the stress hormone (http://pituitary.ucla.edu/cushings-disease).

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
