The Endocrine System

It differentiates the role of gonadal hormones in both humans and non-humans, and asserts

Case Study 1 – The Endocrine System Christina D’Amico University of Saint Joseph Abstract A fifteen-year-old boy with many hormonal abnormalities starting at the age of eleven suffered from joint pain and swelling along with poor bone growth and development. He broke his left hip and had low levels of testosterone and high levels of growth hormone resulting in gigantism and later acromegaly.

What is Pitocin? Pitocin is the name brand of Oxytocin which is a drug used to help with contractions during labor. It is also a natural hormone found in the female body during the childbirth process that helps with contractions and induces labor. It is also used during miscarriages to contract the uterus to push the fetus into the birth canal.

1. What hormonal problem could be causing these symptoms Eric experienced from about age 11 to age 15? A pituitary tumor or malfunction could be the cause of all of the symptoms Eric was experiencing between the ages of 11 and 15. The pituitary gland is responsible for the secretion of Growth Hormone (GH), Thyroid Stimulating Hormone (TSH), Adrenocorticotropic Hormone (ACTH), and Luteinizing Hormone (LH) as well as other hormones.

Every one of us knows that testosterone is the quintessential male hormone. In the physical sense, it is what makes a man a man. The primary male hormone plays a major role in the development of male reproductive issues as well in in the such secondary sexual characteristics as body mass, muscle strength, and body hair. In puberty, it builds our muscles, deepens our voices, grows our beards, and increases the size of our penis and testes. Thank you very much!

An endocrine disruptor can block hormones and disrupt bodily functions. Some effects of disruption can include overproduction or underproduction of hormones, and blocking some effects of hormones from receptors. Some questions raised are: Did Dr. Hayes record inaccurate data due to his methodology and misrepresentations of other citations? Did Dr. Hayes’ data even support his conclusions? If Dr. Hayes’ believes his research is correct, why won’t he release his raw data for independent review?

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

Estrogen is a hormone that is shown in the human body. It can be found in three forms: estradiol, estrone and estriol. Ovarian tissue, and follicles of the ovary synthesize high levels of estrogen. Estradiol is one of the most understood sex steroids. Estradiol is a weaker estrogen.

They are the primary adrenal insufficiency and the secondary adrenal insufficiency. The primary adrenal insufficiency involves a major dysfunction in the adrenal cortex or the pituitary gland. The first type of Primary Adrenal Insufficiency only effects the adrenal glands and is known as Idiopathic Adrenal insufficiency. The second type known as Polyendocrine deficiency occurs when the adrenal cortex and pituitary gland are not producing the hormone ACTH that is vital to the creating of cortisol and the health and function of the adrenal glands. Cortisol is essential to the everyday life of any person and consequences of the lack of cortisol can be life threatening.

The human body is both complex in its function and fascinating in its capabilities. There are multiple hormones and proteins and many other things that are working together simultaneously to keep the human body working like a well-oiled machine. Anything that alters or hinders this process will result in the our body responding to the lost function by giving us few signs that will help us recognize where in the body is the problem and how can we fix it. Hormones controls our body’s day to day functions, such as our sleep, temperature, appetite, growth, weight and many more.

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.

The endocrine system is such an important system to the body because it functions the bodies use of hormones. The body uses many different hormones and the endocrine system regulates these. When the glands of the endocrine system secrete the hormones, the hormones are put into the bloodstream to be sent to the different parts of the body. The glands that comprise the endocrine system are the hypothalamus, the pituitary gland, and the pineal gland which are all located in the brain, the thyroid, parathyroid, and thymus which are located in the throat, the adrenals and pancreas which are located in the body’s midsection, and the ovaries (female) and testes (male) which are located in the pelvic region. The system is so important because it regulates the body’s metabolism, growth and sexual development, digestion, heart rate, and many of the other body functions regulated by hormones.

When blood glucose levels rise above 5mM, the release the hormone insulin to lower this. (glycogenesis) Insulin receptors are found in the liver, muscles and fat cells. Once the insulin hormone bonds to the insulin receptor it stimulates an increased intake of glucose into these tissues, lowering blood glucose levels. The glucose taken in by the liver is stored mostly as glycogen.

GnRH is responsible for the release of Luteinizing hormones and follicle-stimulating hormones by the pituitary, the suppression of testosterone, estrogens, and sexual
