Understanding Acromegaly: Symptoms, Diagnosis and Treatments Acromegaly is most commonly seen in adults who have a pituitary adenoma. This adenoma produces excess amounts of Growth Hormone (GH) which affects cartilaginous tissues such as the joints in hands and jaws, as well as the tissue of the nose, ears and heart. Because this growth is occurring after the epiphyseal plates have closed it creates a disproportionate appearance which is typically the first sign in the patient. There are several
Acromegaly is a pituitary gland disorder that is an unusual and rare disease that comes from the hypersecretion of growth hormone during adulthood. It is rare in that acromegaly occurs in about 5 cases per million per year (Lugo 2011). Acromegaly if often labeled as a prolonged metabolic condition that is characterized by steady enlargement or elongation of facial bones and extremities (Thibodeau, 2013). This paper will explain the disease and how it affects the body, how one who has the disease
Our Stolen Future is a book published in 1996, written by Theo Colborn that details the impact that atmospheric and ocean carried chemical containments have on the development and growth of organisms. This book completely changed the manner in which scientist approach the way in which they determine the impact to the environment due to chemical contamination. According to Our Stolen Future, the endocrine disruption hypothesis states that exogenous or synthetic chemicals can alter hormonal signals
Gigantism is a rare disease that seems to cause extreme growth of a person’s height, bones, muscles, and organs. It occurs when there is too much activity in the pituitary gland, creating a tumor. The tumor is typically large and it invades the brain tissue. Gigantism normally begins during early childhood and before a child’s bone growth plate closes. This disease is not very common and has only appeared in about 100 people throughout United States history. There are numerous symptoms to having
Diseases Of The Pituitary Gland The pituitary gland is a tiny organ the size of a pea located at the base of the brain. Despite its size, it is generally regarded as the master gland of the body, because it produces many hormones that travel throughout the body, as it directs certain processes and/or stimulates other hormones producing glands as well. The pituitary gland also stores many different hormones such as; Prolactin, which stimulates breast milk production after childbirth, and it affects
Endocrinology: The Role of Hormones in the Body. Endocrinology can be defined as the study of the structure and function of the endocrine system (Tortora & Grabowski 1996). The endocrine system is composed cells, known as endocrine cells, which are distributed around the body and produce the chemical messengers known as hormones. Following secretion by endocrine cells, hormones travel in the blood where they affect tissues outside of their tissue of origin - and are therefore a form of cellular
glands, and sebaceous glands, secrete chemical substances through ducts into an open space. (Constanti et al. 1998; Wilson et al. 1998) Hormones: Hormones are molecules that are produced by endocrine glands, including the hypothalamus, pituitary gland, adrenal glands, gonads, (i.e., testes and ovaries), thyroid gland, parathyroid glands, and pancreas. The term “endocrine” implies that in response to specific stimuli, the products of those glands are
The hypothalamus is a vital, small section of the brain that links between the endocrine and nervous systems. It links these two systems via the pituitary gland, a pea-sized gland that protrudes off of the bottom of the hypothalamus section of the brain. The hypothalamus is primarily responsible for hormone production and maintaining the body’s internal balance, also known as homeostasis. Homeostasis is responsible for regulating body temperature, body weight, electrolyte and fluid balance, and
What is a stressor? There can be many different definitions of stressor, but the type that occurs in the stress response is physiological. Taking this into consideration, a stressor is anything that causes a person stress either physically or psychologically. It is something that is either inflicted on us by an outside force or something that we perceive in our mind. Stressors can take the form of an outside agent, an event, or an environmental condition. Anything in a person’s day to day life may
a network of glands that work together to produce hormones and here is am example of some that may be small or have a small role in the endocrine system but are extremely important. The glands of the endocrine system are: hypothalamus, pineal, pituitary, thyroid, parathyroid, pancreas, adrenal, thymus and the female glands ovaries and the male glands the testes. These glands all produce different kinds of hormones in our bodies and they all do specific things that creates a response from, tissues
sexual development and purpose of restriction. The hormones are transmitted into the circulatory system and may influence maybe a couple or three organs all through the body. The fundamental glands of the endocrine system are the hypothalamus, pituitary, thyroid, parathyroids, adrenals, pineal body, and the regenerative organs (ovaries and balls). The pancreas is other than a touch of this system; it has a region
Acromegaly syndrome is caused by excess production of growth hormone by the pituitary gland after epiphyseal plate closure. Jay Cutler, the Chicago Bear NFL quarterback in 2008 developed type 1 diabetes -chronic condition in which the pancreas produces little or no insulin, needed to allow glucose to enter cells to produce energy
Oxytocin is a hormone, predominately belonging to mammalian family; it is secreted by the posterior pituitary gland. After its release in the blood stream it cannot re-enter the brain due to the presence of blood brain barrier .Oxytocin is a hormone that has both peripheral and central actions (32). They are synthesized in the magnocellular neurons present in the supra–optic and Para –ventricular nucleus present in the hypothalamus. The universally known functions would include its role at the time
system makes a fast response through specific glands and muscles. While the endocrine system is more widespread it also works at a slower pace. 2. A tropic hormone are hormones that target other glands and are mostly secreted in the anterior pituitary. One example of a tropic hormone involves the Thyroid-stimulating hormone (TSH) stimulates the thyroid
Your exams are coming up, although you’ve prepared all you can, when sitting down at the desk your heart is pumping at an abnormal pace and you may be breathing heavily or sweating. This is called Stress; everyone in this room has gone through stress sometime in their life. But I believe that stress can also be your friend. Let’s begin with the original point that established a new approach to stress for me on a personal level. There was a study released in 2008 by Harvard University, which trailed
The Pituitary gland has many functions and regulations that are continuously functioning.However when there is a disruption in those functions there is an imbalance. Prolactinoma is an imbalance caused by a non cancerous tumor. The tumor causes the secretion of prolactin.Prolactin in a type of hormone in which normally stimulates lactation. In turn the body reacts to this hormone prolactin in more than one way. The location of the pituitary gland is in the sella turcica of the sphenoid bone and
A. Hazrat Inayat Khan – a northern Indian classic singer- once said, “A person does not hear sound only through the ears; He hears sounds through every pore of his body, It permeates the entire being … In that way the physical body recuperates and becomes charged with new magnetism” (Mannes 167). B. Our bodies may not become literally magnetic upon listening to music but something does happen. Whether we’re driving home and have our radio on at the highest level, have Spotify on when showering, or
effects to human life. For instance, gigantism which is an abnormal growth caused by the excess hormone growth at childhood before the bone plates closes. Though gigantism is rare, it is caused due to some factors among them; Noncancerous tumor of the pituitary gland, Neurofibromatosis, McCune-Albright Syndrome (MAS), Carney complex and Multiple Endocrine Neoplasia type 1(MEN-1). This abnormal growth occurs mainly before the closure of the bone growth plate. In any case the growth hormone occurs after the
composed of two layers; the outer portion is the adrenal cortex and the inner region is the adrenal medulla. The adrenal cortex is signaled to secrete corticosteroids in response to the hormone, adrenocorticotrohpic hormone (ACTH), released by the pituitary gland, which is first signaled by corticotropin-releasing hormone (CTH) originating in the hypothalamus. In view of this pathway, Cushing’s syndrome may be the result of dysfunction in several areas of the body. There are several different causes
Abstract: This research paper focuses on the subspecialty of Neuro-ophthalmology and address the different disorders that are treated by an Neuro-ophthalmologist. what makes neuro-ophthalmology unique to all other sub-specialties, and how this contributes to making neuro-ophthalmology not only one of the most medically interesting, yet rewarding sub-specialties in ophthalmology. Ophthalmology is about saving the vision, but neuro-ophthalmology is sometimes also about saving lives. Isn’t that why
