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
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
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
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
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
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
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
In 1896 the scientist Beatson reported that the removal of the ovaries resulted in the reduction of breast cancer tumours (Russo and Irma 1998). Breast cancer is a malignant, metastasizing cancer of the mammary gland. It is the leading cause of death in woman between the ages of 35 - 45. Breast cancer can also occur in males, although less frequent, around 400 men die each year from breast cancer in the united states. (Martini, F., 2004). Studies on rats have shown
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
group of glands that create hormones in our bodies which help regulate growth and development, metabolism, sleep and mood as well as many others. The endocrine system secretes hormones internally through our blood stream. The endocrine system has 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
tissues, such as salivary 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
endocrine system is contained glands that pass on and discharge hormones, made substances made in the body that control the progression of cells or organs. These hormones encourage the body's change, assimilation (the physical and compound approaches of the body), and 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
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. Cutler
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
1. The general function of the endocrine system is gland based to produce hormones that help with metabolism, growth, tissues, and reproduction. The structure between the nervous system and endocrine system are very similar the basics of both systems involve triggering glands throughout the body from receptors. The function on the other hand is a little different because the nervous system makes a fast response through specific glands and muscles. While the endocrine system is more widespread
music 1. Impact on hormones a. To understand the relation of music to hormones, it is important to understand what hormones are. According to James Kalat’s 1998 book, “Biological Psychology”, hormones are a chemical that is secreted in most cases by a gland in our body and conveyed by the blood to other organs, whose activity it influences. Hormones serve as chemical messengers in our body that help with processes such as growth, and metabolism (Kalat 65). b. Our body continuously releases hormones in
fatty acids composed the plasma membrane. Steroid hormones are testosterone, estrogen and cortisol. Testosterone and estrogen are important regulators of reproductive function, secreted by the testes and the ovaries. Cortisol released by the adrenal gland due to stress and lowered levels of blood glucocorticoids is involved in stimulating glucose synthesis, anti-stress and anti-inflammatory processes. They can pass through the plasma membrane because they are lipid
the base of the brain just ventral to the thalamus. It has widespread connections with the rest of the forebrain and the midbrain. Partly through nerves and partly through hypothalamic hormones, the hypothalamus conveys messages to the pituitary gland, altering its release of hormones (Kalat, 2003). Any type of damage to a hypothalamic nucleus, such as tumors or lesions, may lead to abnormalities in one or more motivated behaviors, such as feeding, drinking, temperature regulation, sexual
endocrine system is a collaboration of all the glands in the human body and all the hormones produced by those glands1. The glands are controlled by the stimulation of the human nervous system including the chemical receptors in the blood and the hormones produced by other glands. By regulating and controlling the hormone levels in the body the endocrine system controls homeostasis in the body1. The gland system can be divided into two types. Exocrine glands release secretions outside of the bloodstream
Adrenal Glands Identification and description of organs which make up the endocrine system The human body comprises of organ systems which distinct but work together as a coordinated single unit (Marieb & Hoehn 1-35). This paper will single out the endocrine system because discussing the organ system in entirety is beyond the scope of this assignment. The adrenaline glands form part and parcel of the endocrine system, thus, the relevance of the topic. The endocrine glands comprise glands which secrete
