The main function of the pituitary gland is to regulate the human growth hormone (HGH) and weight; main controller along with the genes of final height of a person. A malfunction in the pituitary gland can cause hypersecretion which results in gigantism or acromegaly and hypo secretion can result in dwarfism. The Thyroid Gland: The Thyroid gland is a very small vascular organ that is located in the neck. It consists of two lobes, one on each side of the trachea, just below the larynx or the voice box. The two lobes are
Hormones regulate various human functions, including metabolism, growth and development, tissue function, sleep, and mood. The field of study dealing with the endocrine system and its disorders is endocrinology, a branch of internal medicine. Features of endocrine glands are, in general, their ductless nature, their vascularity, and usually the presence of intracellular vacuoles or granules storing their hormones. In contrast, exocrine glands, such as salivary glands, sweat glands, and glands within the gastrointestinal tract, tend to
Hypothalamus regulates the Pituitary Gland, by release of regulatory hormones -Negative feedback mechanism regulated How does the hypothalamus control the anterior pituitary? Hypothalamus produces Regulatory Hormones that are release by hypothalamic neurons into Portal Veins that descend into the Anterior Pituitary casueing it to either to release hormones or inhibit hormone release What is the hypophyseal portal system and why is it important? An extensive capillary network that surround endocrine cells of the Anterior Pituitary, provides an entry point into the blood stream for hormones secreted by the Anterior
3. Return to the main Endocrine System homepage and click on the Pituitary Gland. a. The pituitary produces several hormones that regulate various parts including other endocrine glands. This rather large role earns it the “master gland” nickname.
Endocrine glands have a rich blood supply through which hormones travel to reach their target organs. Hormones alter the metabolism of target organs by increasing or decreasing their activity. These changes in activity are strictly balanced to maintain homeostasis (a stable internal environment). Many endocrine glands are linked to neural control centers by homeostatic feedback mechanisms. The two types of feedback mechanisms are negative feedback and positive feedback.
Atropine acts as an antagonist within the central nervous system, which means it acts as a blocker of specific cellular functions. What part of the autonomic nervous system does atropine block to produce its effect on Dr. Westwood? Atropine was administered in response to the bradycardia; after it was administered it brought up his blood pressure as well has his heart rate. Within the parasympathetic nervous system, Atropine blocks the muscarinic receptor which then blocks acetylcholine (Ach). Because of the blockage of Ach the muscarinic receptor antagonist can block the vagal nerve from affecting the heart, and can then increase the heart
These glands produce hormones that regulate essential bodily functions; these glands are known as adrenal glands. 21-hydroxylase is an enzyme that creates cholesterol. Cholesterol is produces from two hormones, cortisol and aldosterone. Cortisol maintains blood sugar levels, protects the body from stress, and suppresses inflammation.
This means the metabolic system is essential for the body getting energy. Diabetes specifically affects the pancreas, and insulin production. Insulin regulate glucose, or sugar, in the blood. As a result, blood sugar levels are affected. Other than the digestive system, numerous body systems are affected, because blood sugar is essential to maintaining bodily functions.
Hormones are produced by the glands and a few organs spread in different places of the body. According to Morris and Maisto (2002) the glands engaged in hormone production are thyroid, parathyroids, pineal, pituitary, gonads, and adrenal glands. Pancreas and some parts of the digestive tract also play role in the production of certain hormones which working together with glands has an effect of many other areas of the human body. Genes are which give us different hereditary characteristics. They do have an effect on behavior; but, not single genes.
The thyroid also has a gland that is located at the base of the brain and controls how the thyroid works. It is called the pituitary gland and the two hormones that are produced are traveled down the bloodstream to the thyroid (Hormone). Hyperthyroidism is one of the most common diseases out of the thyroid diseases. Basically, too many of the hormone, thyroxine are produced and given to the thyroid from the pituitary gland. Hyperthyroidism speeds up the body’s metabolism which in turn makes the body have a significant weight loss, a weird heartbeat, sweating profusely, and nervousness.
