You have a pituitory gland. It produces many hormones including growth hormone.
It's the master gland that secreat all the homones
HGH is the "master hormone" controlling many organs and body functions and is directly responsible for stimulating tissue repair, cell replacement, brain functions, and enzyme function! It's human growth hormone that grows the cells, bones, muscles, and organs, and it is the decreasing level of human growth hormone after age 30 that slowly robs us of our "youth."
The pituitary gland is a pea-sized organ located in the brain, and secretes MANY different hormones that control growth and functioning of tissues and other glands in the body. The pituitary gland secretes: Thyroid stimulating hormone (TSH), follicle stimulating hormone (FSH), luteinizing hormone (LH), adrenocorticotropic hormone (ACTH), prolactin (PRL), growth hormone (GH), as well as oxytocin and antidiuretic hormone (ADH).
Pituitary gland that is also known as a master gland of endocrine system secrets and stores growth hormone. The thyroid gland helps with growth and development.
The Growth Hormone (GH). This hormone is produced by the Petuitary Gland (The master gland)
The anterior pituitary synthesizes and secretes the following important endocrine hormones: Adrenocorticotropic hormone (ACTH), release under influence of hypothalamic Corticotropin Releasing Hormone (CRH). Thyroid-stimulating hormone (TSH), release under influence of hypothalamic Thyrotropin Releasing Hormone (TRH). Growth hormone (also referred to as 'Human Growth Hormone', 'HGH' or 'GH' or somatotropin), release under influence of hypothalamic Growth Hormone Releasing Hormone (GHRH); inhibited by hypothalamic Somatostatin. Prolactin (PRL), also known as 'Luteotropic' hormone (LTH), release under influence of multiple hypothalamic Prolactin Releasing Factors (PRH). The two 'Gonadotropins'; Luteinizing hormone (also referred to as 'Lutropin' or 'LH', or in males, 'Interstitial Cell Stimulating Hormone' (ICSH)), and Follicle stimulating hormone (FSH), both released under influence of Gonadotropin Releasing Hormone (GnRH). and; melanocyte-stimulating hormones (MSH's) or "intermedins" as these are released by the pars intermedia which is "the middle part"; adjacent to the posterior pituitary lobe, pars intermedia is a specific part developed from the anterior pituitary lobe. The posterior pituitary stores and releases: Oxytocin, most of which is released from the paraventricular nucleus in the hypothalamus Antidiuretic hormone (ADH, also known as vasopressin and AVP, arginine vasopressin), the majority of which is released from the supraoptic nucleus in the hypothalamus
Your pituitary is the master hormone gland which controls too many vital functions of your body apart. It secretes the growth hormone also.
Decreased secretion of the master gland, the pituitary gland, can lead to hormone imbalances and a variety of issues, such as growth problems, thyroid dysfunction, adrenal insufficiency, and reproductive disorders. Treatment may involve hormone replacement therapy to restore normal hormone levels.
thyroid hormone release is stimulated by thyroid stimulating hormone,which is released by adenohypophysis of pituitary gland .this in turn stimulated by thyroid releasing factor which is released by hypothalamus .in the presence of this thyroid stimulating hormone conversion of inactive iodine to active iodine takes place.and also formation of T3 and T4 hormones occurs under the influence of this hormone only, this reaction is favored by this hormone.it stimulates thyroid gland to release thyroid hormone which is composed of T3 and T4 units.T is nothing but the tyrosine units present in throglobulin a colloid present in lumen of thyroid follicles.
There are four: Follicle-stimulating hormone (FSH) Luteinizing hormone (LH) Adrenocorticotropic hormone (ACTH) Thyroid-stimulating hormone (TSH) They are in the Anterior Pituitary
The pituitary gland which is located at the base of the brain;sometimes called the master gland ;of the endocrine system.It is no larger than a pea;but does great work.It's main thing is to stimulate horomes in parts of the body.ACTH-stimulates the adrenal gland,TSH-thyroid glan,FSH-the ovaries and the testes.Melanocyte-to control skin color and pigmentation.antiduretic-to control water absorption into the blood and kidneys.Oxyytocin to contract the uterus at chid birth and stimulate milk production,But i was unable to find anything about polpeptides in the pituitary gland.
Wikipedia: "In biology, permissiveness is a certain relationship between hormones and the target cell. It can be applied to describe situations in which the presence of one hormone, at a certain concentration, is required in order to allow a second hormone to fully affect the target cell. For example, thyroid hormone increases the number of receptors available for epinephrine at the latter's target cell, thereby increasing epinephrine's effect at that cell. Without the thyroid hormone, epinephrine would have only a weak effect"
