Recommended: What causes hypothyroidism essay

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 attaches to the hypothalamus(Marieb & Hoehn 441). The Hypothalamus is included in the function of the pituitary gland as it sends chemical stimulus to it(Marieb & Hoehn 442).Part of the pituitary is called the “ master endocrine gland” due to the fact that is produces many hormones that affect the whole body(Shannon 175).This part of the pituitary gland is called the anterior pituitary(Marieb & Hoehn 601). There are six hormones that the anterior pituitary secretes normally. These Hormones are growth hormones,thyroid stimulating hormones,adrenocorticotropic hormones,luteinizing hormones,follicle stimulating hormones and prolactin hormones( Shannon 175).The Hormone prolactin is one that in normal function stimulates the act of lactation for new mothers to feed their baby(Shannon 175).
The prolactin hormone is produced by the prolactin cells which are protein cells, primarily by the inhibitory hormone dopamine(Marieb & Hoehn 603).The hypothalamus is triggered from the increase of dopamine(Marieb & Hoehn 606).The levels of prolactin released depends on the amount of estrogen in the blood a woman has(Shannon 176).The secretion of prolactin normally happens when a woman is pregnant and after giving birth( Shannon 176). The estrogen when a...

  • Cushing’s Syndrome

    942 Words  | 2 Pages

    Cushing’s syndrome is defined as the hypersecretion of a class of steroid hormones known as corticosteroids such as cortisol. These substances, which are involved in anti-inflammatory and metabolic activities, are secreted by the cortex of the adrenal glands. The two triangle-shaped, suprarenal glands are 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.

  • The Common Functions of Oxytocin

    1388 Words  | 3 Pages

    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 of labour and ejection of milk. The functions which remain partially unknown are in erectile responses, ejaculation, bonding, and feeling of love and maintaince of eye contact during a conversation. This review is aimed at bringing into nutshell the common functions, defiency states and the commercially available forms of the same.

  • Hypothalamus: Regulatory Hormones

    There are five hypothalamic hormones that stimulate the anterior pituitary and are called tropic hormones. The first is called Thyrotropin-releasing Hormone (TRH) which increases the secretion of thyroid-stimulating hormone (TSH) and stimulates the release of thyroid hormone from the thyroid gland. The second is Prolactin-releasing hormone (PRH) which increases the secretion of prolactin (PRL) and primarily regulates breast milk in women. Gonadotropin-releasing hormone (GnRH) is the third and it increases the secretion of the follicle-stimulating hormone (FSH) and luteinizing hormone (LH) which regulates the production and maturation of sperm and oocytes as well as hormonal synthesis by the gonads. The fourth hormone is called Corticotropin-releasing hormone (CRH) which increases the secretion of adrenocorticotropic hormone (ACTH) that stimulates the adrenal cortex to produce and secrete corticosteroid hormones. An example of a corticosteroid hormone is cortisol. Lastly, the fifth hormone is the Growth hormone-releasing hormone (GHRH) which increases the secretion of growth hormone (GH) that stimulates cell growth throughout the

    Prolactin is a hormone (released by the anterior pituitary gland) that is most commonly known and named for its ability to stimulate lactation in female mammals, but additionally, serves several homeostatic functions and its involvement has been recorded in 300 biological processes (Freeman et. al 2000). Immune responses are enhanced by elevated levels of prolactin and even behavioral effect. For example, expression in rats has demonstrated parental behavior, such as nest building. Additionally, it is important to consider the vital function prolactin orthologues play

    Gonadotrophins are hormones that play a role in targeting certain structures in the Reproduction system. In females, they affect the ovaries and are produced during the menstrual cycle by the pituitary gland stimulation. There are two classes of gonadotrophins; follicle stimulating hormone (FSH) and luteinizing hormone (LH). FSH targets the follicles in the ovaries, preparing them for growth and development. LH’s primary function is to aide in the maturation of eggs, prior to ovulation. ?

    Disorders of thyroid hormone levels are one of the more commonly seen endocrine issues is patients.1 Thyroid hormones are synthesized in the thyroid gland and are then released at a rate of about 80 micrograms of T4, and 4 micrograms of T3 daily. Thyroid stimulating hormone (TSH), which is released from the anterior pituitary, is responsible for stimulating the release of thyroid hormones. In normal patients negative feedback of TSH would occur when the thyroid hormone blood levels were sufficient.

    This Paper will focus on the importance of the hypothalamus in endocrinology. The approach that will be taken is first examining the role of the hypothalamus in the endocrine system. We will then look at how the hypothalamus is able to carry out this role, which means focusing on the hormones it release. The following hormones will be observed: Thyrotrophic-releasing hormone, Growth hormone-releasing hormone, Corticotrophin-releasing hormone, and Gonadotropin-releasing hormone. Knowing the overall role each of these hormones will make more sense of the functions of the hypothalamus.

    The Endocrine System is made up of glands that make hormones that regulate metabolism, growth and development, tissue function, sexual function, reproduction, sleep, and mood. The glands that are in the Endocrine system are the Hypothalamus, Pineal Gland, Pituitary Gland, Thyroid, Parathyroid, Thymus, Adrenal, the Pancreas, Ovaries, and Testes. There are also many diseases that affect this system. For example, Prediabetes, Type 1 Diabetes, Type 2 Diabetes, and Osteoporosis. The Hypothalamus is part of the brain that has a certain number of small nuclei with a variety of functions. One of the most important functions of the Hypothalamus is that it links the Nervous System and the Endocrine System because of the Pituitary Gland. It also has the

According to the “Human Anatomy & Physiology” tenth edition by Elain N. Marieb and Katja Hoehn, glands in the human body are classified into two categories; they are endocrine glands and exocrine gland (Marieb & Hoehn, 2016). The endocrine glands are known as ductless glands because they lose their connection (duct) with the surface area as they develop. Thus, hormones they released go directly into the blood or lymphatic vessels
