Pituitary adenoma

Introduction In vertebrates, reproduction is primarily controlled by the hypothalamus-pituitary-gonad axis. The gonadotropin-releasing hormone (GnRH) neurons in the hypothalamus are key regulators of the hypothalamic neuroendocrine system mainly though the synthesis of GnRH (Moenter et al., 2003). The decapeptide GnRH is released from the hypothalamus in a pulsatile manner, and the amplitude and frequency of these pulses change throughout the estrous cycle (McCartney et al., 2002; Moenter et al.…

These glands are closely associated with the hypothalamus in their functionality. As such, the pituitary gland produces an array of hormones once it receives signals from the hypothalamus. These hormones are responsible for regulating the activities of the other glands, such as prolactin, which is involved in milk production, adrenocorticotropic hormone which responds to stress through a stimulation of the epinephrine, hormone responsible for the stimulation of thyroid, as well as the…

Which of the following hormones is correctly matched to its source and function(s)? A) melatonin: pituitary gland; controls mood B) thymosin: thyroid gland; regulates metabolism C) gastrin: kidney; controls blood pressure D) ANP: heart; regulates blood Ca2+ E) EPO: kidney; stimulates formation of red blood cells ____ 78. Which of the following is NOT correct…

The onset of syndrome can be triggered by prolonged use of medication such corticosteroids used for treatment of arthritis. Also, Cushing’s syndrome can be caused by tumor of pituitary or adrenal glands. The treatment would require the surgical intervention, the removal of tumor and possible long-termed use of medications in order to sustain normal function of removed glands. iii.) Positive feedback increases variable and boosting…

sleep, mood or sex drive. The pituitary gland is an endocrine gland that controls the other endocrine glands and has a major impact growth, metabolism and maturation. As well as that, the pituitary gland is about the size of a pea and is located at the base of the…

Mandy Roberson Endocrine System The endocrine system has to do with the hormones of the body. Hormones are chemical messengers that travel throughout the bloodstream to other tissues. These hormones are secreted by endocrine glands throughout the body. Hormones help with the functions of certain organs and glands and help with digestion, muscle contraction, sex hormones for reproduction, sleep, and much more. They can really dictate how chemicals in the body react. The major function of the…

The endocrine system is the collection of glands that produce hormones, which regulate metabolism, growth & development, sexual function, reproduction, sleep & mood, and tissue function. The endocrine system is made up of the pituitary gland, thryroid gland, parathyroid glands, adrenal glands, pancreas, ovaries, and testicles. (Frucht, 2012 p.315). A gland selects and removes materials from the blood, hormones then travel through the blood to target organs to adjust their activity. This system…

produce up to 2 secretions (Hormones) but mostly each gland will have the task of producing one. These glands are ductless, which is why they secrete directly into the blood. This is a list of the glands which are a part of this system; Pineal, Pituitary, thyroid, parathyroid, adrenal and parts of the pancreas, ovaries and testes. Digestive system - The digestion system has two parts to it, the alimentary canal and the accessory organs. The canal is basically starting at the mouth and ending…

It is now well established that the brain and the gut are engaged in constant bi-directional communication. Most individuals are made aware of such communication when alteration in gastrointestinal function is communicated to the brain bringing about the perception of visceral events such as nausea, satiety, and pain or when, in turn, stressful experiences lead to altered gastrointestinal secretions and motility. The mechanisms which allow communication between the central nervous system (CNS)…

The pituitary gland produces several important hormones that control body functions such as growth, development, reproduction, and metabolism. One of these hormones is growth Hormone (GH). In childhood, GH is important for proper development and growth. In adults GH maintains healthy bone and muscle function. If there is not enough growth hormone, a child will not grow to his potential stature. If there is too much growth hormone a child will grow excessively tall. If there is an excess of…
