Anterior pituitary

All living organisms, including humans, reproduce to ensure the survival of their species. The male and female reproductive systems are essential for reproduction. The main purpose of the male reproductive system is to produce and deliver sperm into the female reproductive system. The main purpose of the female reproductive system is to produce egg cells and to nurture a fertilized egg so it is able to develop into a fetus. The male and female reproductive systems are distinct from one another…

are caused by consuming alcohol. The high water temperatures can elevate the body temperature of the internal organs beyond safe limits. To maintain the body homeostasis, the thermoregulation mechanism which controlled by the hypothalamus and anterior pituitary gland could join in to lower the body temperature by opening the sweat glands or increasing the heat exchange. The opening of the sweat gland causes the water to lose more. In conclusion, Mr. Underhill weighted more than Mrs. Underhill,…

mediator molecules that are released into certain part of the body to control the cells in that part of the body, most of the hormones are secreted into the interstitial fluid surrounding the secretory cells. The endocrine glands consist of the pituitary, thyroid, parathyroid, adrenal and pineal glands. There are also glands that are not exclusively classified as endocrine glands these are the hypothalamus, thymus, pancreas, ovaries, testes, kidneys, stomach, liver, small intestine, skin, heart,…

then it is termed as Primary Hypogonadism. This is caused by chemotherapy or infection and characterized by elevated Luteinizing Hormone. If any disorders like tumors, genital or congenital conditions distract normal functioning of hypothalamic pituitary axis then Secondary Hypogonadism occurs in men. This complication is characterized by lower than normal level of Luteinizing Hormone. Diabetes- Low testosterone level and type-2 diabetes frequently go hand in hand. Studies reveal that men…

The paraventricular nucleus (PVN) in the hypothalamus contains parvocellular neurons synthesizes corticotropin-releasing hormone (CRH) and arginine vasopressin (AVP) which will stimulate the anterior pituitary to synthesize and release adrenocorticotropin hormone (ACTH) (Plotsky et al., 1993). Adrenocorticotropin hormones will stimulate the adrenal cortex to secrete cortisol. Charmandari et al (2003), states the over excess of glucocorticoids can…

in order to lower the hairs on the skin whereby air becomes circulated over and across the skin, stimulating more convection, evaporation and radiation. After sweat is lost, the receptors will send signals of thirst to the hypothalamus and to the pituitary gland, where it produces anti-diuretic hormone (ADH) which decreases urine volume (Kenney, n.d.). The body temperature then decreases to a steady state which causes the thermostat to shut off its cooling…

requires more of the balance, the ‘see-saw’ to allow the body to function better. If there is no balance, the body will begin to rot internally, and this is dangerous to the individual’s health. Faci, I have a few questions to ask you: 1. In the pituitary gland, the number of hormones released is based on the stimulus. Like is more water is taken into the body, less ADH is released. Does this apply to hypothalamus as well? If there is more water taken into the body, more releasing…

even deeper level they decipher the thought process behind those actions and inactions humans do. There are four different areas that control our brains and the way we think about brains. The four regions are the Amygdala Prefrontal cortex (PFC), Anterior cingulate cortex (ACC) and the Hippocampus. The impulses and signals sent throughout the…

46). “Thyrotoxicosis, known as the overproduction of thyroid hormones, could be caused by radiation exposure, ingestion of excess thyroid hormone, thyroiditis, interferon-alpha therapy, pituitary tumors, and metastatic thyroid cancer” (Crawford & Harris, 2012, p. 46). “Graves disease is an autoimmune disease characterized by abnormal stimulation of the thyroid gland, which makes antibodies that bind to the TSH receptor sites in the thyroid…

happen between 40 and 60 years old, also women are more likely to develop hyperthyroidism. Japanese people are at higher risk to develop the disease due to the high diet consumption of the saltwater fish rich in iodine. Consequently, Pain in the anterior neck will generally lead to a consideration of the risk of hyperthyroidism. Excessive sweating, anxiety, nervousness, palpitations, enlarged thyroid gland due to swollen appearance of the neck, eating well but losing weight, muscles weakness,…
