cancer lesions” (88). Blue light is a natural signal to the brain that it is daytime; therefore, it is time to be awake and productive in society. However, Ford also warns that the amount of blue light exposure can be detrimental to health because it affects the production of melatonin in the brain. Barone states, “People normally produce melatonin in the evening starting a few hours before bed as part of our natural circadian rhythm” (10). Melatonin is a sleep-inducing hormone produced by the pineal gland in the brain. When secretion is inhibited by the body -- because it still thinks it’s daytime with the excessive blue light emittance -- the natural sleep cycle is disrupted (Komada et al 320). The natural sleep cycle, or circadian rhythm, is defined as “the biological clock that keeps us in sync with this daily cycle” (Barone 10). It allows the body to respond to daylight in order to differentiate between night and day (Barone 10). Ford mentions, “Melatonin is secreted by the pineal gland in the presence of darkness” (88). Therefore, with the increased light at night and right before bed people are not receiving good sleep because their brains are not producing as much melatonin due to increased blue light emittance. Likewise, “Blue light exposure at night has been shown to affect the quality of sleep” (Ford 88). This suppressed melatonin production could have serious consequences: it could cause developing tumors that can cause cancers (Ford 90). The short-wavelength…

Lying within the core of the human brain is a small gland known as the pineal gland which is the principal conductor and regulator of the endocrine system. Furthermore, another essential process that the pineal gland undergoes is the secretion of melatonin, an autacoid hormone that controls the body’s circadian rhythm. Aside from controlling the body’s natural circadian rhythm, melatonin is used to cure many different conditions including radiation exposure, Alzheimer’s disease, and tinnitus.…

Outline Introduce the problem 1-2 sentences 50 words Decades have passed and the science community researched and were still not able to discover the biological function of the pituitary gland that was said to be the " seat of the soul". Philosophers have claimed that the pituitary gland is the habitat of the soul Before criticizing the claim, articulate it clearly so that we understand why someone would make each a claim. In other words, present the argument of your opponent in debate,…

What is the endocrine system and how does it function? Name 6 major endocrine glands and explain their functions. Endocrine is made of glands that create and discharge hormones, letting chemical substance keep actives the cells or organs. 1.Adrenal glands: helps to control the blood sugar. 2.Hypothalamus: Is in control of pituitary hormones by liberating others type of hormones. 3.Ovaries: it found in women and have the fiction to produce estrogen and progesterone.Also, is the responsible of…

I Blame the Hormones By: Taylor Aubin Organs and tissues that make up the endocrine system are the hypothalamus, pituitary gland, thyroid gland, thymus, suprarenal glands, pineal gland, parathyroid glands, heart, kidneys, adipose tissue, digestive tract, pancreas, and gonads. The effects of the endocrine system are vast and impact almost every organ and cell of the body. This system produces hormones that help maintain homeostasis through the regulation of metabolism, growth, tissue function,…

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…

secreting glands located throughout the palate, nasal and oral cavity. Salivary gland cancer is uncommon. Also, it is about 2% of head and neck tumors forming in the salivary glands, the majority in the parotid. The range incidence happen in the year bout 0.4 to 13.5 cases per 100,000. [14]. can distinguish this disease through know some symptoms such as pain,fluid ,draining from the ear, numbness, weakness,a lump, and trouble swallowing the most type of salivary gland cancer when gland has a…

levels of glucose, the humoral stimuli would trigger a hormone release from the pancreas known as insulin. Insulin’s job would be to bring the blood glucose levels back down. • The main function of hormonal stimuli is to release hormones whenever stimulated by other hormones from the endocrine system, such as the hypothalamus. For example, the hypothalamus and the pituitary gland are known…

The release of hormones throughout the human body impacts society daily. By definition, hormones are chemicals that are released by glands which circulate in the bloodstream and act as messengers affecting particular cells and organs. With this, hormones affect human behavior. According to emedicinehealth.com, the endocrine system is made up of glands that produce and secrete hormones, chemical substances produced in the body that regulate the activity of cells or organs. This system enables…

Endocrine System The endocrine system is basically the network of glands that secrete hormones into the blood stream which regulates activities of cells or organs. The sexual development and function of the body and the metabolism are two examples of what the endocrine systems does. The major contributors to the endocrine system include the pituitary gland, thyroid, hypothalamus, parathyroid, adrenal glands, pineal body, reproductive glands, and the pancreas. The pituitary gland is…
