Hypothalamus:- A part of lover middle brain that control and the pituitary gland to release hormone. It influences part of brain that controls hormone production by releasing different chemicals to the pituitary gland.…
1. What were the main findings of Mr. Penzey’s physical exam? How could his CT results be related to his blood pressure findings? A physical examination for high blood pressure also comprises a medical history.…
The hypothalamus receives input regarding hunger and blood pressure from the vagus nerve; skin temperature from the brain stem; light and dark from the optic nerve; and ion balance and blood temperature from itself. When it receives this information, the hypothalamus sends hormones to different parts of the body depending on what is happening. For example, if something frightening is happening, the hypothalamus can communicate with the amygdala through the ventral amygdolafugal pathway, and trigger the ‘fight or flight’ response. The hypothalamus’ ability to control so many parts of the human body from so much information makes it a vital part of not only maintaining homeostasis, but in how we act on our…
I have chosen the area of OB/GYN to research and explore, more specifically the labor and delivery. I don’t have any experience when I comes to delivery children but I will take classes in the future that will help me with this. I have taken physical science, biology, parenting and I’m taking chemistry. Next semester I’m taking health science and next year I’m taking AP biology classes because I love helping people.…
1.) According to Jonbarron.org, an endocrine tumor is a mass that begins in the parts of the body that produce and release hormones. The neoplastic cells secrete the hormone normally produces by the cells of the gland, but they are not responding to negative feedback which controls mechanisms so hormones re secreted in an inappropriate and excessive manner. Because an endocrine tumor develops from cells that produce hormones, the tumor itself can produce hormones and cause serious illness. 2.)…
These sections of the nervous system are governed by the Neurones, they differ in their purpose, substantial support, and in administering substance signature, below is my attempt to pen down their…
The major role of the HPA axis is to mediate the neuroendocrine stress response, in order to reestablish body homeostasis after an acute stressor (4).A principal component of the stress response is the CRH system, which is located in the paraventricular nucleus (PVN) of the hypothalamus. CRH is synthesized by neurons in the parvocellular/small cell division of the PVN, and it is secreted into the pituitary portal blood (5-7). CRH via portal blood enters the anterior pituitary and binds to type 1 CRH cell-surface receptors, resulting in ACTH secretion (8-10). ACTH acts on the adrenal cortex, specifically on the zona fasciculata, to stimulate cortisol secretion (11). Cortisol inhibits the secretion of CRH and ACTH from the hypothalamus and anterior pituitary, respectively (11).…
Descriptive title:- Cortisol is an adrenal steroid hormone. According to S. Kalmijn, L. J. Lauren, R. P. Stalk, F. H. De Jong, H. A. P. Pols, A. Hofman, M. M. B. Breteler, and S. W. J. Lamberts, it has been presented that in animal studies, Cortisol has demonstrated to have numerous effects on the activity of the hippocampus, which is convoluted in Learning and memory development. ACTH is a 39 amino acid polypeptide predominantly synthesized in and Secreted from the anterior lobe of the pituitary gland. According to Yewie Xing, C Richard Parker, Michael Edwards and William E Rainey, ACTH subsequently activated adrenal cortex enlargement of corticosteroid Production (chiefly cortisol in humans).…
In the article, “ He stress, She Stress” by Susan Galdos talks about the difference between male and female stress levels and why. Men and women take in stress completely different. Throughout both lifetimes, females have a much higher risk of getting stress-related disorders than men. Stress disorders like PTSD and Major depression are twice as likely in females than in males. Since males and females have different sex hormones it causes a tremendous difference in how each sex deals with stress.…
Feedback mechanisms are important for maintaining the body’s homeostasis. First, a stimulus affects the environment. Then, a receptor detects the change and a responds accordingly. Input information travels to the control center. Once the control center deciphers how to solve the problem, output information is sent to the site where the effector is.…
Also known as the love or hug drug, Oxytocin serves as a neurotransmitter and hormone that plays a role in human tendency to feel pleasure and form emotional bonds with others. It is in the hypothalamus located in the brain which is then transported to the pituitary gland, which is located at the main base of the brain. The impact of the different oxytocin levels determines the outcome of the emotions and feelings. It also plays a role in sexual relations, before and after childbirth and bonding between people. For an example, a large amount of oxytocin is released when a mother has went into labor and given birth.…
Oxytocin is an extremely mysterious and useful hormone that is kept out of the eye of basic human knowledge. For instance, oxytocin is known as the cuddle hormone because it is released when you hug someone. This is the reason why people normally feel secure when we hug one another and why we thrive for human contact. The hormone not only enhances empathy but also fine tunes brain social instinct, strengthen close relationships, and makes you more willing to support people. Oxytocin does all these amazing abilities ,but its mystery still stands.…
Fetal Alcohol Syndrome Sandra Reynoso | MDCA 1409 | 09/19/2016 PAGE 1 Just one you might say. But did you know that just one alcoholic drink can permanently harm your unborn child. Your child might suffer from many birth defects like facial abnormalities, lower IQ, problems in their central nervous system among many others. All this can be prevented!…
Blood sugar regulation is the process by which the levels of blood sugar, primarily glucose, are maintained by the body within a narrow range. This phenomenon of tight regulation is commonly referred to as glucose homeostasis. Insulin and glucagon are the most well-known of the hormones involved. Blood sugar levels are regulated by negative feedback in order to keep the body in homeostasis. The levels of glucose in the blood are monitored by many tissues, but the cells in the pancreas's Islets of Langerhans are among the best understood and important.…
The Endocrine System is considered to be an integrative system because the hormones which are produced by this system act at the distance, many of those substances act in the different organs. The endocrine system and nervous system work together to coordinate functions of all systems in human body, they are responsible for maintaining the internal environment, nearly all physiological processes are affected by the hormones. They regulate almost all body function starting from metabolism, grow and development as well as water and electrolyte balance, reproduction and human behaviour. This system uses just one method of communication which are a chemical signals which are hormones, where the nervous system uses two: chemical and the electrical…
