Hypothalamus

MTSU has Starbucks right in the library where students go to study this is an addiction waiting to happen. According to Hershner and Chervin, “caffeine also may act on gamma-aminobutyric acid neurons of the posterior hypothalamus to suppress sleep promoting pathways.23 The net effect is that caffeine increases vigilance, alertness, and decreases sleepiness” (Hershner and Chervin 2014). This explains that caffeine interrupts your brain in ways to suppress your sleep allowing you not to get sleepy…

stressor. Let’s take your neighbor's fat cat, Fuzzy, and introduce an aggressive Husky that makes a bee-line for him when he’s let off his leash. When Fuzzy sees the dog he experiences a stress response to the danger. The danger is processed in hypothalamus inside fuzzy’s brain, which releases a hormone called CRH. This hormone signals the pituitary gland to activate the stress response. The adrenal glands release steroid hormones that speeds up his heart rate and gives fuzzy that extra energy…

One of the more obvious signs of thirst is when our mouths get dry. Our bodies can detect that we are in need of water due to the osmoreceptors located in the hypothalamus (Saladin, 2015. p. 927.). According to Saladin, these are a bunch of neurons that can tell when the osmolarity in our plasma has increased and we are starting to become dehydrated. Osmoreceptors can also tell if we have low blood pressure, which…

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.)…

that something is not right. Our almost last stop is the limbic system. The limbic system has three parts that includes the hippocampus (plays a part in permitting memories and emotions.), amygdala (allow emotions to occur and be experienced), and hypothalamus (regulates the body’s homeostasis). The last stop on our brain journey is the cerebrum which is the largest part of the brain. But first, the cerebrum also has a cerebral cortex.…

Sleep, is an important function that effects everyone. Without an adequate amount of sleep, one would be at risk for not only diseases, but also effects one executive functions. While this might be easy to say, some may not be able to sleep because of a disease such as Fatal Familial Insomnia (FFI) which apparently effects forty different families worldwide (Fatal Familial Insomnia 1:40-1:52). Before one would know more about a disease like that, the first thing to know is what is sleep,…

The intention of this systematic review of literature is to evaluate the validity of chiropractic as a specific tool in the management of infertility. The challenge in all of this is not only to understand the role of vertebral subluxation on fertility but to understand infertility as a whole. Epidemiology Infertility is defined as the failure to reproduce after twelve months of unprotected sexual intercourse. It is estimated that between 50 and 80 million couples of childbearing age are…

Simply put, obesity can be defined as a condition in which a person has too much body fat. It is not an issue that has recently appeared in modern times, but has been around since the ancient Egyptians, even having records of treatment dating back to the Hippocratic era. According to the Centers for Disease Control and Prevention, approximately 35% of adults in the United States are obese. Alarmingly enough, it was reported in the early 2000s that 16-18% of children and teens in the United…

obesity is we need to look at adipose tissue and where the action takes place and what does it effect. The hormone that adipose tissue secretes is Leptin, this hormone helps in the regulate insulin sensitivity. Leptin acts on receptor sites in the hypothalamus and helps to suppress the appetite as well as has a role in regulating temperature. When there is too much adipose tissue a chronic inflammatory response usually happens which is related to an abnormal cytokinine production. When this…

neurotransmitter that sends messages from the brain and different nerve cells in the body. Dopamine is considered a chemical that is produced in three different areas of the brain. The areas of the brain that are affected by Dopamine are the hypothalamus, substantia nigra pars compacta and ventral tegmental area. Dopamine is linked to movement, memory, attention, inhibition of prolactin production, learning, sleep, mood, pleasurable reward, behavior, pain processing and cognition in the…
