Essay On The Endocrine System

These molecules are found throughout the body, namely in areas such as the brain, the organs, immune cells, glands and connective tissues. In each tissue, the endocannabinoid system performs different tasks but the overall aim is the same. This is that of homeostasis (TruthOnPot.com, 2013). Homeostasis is the control of a stable internal environment. The endocannabinoid system is a unique system in the brain that affects important functions such how a person feels, moves and reacts (The Science of the Endocannabinoid System, 2011).

The next hormone is thyrotropin, which is another releasing hormone. It is actually produced by the pituitary gland but, the hypothalamus gland regulates its production. This is the part of the brain that is accountable for maintain body temperature, thirst and hunger. It triggers a thyroid-stimulating hormone and prolactin to be released from the anterior pituitary. This hormone has been used to clinically treat spinocerebellar degeneration and disturbance of consciousness in humans.

In response to this decline, pancreas liberate a second islet hormone, glucagon, produced by alpha cells which works opposite to insulin and help the body to regulate the utilisation of glucose and fat. When blood sugar level drops a few hours after eating, the production of glucagon in the pancreas is triggered that stimulates the liver to convert stored glycogen into glucose and release back them into bloodstream. This process is known as glycogenolysis. In addition to the conversion of glycogen, glucagon also inhibits the liver from intake of glucose from the bloodstream and keeps glucose levels stable during hypoglycemia. Glucagon also causes the liver to undergo gluconeogenesis, a process that allows it to absorb non-carbohydrates substrate, amino acids, from the blood and convert them into glucose.

Describe how the hormones of the pancreas regulate the concentration of glucose in the blood (4 points). Insulin is used by the pancreas in response to when the body’s level of blood glucose is too high, and glucagon is inhibited. Insulin performs the job of taking glucose into the liver and helps store glucose as glycogen within the body. When the blood glucose level of the body gets to low the body will inhibit the secretion of insulin, so that glucagon can do its job. What glucagon does is it takes the stored glycogen and lets it be released back out into the bloodstream so the body can have more energy.

TAQ 1: a) b) The mammalian nervous system is split into two. The central nervous system consists of the brain and the spinal cord, which coordinates and controls the movement and activities of the body and the peripheral nervous system, made up of the somatic and autonomic system, which forms the connections between the organs and the central nervous system. The brain and the spinal cord work together to aid the coordination of the body. The brain can be divided into three main regions: the forebrain, midbrain and hindbrain. The forebrain interprets sensory information, thought processes and memory and it also monitors the composition of the blood and temperature on the body.

For example failure to maintain body temperature leads to hypothermia or heatstroke. Failure to maintain energy balance can result in obesity and diabetes. In each of these cases, extremes are potentially dangerous. The endocrine system consist of many glands. These glands secrete chemicals known as hormones.

In today 's society, if we appear to be exhausted, while knowing that we have to be on the run, we turn ourselves to energy drinks. Little do we know that every time we consume a single sip of an energy drink, we are literally creating a crucial complication towards our body. The innumerable quantities of caffeine and sugar that we devour stimulates each and every part of the body. Individuals have been replacing protein bars and other athletic beverages for real food (McCarthy). Becoming addicted to energy drinks relates to type 2 diabetes, even long-term effects such as heart issues, but most of all death.

Diabetes mellitus a condition where the body has trouble making and/or using the insulin it needs to regulate its blood sugar levels. We get glucose from food, and when our blood glucose levels get high, insulin is released to activate glucose uptake by various cells. If it isn’t able to do its job properly, glucose will build up in the blood and can lead to hyperglycemia and many complications. Diabetes mellitus is more common than diabetes insipidus, and has 3 types: type 1, type 2, and gestational. Treatments can include lifestyle changes (exercise, diet) as well as insulin

When people do drugs, they enter the brain. When drugs are entered in the brain, they come in between our brain’s natural processing and changes the way it works. Drugs affect three main areas of the brain; the brain stem, the limbic system, and the cerebral cortex. The brain stem is in charge of all the functions in the body. The brain stem links the brain with the spinal cord and moves muscle.

Acting through nuclear receptors, these hormones plays a critical role in cell differentiation during development and helps in maintaining thermo genic and metabolic homeostasis in the adult. Autoimmune disorders of the thyroid
