What is the Nervous System?
The nervous system is in control of the body, your thoughts and movements, it's job is to send and receive messages (Hes.ucfsd.org, 2014). The nervous system is divided into two key parts; The Central Nervous System (CNS) and The Peripheral Nervous System (PNS). The CNS consists of both the brain and the spinal cord where as the PNS is made up from all the nerves which carry the messages (Faculty.washington.edu, 2014).

What is a Neuron?
The cells within the nervous system are called Neurons. Neurons send and receive electro-chemical signals to and from the brain and the nervous system (Enchantedlearning.com, 2014). A Neuron can transmit nerve signals at up to 200 mph! Neurons are similar to other cells as a membrane …show more content…

Most people are over the age of 50 when this disease appears but rarely it can appear in younger patients. (US 1998). It is a progressive nervous system disorder.
It causes:
- Trembling arms and legs.
- Trouble speaking.
- Difficulty coordinating movements.
- Muscular stiffness.
It is also a movement disorder, which means it causes abnormal body movements (Today, 2014). This disease occurs when neurons disintegrate or loose the ability to function properly. There is no known cure for this disease, only treatment to help with the symptoms (Faculty.Washington.edu, 2014).

What is the Endocrine System?
The Endocrine System influences almost every cell, organ and function of our body (Kidshealth.org, 2014). It helps keep the body's hormones and secretion levels in order. The Endocrine System is a group of gland, wher each of them secrete different types of hormones. They all have different jobs to regulate different things such as;
Metabolism
Growth and development
Tissue function
Sexual function
Reproduction
Sleep and mood

    While the respiratory and cardiovascular systems are most reliant on one another, all body systems require a functioning circulatory cycle in order to thrive. Blood circulation and consistent transfer of oxygen to cells is required to maintain cell and tissue life. Disturbances to this process will cause cells and tissues to die (Red Cross 48). This state of balance and functioning body systems is referred to as homeostasis, defined as a “condition of equilibrium in the body’s internal environment due to constant interaction of body’s many regulatory processes” (Tortura 8). Changes or disruptions to homeostasis are regulated by the Endocrine and Nervous systems of the body. The endocrine system is made up of glands placed throughout the body

  • What is Diabetes Mellitus?

    Carbohydrates, mainly glucose, are an important source of energy for living organisms. Some tissues of the body (e.g., brain) need a continuous delivery of glucose. Maintenance of blood glucose concentrations within a normal range is critical to the regulation of normal fuel use by the organs. This is primarily accomplished by the two hormones, Insulin and Glucagon, which are secreted by the alpha and beta cells of the pancreas, respectively. The function of Insulin is to keep the blood glucose in check by helping it to move inside the cells of our body, thereby decreasing its concentration in the blood. Glucagon does exactly the opposite. Other hormones of our body like glucocorticoids, epinephrine and the growth hormone also function like Glucagon.

    The human nervous system is divided into two parts, the central nervous system and the peripheral nervous system. The central nervous system, CNS, is just the brain and spinal cord. The peripheral nervous system, PNS, includes the nerves and neurons that extend outwards from the CNS, to transmit information to your limbs and organs, for example. Communication between your cells is extremely important, neurons are the messengers that relay information to and from your brain. Nerve cells generate electrical signals to transmit information.

    Diabetes refers to a set of several different diseases. It is a serious health problem throughout the world and fourth leading cause of death by disease in the country. All types of diabetes result in too much sugar, or glucos in the blood. To understand why this happens it would helpful if we understand how the body usually works. When we eat, our body breaks down the food into simpler forms such as glucose. The glucose goes into the bloodstream, where it then travels to all the cells in your body. The cells use the glucose for energy. Insulin, a hormone made by the pancreas, helps move the glucose from bloodstream to the cells. The pathophysiology of diabetes mellitus further explains the concept on how this disease works. Pancreas plays an important role of the metabolism of glucose by means of secreting the hormones insulin and glucagon. These hormones where then secreted by Islets of Langerhans directly to the blood. Inadequate secretion of insulin results on impaired metabolism of glucose, carbohydrates, proteins and fats which then result to hyperglycemia and glycosuria. Hyperglycemia is the most frequently observed sign of diabetes and is considered the etiologic source of diabetic complications both in the body and in the eye. On the other hand, glucagon is the hormone that opposes the act of insulin. It is secreted when blood glucose levels fall.

    The pancreas uses these two hormones in order to monitor blood glucose levels. After a meal, blood glucose usually rises. This is when insulin secretion will start (Nussey S, Whitehead S. “Endocrinology: An Integrated Approach”). Consequently, blood glucose decrease to the normal range. This is how insulin maintains blood levels when is high. However, when blood level falls below normal range, glucagon comes into play. Low blood glucose occurs usually when hungry and during exercise. This will then triggers glucagon secretion. When blood level falls, the body goes into imbalance. Hence is why in order to maintain homeostasis glucagon is crucial. The body will tell the pancreas to increase more glucose and the pancreas will secrete glucagon by taking glycogen from the liver to produce glucose. The glucose will produce energy and will make blood glucose concentration increase (Homeostasis of Insulin and Glucose, Abpischools.org). When the pancreas cannot maintain homeostasis, many problems will arise in the body. When the pancreas fails to produce insulin, type 1 and 2 diabetes can occur. For those with type 1 diabetes, insulin injections will be needed in order to regulate blood glucose level, otherwise, glucose levels will be out of control. For type 2 diabetes, they are not insulin dependent like type 1, however, the body does not create enough in the body. When blood glucose

    This is a neurodegenerative disease, meaning it results in progressive loss or death of neurons. It often starts off with effecting simple motor skills like writing and holding things, after a few months usually patients start losing the ability to walk, talk, or move any of their limbs. Although the brain trauma is what causes it, ALS has little-no-effect on the brain. This fatal disease is typically diagnosed around age 60 and most patients are given about 3-5 years to live after being diagnosed. It has been found that 10% of cases are shown as genetic. It was brought to attention that athletes were beginning to get diagnosed with ALS at a younger age than most. After extensive research in the early 2000’s, Brain Analyst, Dr. Mckee ran tests and finally came to the conclusion that the toxic proteins in the brains of ALS patients were coming from repeated blows to the head. It was then made evident why so many athletes in contact sports such as football, soccer, boxing, etc… were being diagnosed at such a young age and more frequently than

    The pancreas, in addition to its digestive process has two important hormones, Insulin and Glucagon which are important for the maintenance of blood glucose level at a narrow range. Not only glucose, but also they are important for protein and lipid metabolism. Glucagon is secreted by the alpha cells of the islet of Langerhans and Insulin is secreted by the beta cells of Langerhans. Both are secreted to portal vein. (8)

    "Neurones monitor or control specific cells or groups of cells" (Martini et al. 2014). The nervous response is rapid, however precise and short-lived, due to the fact that neurotransmitters are broken down and recycled very quickly after they have diffused across the synaptic cleft - in contrast, not all life processes are short-lived, and many require a longer response time. For example; the body continually maintains reproductive capabilities for many years, and other life processes such as growth and development require responses with a long-life span. In addition, not all of the cells in the body are innervated, which means that some cells in the body cannot be reached by the nervous system. As such it is evident that hormones have a major role to play in cellular communication, and the nervous system on its own would not suffice. (Martini et al.

    The nervous system’s main function is to coordinate all of the activities in the body. The main organs are the cerebellum, which controls and coordinates movement. The cerebrum, is the center for conscious thought, learning, and memory. The last main organ is the brain stem. The brain stem keeps the automatic systems in your body working. Problems of the nervous system include, epilepsy, Alzheimer’s, and multiple sclerosis. You can care for your nervous system by wearing a seatbelt, wearing a helmet, and by not using drugs or alcohol. Something very confusing about the nervous system is that the left side of human brain controls the right side of the body and the right side of the brain controls the left side of the body!

    Nervous system is one of the major organ systems that is responsible for the coordination of biological activities inside the body through cells called neurons. It is composed of the brain and spinal cord which are surrounded by protective layers of bone and membrane tissues called meninges. There are two major divisions in the nervous system; first one is the central nervous system (CNS) and the other being the peripheral nervous system (PNS). The CNS is composed of the brain, spinal cord, and retina while the PNS includes the sensory neurons, ganglia, and connecting neurons. The nervous system applies control using nerves; almost as if sending a message by a telephone. The nervous system is fast due to its electrical nature. The nerve cells in this system are connected with each other in a complex manner where the neural pathways would be possible. Neural

    The nervous system is composed of all nerve tissue in the body. This organ system forms a communication and coordination network between all parts of the body. It plays a major role in everyday activities such as breathing, walking even blinking. It is made up of nerve tissues to receive and transmit stimuli to nervous centers and initiate response. Neurons are nerve cells that transmit signals from one location of the body to another. With damage to the nervous system the body would not be able to function properly. The body has to be well taken care of in order to insure proper regulation. The two anatomical divisions that work hand in hand to help regulate the nervous system are the central and peripheral nervous system. According to the Campbell’s seventh edition biology book the nervous system is the most intricately organized data processing system on earth. It is a complex collection of nerves and specialized cells.
