...n action potential” (Alberts, et al., 2013) .The neurotransmitter is broken down by its enzymes and returns in to the presynaptic membrane via endocytosis in vesicles, to prevent over excitation of the cell due to continuous flow of signal (Willmer, et al., 2005).
To conclude the process that govern nervous impulses and synaptic signalling is what enables our cells to coordinate and react to stimuli. The nervous system does more than just transmit signal from one place to another: they add weak signals together (summation), filter out unnecessary low level signals, prevents overstimulation and interprets and registers information received from the senses. Nervous impulses and synaptic signalling are imperative as it is what allows us to touch, speak, move without falling and to react to unfamiliar stimulus very rapidly, the nervous system is what permits our survival.

- Introduction Neurological procedures can lead to significant postoperative deficits. It is important for physicians to assess nervous system function intraoperatively so that any deficits can be corrected before they become permanent. The oldest method of assessing spinal cord function is with the Stagnara wake up test where patients are awoken in the middle of surgery in order to assess motor function(1). Once the neurological status of the patient is evaluated, the patient would be reanesthetized and the surgery would resume.... [tags: Nervous system, Central nervous system]

- Introduction Like a detective who examines criminality, a physician analyzes and identifies illnesses. Most people are unaware of the similarities in symptoms of most diseases, which is why it is important to see a specialist to properly diagnosis any medical conditions. For instance, endocrine system (ES) disorders and central-nervous system disorders display psychological symptoms that most regular civilians would consider to be psychological disorders, such as anxiety or mood swings. However, it is crucial to recognize that a disruption in the functions of both the endocrine system and central nervous system can generate mental disorder-like symptoms, thus it is worth noting the roles...

- 1. Throughout this activity, one of the main scientific principles can be related to the nervous system and the concept of having a reaction time through different means of stimuli. Individuals interacting with the board are exposed to a light, sound or touch stimulus. When the stimulus is created, there is a signal that is first formed within the peripheral nervous system (PNS). The PNS is consisted of nerves that connect the brain and spinal cord to the muscles of the body, sense organs, glands and other tissues (Widmaier et al, 2014, p....

- For my project, I will be covering the nervous system. Some processes I will cover will be brain function in relation to nerves, and how age changes this. varies as people pass from childhood through adulthood to old age. From young age to adulthood, there is a spike in brain function, it steadies in adulthood, and then declines in old age, but different aspects of the brain change at different times. Since the nervous system is controlled by the brain, it is affected drastically. Some specific parts of the nervous system that I will explain will be the autonomic nervous system(made up of the sympathetic nervous system and the parasympathetic nervous system), and the enteric nervous system....

- urons are not the only cells that occupied the central nervous system (CNS). In fact, neurons are outnumbered by supportive non-excitable cells, collectively called neuroglia (a.k.a. glia). 1.2.The term glia was coined by Rudolph Virchow in 1859 to indicate the “connective tissue” surrounding the neurons (glia came from Greek meaning glue. However, the combination of the activities of glial cells and neurons is crucial for brain functions (Steward 2000). There are three types of glial cells in the CNS that can be distinguished by size and embryonic origin: oligodendrocytes (a.k.a.... [tags: Neuron, Nervous system, Central nervous system]

- The nervous system is a network of cells that take messages from the brain and spinal cord to other parts of the body. The nervous system is made up of the Central Nervous System and the Peripheral Nervous System. The Central Nervous System has two main parts; the brain and the spinal cord. While the Peripheral Nervous System has the Somatic and the Autonomic Nervous systems included within it. The Central NS is broken down by two parts the brain and the spinal cord. The brain is protected by the scull and has a mushroom like shape.... [tags: Brain, Nervous system, Central nervous system]

- Someone is sitting at a restaurant bar. A waitress walks over handing out free shots, so he takes one. One leads to two, two leads to three, and so on. Before he realizes it, he is talking louder than ever, tripping over his own feet, and causing a scene. Toward the end of the night, he walks into someone’s table, as he is heading out of the restaurant, knocking over their meals. He tries to say something, but all that comes out is mumbling. The next morning, he is feeling dizzy, has a pounding headache, and does not remember anything from the night before.... [tags: Nervous system, Brain, Central nervous system]

- The Autonomic Nervous System Over tens of millions of years of evolution, the human body has effectively become one of the most intricate and advanced mechanisms that mankind has ever discovered. It has developed natural abilities and functions that continue to astonish the science community everyday. One of the most awe-inspiring structures found within the human body is the autonomic nervous system, which is largely responsible for regulating physiological processes and maintaining an essential homeostasis within the body in order for it to survive....

- The nervous system is one of the most intricate and fundamental systems within the human body. It is constructed from specialised cells called neurons (Willmer, et al., 2005). Information from a stimulus is carried by neurons as chemical and electrical signals to the central nervous system or CNS, electrical signals in particular are imperative as they carry “time-sensitive information rapidly and over a long distance” (Kandel, et al., 2000). A neuron has a cell body, and within it is a nucleus.... [tags: Action potential, Neuron, Nervous system, Axon]
