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. I will go in depth into what makes these things work, by explaining the neuron-(I will also explain how neurons are developed, the migration phase, and the difference between neuroblasts and neurons) its axons, and its intricate neural networks. I will also cover glial cells. I will explain where nervous systems are found, and how they vary in complexity. One of the more extensive parts will be the synapses of neurons, their circuits and systems, reflexes and other stimulus-response circuits, and intrinsic pattern generation. I will also explain the formation of nervous tissue, and I will integrate the evolution of the nervous system into all of this. Since the nervous system is such a broad topic, I probably have left some things out. If you can think of anything that you believe I should include in the project, let me know. The nervous system is composed of all nerve tissues in the body. The functions of nerve tissue are to receive stimuli, transmit stimuli to nervous centers, and to initiate response. The nervous system is similar to the en...

One nervous-system devastating disease is Multiple sclerosis, or MS. It involves an immune-mediated process in which an abnormal response of the bodies immune system is directed against and CNS. Within the CNS, the immune system attacks tmyelin, the conductor for nerve fibers. The damaged myelin then forms scar tissue, and when any part of the myelin sheath or nerve fiber is damaged or destroyed, nerve impulses traveling to and from the brain and spinal cord are distorted or interrupted, producing a wide variety of symptoms. The disease is thought to be triggered by a genetically susceptible individual by a combination of environmental factors.

Essay Autonomic Nervous Systems : The 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....   [tags: Parasympathetic nervous system]

Central Nervous Systems And The Peripheral Nervous System Essay

- The nervous system is made up of two major parts: the central nervous system and the peripheral nervous system. The central system is the main command center for the body and is comprised of the brain and spinal cord. The peripheral nervous system contains a network of nerves that connect the rest of the body to the central nervous system. The central nervous system and the peripheral nervous system work together to collect information from within the body and from the environment outside it. The systems process all the collected information and send instructions to the rest of the body, to obtain an appropriate response....   [tags: Nervous system, Neuron, Central nervous system]

The Nervous Systems Essay

- The processes of communication between distinct tissues and organs Among various types of organ systems, the nervous system is one of the most important one in human body. It is responsible for producing, controlling and guiding our thoughts and responses to the world around us according to James W. Pennebaker (2012). During embryological development, the cells that form nervous system are incredibly specialised and work complexly than the cells that form skin or other body parts. Neurosecretory cells are one of the examples of specialised nervous system cells that produce neurosecretions....   [tags: anatomy, nervous system]

A Study Of Nervous Systems, Anatomy And Physiology Essay

- Question 6-The approach that fascinates me the most is neuroscience; furthermore, neuroscience is the study of nervous systems, anatomy and physiology. Neuroscience is preoccupied with both the organization of the system in humans, animals and their purposes. Neuroscience proposes a body of information that serves as an infrastructure for comprehending how cognitive operations are conveyed. Cognitive neuroscience focuses on cognitive processes, which are visual, object recognition, attention, memory, problem solving and language (Friedenberg and Silverman, 2012)....   [tags: Human brain, Brain, Nervous system]

Evolution Of Mammalian Nervous Systems Essay

- In brief, what is known about the evolution of glia in mammalian nervous systems. Does this knowledge provide any insights into the functions of glia. In your answer, include the three major types of glia: astrocytes, oligodendroglia/Schwann cells, and microglia. All the glia cells (astrocytes, oligodendrocytes and microglia) including neurons are developed from the neuro epithelial progenitor cells in embryonic neural tube. NPCs are transformed to radial glia which are progenitor’s cells of neurons and microglia....   [tags: Neuron, Nervous system, Action potential, Myelin]

Essay about The Nervous System And The Brain

- 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 System Of The Nervous System Essay

- Every organism (vertebrate or invertebrate) needs a system to function. One of these systems is Nervous System which helps in transporting the messages from brain to different parts of body. It is made up of central nervous system and peripheral nervous system. In nervous system, neurons which are considered as major player receive and transport the electric and chemical signals and are also known as communication center. Neurons are again classifies into three types; sensory neurons which transport the material carried from external stimuli, interneurons which associates the neurons within the central nervous system and motor neurons which carries signals to effe...   [tags: Action potential, Nervous system, Neuron, Axon]

Essay about The Nervous System

- 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]

The Human Nervous System Essay

- The human nervous system did not evolve singularly to survive in environments free of stress and danger. The human nervous system has developed to survive also in the face of danger. In addition, chronic and acute stress must be adapted to as necessary. The flexibility called for in these cases lies in the neural circuits that are responsible for our defensive strategies, commonly referred to as our fight or flight behaviors. These neural circuits are our most primitive and earliest developed. The human nervous system relies on three neural circuits....   [tags: Nervous system, Brain, Acetylcholine]
