  The nervous system has My most interested system is the nervous system. The nervous system is made up of the brain, the spinal cord, and nerves. One of the most important systems in your body, the nervous system is your body’s control system. It sends, receives, and processes nerve impulses throughout the body. Together, these organs are responsible for the control of the body and communication among its parts. The nervous system has two major parts: the central nervous system (CNS) and the peripheral nervous system (PNS).The central nervous system is the primary center of the body. It is composed of the brain, nerves, and spinal cord. It processes, guide movement and send out sensations throughout the body. The brain sits right in the skull and have four parts to it, the brain stem, cerebrum, cerebellum, and the diencephalon. The spinal cord is a long tube that connects to the brain and down the back of the body. It has 31 segments and there are pair of spinal nerves in each segment. Both motor and sensory nerves are in the spinal cord….show more content…Such as eyes, ears, skin, and other “sensory receptors”. The peripheral nervous system is made up of two parts, somatic nervous system and autonomic nervous system. The somatic system picks up sensory information and its carried to the central nervous system. They also consist of the motor nerve fibers. It sends messages for movement and acts to the skeletal muscle. It sends messages to the brain to give the muscle to give action. The autonomic nervous system is made up of three parts; sympathetic nervous system, parasympathetic nervous system, and enteric nervous system. System controls organs in the body where humans cannot. Like, heartbeat, digestion, andthree general functions: a sensory function, an interpretative function and a motor function. Sensory nerves gather information from inside the body and the outside environment. The nerves then carry the information to central nervous system (CNS). Nervous tissue consists of two main types of cells: neurons and neuroglia. Neurons also so known as nerve cells “) transmit nerve impulses that move information around the body. Central Nervous System and Peripheral Nervous System are Identified as the two major groups of nervous system organs while CNS = brain & spinal cord and PNS nerves that extend from the brain (cranial nerves) and spinal cord (spinal nerves). Sensory receptors respond to stimuli and transmit data about them to the brain. In the skin, receptors detect touch, pressure, vibration, temperature, and pain. Elsewhere in the body, more specialized receptors detect light (see How the eye works), sound (see The mechanism of hearing), smell, and taste. The body nervous system detects the changes affecting the body, make decisions, and stimulate muscles or glands to respond. The responses counteract the effects of the changes, where the nervous system helps maintain homeostasis. Neurons vary in size and shape and also differ in the lengths and sizes because of their axons and dendrites. A neuron has 4 basic parts: the dendrites, the cell body which is also called the soma, the axon and the axon terminal. Dendrites – Extensions from the neuron. Neuropsychological Disorder: Neurological disorders are diseases of the central and peripheral nervous system. In other words, the brain, spinal cord, cranial nerves, peripheral nerves, nerve roots, automatic nervous system, neuromuscular junction, and muscles. These disorders include epilepsy, Alzheimer diseases and other dementias, cerebrovascular diseases including stroke, migraine and other headache disorders, multiple sclerosis, Parkinson’s disease, neuro infections, brain tumours, traumatic disorders of the nervous system such as brain trauma, and neurological disorders as a result of malnutrition. The environment (including lifestyle) plays a significant role in many conditions (for example, diet and exercise in relation to diabetes), but our cellular and bodily responses to the environment may differ according to our DNA. The genetics of the immune system, with enormous variation across the population, determines our response to infection by pathogens. Furthermore, most cancers result from an accumulation of genetic changes that occur through the lifetime of an individual, which may be influenced by environmental factors. Clearly, understanding genetics and the genome as a whole and its variation in the human population, are integral to understanding disease processes and this understanding provides the foundation for curative therapies, beneficial treatments and preventative measures.With so many genetic disorders, it is impossible to include more than a few examples within this review, to illustrate the principles. For further information on specific conditions, there are a number of searchable internet resources that provide a wealth of reliable detail. These include Genetics Home Reference (https://ghr.nlm.nih.gov/), Gene Reviews (https://www.ncbi.nlm.nih.gov/books/NBK1116/), the ‘Education’ section from the National Human Genome Research Institute (https://www.genome.gov/education/) and Online Mendelian Inheritance in Man (https://www.omim.org/). In this review, an understanding and knowledge of basic principles and techniques in molecular biology, such as the structure of DNA and the PCR will be assumed, but explanations and animations of PCR (and some other processes) are available from the DNA Learning Center (https://www.dnalc.org/resources/). The focus here will be on human disease, although much of the research that defines our understanding and the human genome reference sequenceThe complete instructions for generating a human are encoded in the DNA present in our cells: the human genome, comprising roughly 3 billion bp of DNA. Scientists from across the world collaborated in the ‘Human Genome Project’ to generate the first DNA sequence of the entire human genome (published in 2001), with many additions and corrections made in the following years. Genome sequence information for humans and many other species is freely accessible through a number of portals, including the National Center for Biotechnology Information (NCBI; https://www.ncbi.nlm.nih.gov/) and Ensembl (http://www.ensembl.org/), which also provide a wealth of related information.The majority of our DNA is present within the nucleus as chromosomes (the nuclear DNA or nuclear genome), but there is also a small amount of DNA in the mitochondria (the mtDNA or mitochondrial genome). Most individuals possess 23 pairs of chromosomes (Figure 2), therefore much of the DNA content is present in two copies, one from our mother and one from our father.The human nuclear genome encodes roughly 20000 protein-coding genes, which typically consists of both protein-coding (exon) and non-coding (intron) sequencesare many more that perform various roles within the cell, including regulation of expression of other genes.
