|It is also called as nerve cell. Neurons are connected to each other to form a neural network. Signals between the neurons occur via synapse. Neuron consists of nucleus, dendrites, axon, axon terminals. Axon is covered by myelin sheath but not continuously, places where myelin sheath covering is absent is called as nodes of ranvier. Neurons that simply signals the other neuron are called as interneurons.
Review articles are the summary of current state of understanding on a particular research topic. They analyze or discuss research previously published by scientist and academicians rather than reporting novel research results.
Review article comes in the form of systematic reviews and literature reviews and are a form of secondary literature. Systematic reviews determine an objective list of criteria, and find all previously published original research papers that meet the criteria. They then compare the results presented in these papers. Literature reviews, by contrast, provide a summary of what the authors believe are the best and most relevant prior publications.
