=====Nervous tissue===== Is the main component of the two parts of the [[nervous system]]; the [[brain]] and [[spinal cord]] of the [[central nervous system]] (CNS), and the branching [[peripheral nerve]]s of the [[peripheral nervous system]] (PNS), which regulates and controls bodily functions and activity. It is composed of [[neuron]]s, which receive and transmit impulses, and [[neuroglia]], also known as [[glial cell]]s or more commonly as just [[glia]] (from the Greek, meaning glue), which assist the propagation of the nerve impulse as well as providing nutrients to the neuron. Nervous tissue is made up of different types of nerve cells, all of which having an axon, the long stem-like part of the cell that sends action potential signals to the next cell. Functions of the nervous system are sensory input, integration, control of muscles and glands, homeostasis, and mental activity. [[Electrospinning]] is the process by which a [[scaffold]] containing micrometer and nanometer diameter [[fiber]]s are drawn from a [[polymer]] solution or melt using a large voltage gradient between a polymer emitting source and a grounded collector. Ramakrishna and colleagues first investigated electrospun fibers for neural applications in 2004. After this initial study, electrospun fibers are increasingly investigated for [[neural tissue]] engineering applications ((Schaub NJ, Johnson CD, Cooper B, Gilbert RJ.
