|In nerve injury, nerves are fragile and can be damaged or destroyed by pressure, stretching or cutting. A nerve injury can stop signals to and from the brain, due to which muscles cannot work properly, and a loss of feeling in the damaged area or the injured area. Nerve injury can be classified into three types: Neuropraxia, Axonotmesis, Neurotmesis. Neuropraxia considered as the physiologic blockage of nerve. Axonotmesis includes anatomic disruption of axon with little disruption of connective tissue. Neurotmesis involves anatomic disruption of axon and connective tissue.
Open access to the scientific literature means the removal of barriers (including price barriers) from accessing scholarly work. There are two parallel roads towards open access: Open Access articles and self-archiving. Open Access articles are immediately, freely available on their Web site, a model mostly funded by charges paid by the author (usually through a research grant). The alternative for a researcher is self-archiving (i.e., to publish in a traditional journal, where only subscribers have immediate access, but to make the article available on their personal and/or institutional Web sites (including so-called repositories or archives)), which is a practice allowed by many scholarly journals.
