The neural plate is one of the features exclusive to the embryonic development of chordates. It is located dorsally to the notochord. The neural plate is the rudimentary nervous system of the embryo. During early development ,the neural plate is formed from the ectodermal layer . It undergoes changes in the position and arrangement of it's cells to form the brain and the spinal cord which comprises the central nervous system. It forms tissues and eventually organs by the deepening of the groove which forms ridges which eventually folds and fuses to form the neural tube . The tube differentiates into the prosencephalon, the mesencephalon and the rhombencephalon, from which the organs are formed
Drug that demages capsule is used to treat viral infection because Curing a viral infection antibiotics are useless against viral infections. This is because viruses are so simple that they use their host cells to perform their activities for them. So antiviral drugs work differently to antibiotics, by interfering with the viral enzymes instead.
Antiviral drugs are currently only effective against a few viral diseases, such as influenza, herpes, hepatitis B and C and HIV – but research is ongoing. A naturally occurring protein, called interferon (which the body produces to help fight viral infections), can now be produced in the laboratory and is used to treat hepatitis C infections.
