1 Coelomate animals or Coelomata (also known as eucoelomates â true coelom) have a fluid filled body cavity called a coelom /ËsiËlÉm/ with a complete lining called peritoneum derived from mesoderm (one of the three primary tissue layers).n some protostomes, the embryonic blastocoele persists as a body cavity. These protostomes have a fluid filled main body cavity unlined or partially lined with tissue derived from mesoderm.
Polio is a viral disease which may affect the spinal cord causing muscle weakness and paralysis. The polio virus enters the body through the mouth, usually from hands contaminated with the stool of an infected person.
Polio, also called poliomyelitis is a highly contagious infectious disease caused by one of three related viruses. Polio is a very serious disease, which can lead to paralysis or even death. Once a person is exposed to polio, it usually takes about three to five days for symptoms to appear. In about 95 percent of polio cases, infection from the polio virus causes no symptoms or serious effects. In about 5 percent of cases, the polio virus manifests in a mild form (abortive polio) with flu-like symptoms, in a nonparalytic form (aseptic meningitis) or in a severe form called paralytic polio. People who have minor or nonparalytic forms recover completely.
