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.
General Discussion. Post-polio syndrome (PPS) is a syndrome that affects some people who have had polio (poliomyelitis) and occurs many years (typically from 10 to 40 years) after recovery from the initial infection. It is characterized by the development of progressive weakness in muscles that were affected by the original polio infection.
