What else is affected?
Other than the CNS, the PNS (peripheral nervous system), the endocrine system, as well as the muscular system are greatly affected. The endocrine system is in charge of secreting hormones that regulate growth. The muscular system is in charge of creating movement, and creating a shape, or a posture for the body. Both are affected in a similar way. This way is that after the poliovirus kills the cells, the growth and the movement is disrupted because because of the dead cells. This makes an abstract shape for the muscles, and it can be very painful for the human being.
