Summary
Onuf's nucleus, which controls sphincter muscles, appears resistant to poliovirus. Unlike other spinal cord motor neurons damaged by the virus, Onuf's nucleus remained preserved in poliomyelitis patients.
Area of Science:
- Neuroscience
- Virology
- Pathology
Background:
- Onuf's nucleus innervates urethral and anal sphincter muscles.
- This nucleus is typically preserved in motoneuron disease.
- Its susceptibility to motoneurotrophic viruses like poliovirus is unknown.
