Poliomyelitis affects:
Correct answer: C. Motor neuron
- A. Sensory neuron
- B. Interneurons
- C. Motor neuron
- D. Autonomic neurons
Explanation
Poliomyelitis mainly targets the motor neurons responsible for voluntary muscle movement, leading to muscle weakness and paralysis. Sensory neurons remain unaffected, so sensation is usually preserved. Interneurons and autonomic neurons are generally not directly attacked by the virus, though severe cases can sometimes interfere with vital functions if the brainstem is involved. Overall, the destruction of motor neurons is the key cause of the characteristic paralysis seen in polio.
