Question

Poliovirus affects which pathway during paralysis of muscles?

(a) Motor Pathway

(b) Sensory Pathway

(c) Inter-neuron Pathway

(d) Intra-neuron Pathway

I got this question in an international level competition.

My enquiry is from Viral Diseases in Humans-2 topic in portion Human Health and Disease of Biology – Class 12

Answer 1

Right choice is (a) Motor Pathway

The best explanation: During the paralytic stage, motor nerves are affected resulting in atrophy of muscles, generally of arms and legs but may affect those of diaphragm, larynx and pharynx. So, Motor Pathway is affected during the paralysis of muscles.
