The given diagram shows neurons connecting the eye with the central nervous system.With reference to the given diagram, neuron I and neuron II are identified as
Correct answer: B. Sensory, Motor
- A. Relay, Sensory
- B. Sensory, Motor
- C. Motor, Relay
- D. Relay, Motor
Explanation
Neuron 1 is sensory as it carries impulses towards the brain whereas neuron 2 is motor as it carries impulses from the brain to eye. So option B is correct. There is no relay asked so options containg relay are incorrect.

About Neurons and Nerve Impulse
Neurons receive and transmit information through dendrites, the cell body and axons. The topic explains resting potential, depolarization, repolarization, refractory periods and saltatory conduction, followed by synaptic transmission through neurotransmitters. An action potential is distinct from the graded potential produced at a receptor.
