NEET Biology: Neurobiology questions with solutions

Q1. Which is the correct match?

1. Dendrite - Accepts signal / stimulus
2. Dendrite - Sends signal / stimulus
3. Axon-Smallest part of neuron
4. Synaptic knob - Present at the end of dendron

Answer: Dendrite - Accepts signal / stimulus

Dendrites are the branched parts of a neuron that receive signals from other cells or stimuli. Axons carry impulses away from the cell body, and the synaptic knob is at the end of the axon, not the dendron.
