NEET Zoology Neuron MCQ Question
Which of the following statements about neurons and synapses are correct?
Dendrites transmit impulses towards the cell body, while axons transmit impulses away from it.
Bipolar neurons have multiple dendrites and are typically found in the cerebral cortex.
Chemical synapses allow for direct electrical current flow between neurons.
Myelinated axons conduct impulses faster than unmyelinated axons due to the presence of nodes of Ranvier.
Correct Answer
Detailed Explanation
Statement A is correct as dendrites do transmit impulses towards the cell body and axons transmit them away. Statement B is incorrect because bipolar neurons have one axon and one dendrite and are found in the retina. Statement C is false as electrical synapses allow direct electrical current flow, while chemical synapses do not. Statement D is partially correct, but it does not directly link to the axon types defined in the NCERT context.
