NEET Zoology Neuron MCQ Question

Type: MCQ-conceptual-Medium-Class 11

Which of the following statements about neurons and synapses are correct?

A

Dendrites transmit impulses towards the cell body, while axons transmit impulses away from it.

B

Bipolar neurons have multiple dendrites and are typically found in the cerebral cortex.

C

Chemical synapses allow for direct electrical current flow between neurons.

D

Myelinated axons conduct impulses faster than unmyelinated axons due to the presence of nodes of Ranvier.

Correct Answer

Option A

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.
