If dendrites are removed from a neuron what will happen to its ability to receive messages?
Answer and explanation
Correct answer: It will decrease greatly
Dendrites are branched extensions specialized mainly for receiving signals from receptors or neighbouring neurons and directing them toward the cell body. If they are removed, the neuron loses much of its receiving surface and incoming signals cannot be transmitted normally to the cell body. Consequently, its ability to receive messages decreases greatly, making option A correct. The other options either reverse the effect or describe impossible changes in unrelated structures.
