D) dendrites.
E) glia.

Question

Quizplus · Accepted Answer

Dendrites are the extensions of postsynaptic neurons that provide the main receptive surface for presynaptic neurons. They receive signals from other neurons and transmit those signals to the cell body or soma. Nuclei are found in the cell body of neurons and help to regulate gene expression, while axons are the extensions of the neuron that transmit signals away from the cell body. Glia are non-neuronal cells that provide support and protection for neurons. Therefore, the best choice for the extensions of postsynaptic neurons that provide the main receptive surface for presynaptic neurons is dendrites.
