They help the neuron receive messages from the dendrites of another neuron.
The correct answer is: They help the neuron receive messages from the dendrites of another neuron.
Dendrites are branch-like structures that extend from the cell body of a neuron. They are responsible for receiving incoming signals or messages from other neurons. These signals can be either excitatory (encouraging the neuron to fire an action potential) or inhibitory (preventing the neuron from firing an action potential). By receiving messages from the dendrites of another neuron, the dendrites help the neuron to integrate and process information from multiple sources, which is essential for the overall function of nerve cells.
