They are branching extensions that receive signals from other neurons and transmit them to the cell body. Dendrites play a crucial role in the communication between neurons, as they receive incoming signals and integrate them to determine whether to transmit the signal further or not. Axons, on the other hand, are responsible for transmitting the signals away from the cell body, while pons and receptors are not directly involved in receiving messages from nerve terminals.Rate this question:
