Final answer:
Axons are responsible for transmitting signals to dendrites, which then pass the signals onto the neuron's soma, integrating them at the axon hillock before sending them on to other cells. This highlights the critical communication pathways between neurons in brain function.
Step-by-step explanation:
When discussing neurons and brain function, it is important to know the role of various components of a neuron. The axon is the part of a neuron that transmits an electrical signal to a target cell. This process begins when a signal is released from the axon terminal and passes through the synapse, ultimately connecting with the dendrites of another neuron. Dendrites specialize in receiving these signals and then transmit them to the soma, or cell body, of the neuron.
Therefore, the correct statement regarding neurons would be 'Axons transmit signals to dendrites,' making option (a) true. Glial cells, such as astrocytes and oligodendrocytes, support neurons by regulating the chemical environment and insulating axons but are not primarily responsible for signaling.
