_________ are empty spaces across which neurons communicate, while _________ are the parts of the neuron that receive messages from other neurons. A. Synapses; axons B. Axons; synapses C. Dendrites; synapses D. Synapses; dendrites

• Synapses; dendrites

Explanation:

The region between one neuron's axon and the other neuron's dendrites is called a synapse. A neuron has three main parts. There is the axon which transmits the impulse from one neuron to the next neuron. The soma or cell body has mitochondria and other organelles to process and amplify the impulse. Then, there is the dendrite which extend from the cell body and which receives messages from other nerve cells.
