If neuronal communication were compared to radio, the _______________ would be the transmitter at the radio station and the _______________ would be the antenna on your car
A) cell bodies; axons
B) dendrites; myelin sheaths
C) myelin sheaths; cell bodies
D) axons; dendrites
Answer: D
Rationale: Dendrites are the small branches radiating from a neuron, which receive messages from other cells and transmit the message toward the cell body. The axon is the structure that transports information from the neuron to other neurons in the form of electrochemical reaction. Conceptually, the dendrites can be thought of as the neuron's receiver, while the axon can be thought of as the transmitter.
