Which part of a neuron transmits information?

• A. Soma
• B. Dendrite
• C. Myelin sheath
• D. Axon

Answer: (D)

The main idea here is how a neuron sends information. The message travels along the axon, carrying the nerve impulse from the cell body toward other neurons, muscles, or glands. The axon is the part that transmits the signal over long distances and releases neurotransmitters at the terminals to communicate with the next cell. The dendrites act as input receivers, gathering signals from other neurons and sending them to the soma for processing, while the myelin sheath speeds up the journey along the axon but doesn’t itself transmit the message. So the axon is the structure that conveys information onward to its destination.
