Question

multiple choice question
which structure in a neuron is responsible for carrying signals away from the cell body?

myelin sheath
synapses
axon
dendrites

Explanation:

• The myelin sheath insulates axons to speed signal transmission, not carry signals away from the cell body.
• Synapses are junctions between neurons for signal transfer, not a signal-carrying structure of a single neuron.
• Axons are the neuron structures that generate and carry electrical signals (action potentials) away from the neuron's cell body to other neurons or target cells.
• Dendrites receive signals and carry them toward the cell body, not away.

Answer:

O axon
