Which part of a neuron primarily sends signals away from the cell body to other cells?

• A. Axon
• B. Cell body (soma)
• C. Myelin sheath
• D. Dendrites

Answer: (A)

Verified step by step guidance

1. Understand the basic structure of a neuron, which includes the cell body (soma), dendrites, axon, and sometimes a myelin sheath.
2. Recall that dendrites primarily receive signals from other neurons and transmit them toward the cell body.
3. Recognize that the cell body processes incoming signals but does not primarily send signals away to other cells.
4. Identify the axon as the long, slender projection of the neuron that conducts electrical impulses away from the cell body toward other neurons or effector cells.
5. Note that the myelin sheath is a fatty layer that insulates the axon to speed up signal transmission, but it is not responsible for sending signals itself.
