In the diagram of a typical neuron, which structure is responsible for transmitting electrical impulses away from the cell body?

• A. Dendrite
• B. Golgi apparatus
• C. Axon
• D. Nucleus

Answer: (C)

Verified step by step guidance

1. Understand the structure and function of a neuron: A neuron is a specialized cell in the nervous system that transmits electrical signals. It has distinct parts, including the dendrites, cell body (soma), axon, and axon terminals.
2. Learn the role of dendrites: Dendrites are branch-like structures that receive signals from other neurons and transmit them toward the cell body. They are not responsible for transmitting signals away from the cell body.
3. Understand the function of the axon: The axon is a long, slender projection of the neuron that carries electrical impulses away from the cell body toward other neurons, muscles, or glands. This is the structure responsible for transmitting signals away from the cell body.
4. Clarify the role of the Golgi apparatus: The Golgi apparatus is an organelle involved in packaging and transporting proteins and lipids within the cell. It is not directly involved in transmitting electrical impulses in neurons.
5. Review the function of the nucleus: The nucleus is the control center of the cell, containing genetic material (DNA) and regulating cellular activities. While it is essential for the neuron's overall function, it does not transmit electrical impulses.
