Question
### Transcription for Educational Website: --- Your nerves are unusually fast at sending signals from one nerve to the next nerve or from the nerve to the muscle. A special, fatty covering helps to ensure that the electrical signals move quickly along the neuron. What is the tubular structure of the neuron covered by this special fatty covering? --- ### Image Description: The image illustrates a neuron, highlighting the complex branching typical of dendrites and a central body. The main feature is an arrow pointing to a tubular structure along the neuron which is covered by segments. This likely represents the axon of the neuron, with the segments depicting myelin sheaths, which are the fatty coverings that facilitate faster transmission of electrical signals. The dendrites are shown in blue, spreading out intricately, and the myelin-covered axon is in brown. This visual helps to demonstrate the biological structures involved in neural signal transmission.

**Question:** This tubular structure exiting the neuron transmits information from one neuron to the next neuron. **Options:** A. dendrite B. soma C. axon D. epineurium **Diagram Explanation:** The image includes a diagram of a neuron, highlighting a specific part with an arrow. The highlighted part resembles a long, tubular structure, which is commonly known as the axon. Axons play a crucial role in transmitting electrical impulses from the neuron's cell body to other neurons, muscles, or glands.

Step 1: Introduce about the neurons

Neurons are the cells of the nervous system that are responsible for the generation and conduction of nerve impulses. The nerve impulse is generated by the differential concentration of specific ions across the plasma membrane of a neuron. Specific membrane transporters perform crucial roles during nerve impulse propagation.
