Which of the following parts of a neuron is correctly matched with its function?

• A. Dendrites - Transmit signals away from the cell body
• B. Cell Body - Releases neurotransmitters into the synapse
• C. Axon - Conducts impulses toward the cell body
• D. Myelin Sheath - Insulates the axon to increase signal speed

Answer: (D)

Verified step by step guidance

1. Understand the basic structure of a neuron, which includes dendrites, a cell body, an axon, and often a myelin sheath.
2. Dendrites are responsible for receiving signals from other neurons and transmitting these signals toward the cell body.
3. The cell body, also known as the soma, contains the nucleus and is responsible for maintaining the neuron's health and processing incoming signals.
4. The axon is a long, slender projection that conducts electrical impulses away from the cell body toward other neurons or muscles.
5. The myelin sheath is a fatty layer that wraps around the axon, providing insulation and increasing the speed of signal transmission along the axon.
