What are the components of a nerve cell?

1. Cell body, nucleus, dendrites, and axon

2. Dendrites, axon, and synapse

3. Nucleus, mitochondria, and neuron

4. Axon, myelin sheath, and terminal buttons

The correct answer is: Cell body, nucleus, dendrites, and axon

The components of a nerve cell, also known as a neuron, include the cell body, nucleus, dendrites, and axon. The cell body contains the nucleus, which houses the cell's genetic material and is essential for maintaining the neuron's functions. Dendrites are extensions of the neuron that receive signals from other nerve cells, allowing the neuron to communicate with different parts of the nervous system. The axon is a long projection that transmits electrical impulses away from the cell body to other neurons or target tissues, facilitating communication throughout the nervous system. Understanding these components is crucial for comprehending how neurons function and interact. The other choices focus on partial components or structures related to neurons but do not provide the full range of essential parts that collectively describe a nerve cell.
