What are the key components of a neuron?

The choice that identifies the key components of a neuron is accurate because it includes the soma, dendrites, axon, and terminal buttons, which are fundamental structures of a neuron.

The soma, or cell body, houses the nucleus and organelles, serving as the metabolic center of the neuron. Dendrites are branch-like structures that receive signals from other neurons, facilitating communication within the nervous system. The axon is a long projection that transmits electrical impulses away from the soma to other neurons or muscles. Finally, terminal buttons, located at the end of the axon, release neurotransmitters that carry the signal across the synapse to the next neuron. Collectively, these components are essential for the neuron’s function in relaying information throughout the body.

Other options include components that do not accurately represent the structure of a neuron or contain misleading information, such as the cerebral cortex, which is not part of a single neuron but rather a layer of the brain associated with various higher-level functions, or the synapse, which refers to the junction between neurons rather than a component of a single neuron itself.
