True or False: if false, choose the answer that best corrects the statement.
Neurons are the only important cell type in the nervous system.

• A. True.
• B. False; both neurons and glial cells are important for nervous system function.
• C. False; there are hundreds of cell types in the nervous system, and all of them are important.
• D. False; glial cells are the most important cell type for nervous system function.

Answer: (B)

Verified step by step guidance

1. Identify the statement to evaluate: 'Neurons are the only important cell type in the nervous system.'
2. Understand the role of neurons: Neurons are specialized cells responsible for transmitting information throughout the nervous system via electrical and chemical signals.
3. Consider the role of glial cells: Glial cells support neurons by providing structural support, protection, and nutrition, and are crucial for maintaining homeostasis and forming myelin.
4. Evaluate the statement: Since glial cells also play a vital role in the nervous system, the statement that neurons are the only important cell type is false.
5. Choose the best correction: The correct answer is 'False; both neurons and glial cells are important for nervous system function,' as it acknowledges the significant roles of both cell types.
