Step 1: Concept
Human tissues are categorized into four main types: epithelial, connective, muscular, and nervous tissue.
Step 2: Meaning
Connective tissue supports, binds, or separates other tissues or organs.

Step 4: Conclusion
Therefore, a neuron belongs to nervous tissue, not connective tissue.
