Question

Neuroglia cells show following characters EXCEPT ______________.

• A. Nourishment
• B. Regeneration
• C. Excitability
• D. Phagocytosis

Hint:

Only neurons are excitable; neuroglia are supportive cells.

Answer 1

The Correct Option is C

Step 1: Understanding neuroglia.
Neuroglial cells support, protect, and nourish neurons in the nervous system.
Step 2: Functions of neuroglia.
They provide nourishment, help in regeneration, and some perform phagocytosis.
Step 3: Key difference from neurons.
Neuroglial cells do not conduct nerve impulses and hence are not excitable.
Step 4: Conclusion.
Therefore, excitability is NOT a characteristic of neuroglial cells.
