Which of the following is not capable of impulse conduction?
Correct answer: D. All of the above are non-impulse conductors
- A. Schwann cell
- B. Epidermal cell
- C. Microglia
- D. All of the above are non-impulse conductors
Explanation
The correct answer is all of the above are non-impulse conductors. While Schwann cells contribute significantly to impulse conduction in the peripheral nervous system, they themselves do not actively conduct electrical impulses like neurons.

About Coordination and Control
Coordination depends on receptors, neurons, synapses and nerve impulses, with reflex actions traced through the reflex arc and the roles of major brain regions. Chemical coordination covers endocrine glands and hormones, including how hormones regulate growth, metabolism, reproduction and internal balance, unlike rapid nervous control.
