Correct answer: A. Exposed regions of axon
- A. Exposed regions of axon
- B. Insulated regions of axon
- C. Terminal knobs at the end of axon
- D. Schwann cells present at equal distance

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.
