In the Central Nervous system, myelin is formed by:
Correct answer: D. Oligodendroglia
- A. Axons
- B. Dendrites
- C. Microglia
- D. Oligodendroglia
Explanation
Oligodendroglia are specialized glial cells in the central nervous system responsible for myelin formation. They wrap their extensions around the axons of multiple neurons, forming the myelin sheath that insulates and protects the nerve fibers, facilitating faster and more efficient nerve impulse transmission.

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.
