The function of oligodendroglia is:
Correct answer: D. Identical with that of Schwann cells of the Peripheral Nervous System
- A. Phagocytosis
- B. Secretion of cerebrospinal fluid
- C. To form a connective tissue-like outer covering around ganglia
- D. Identical with that of Schwann cells of the Peripheral Nervous System
Explanation
Oligodendrocytes in the central nervous system (CNS) and Schwann cells in the peripheral nervous system (PNS) both provide support to neurons by forming myelin sheaths around axons. However, they are not identical in function. Oligodendrocytes myelinate multiple axons in the CNS, while Schwann cells myelinate a single axon segment in the PNS.

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.
