Astroglia (astrocytes):
Correct answer: B. Support neurons, by attaching to them and to capillaries.
- A. Form cerebrospinal fluid
- B. Support neurons, by attaching to them and to capillaries.
- C. Are phagocytic
- D. Form the myelin of Central Nervous System axons.
Explanation
Astrocytes provide crucial support to neurons in various ways. They have numerous processes that extend to neurons, where they provide physical and metabolic support, regulate neurotransmitter levels, and help form and maintain synapses. Additionally, astrocytes interact with capillaries to regulate blood flow and maintain the blood-brain barrier.

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.
