Understanding Neuroglia

What is the primary role of neuroglia in the nervous system?

• To regulate blood pressure

• To transmit nerve impulses

• To provide structural and functional support

• To produce hormones

Which type of neuroglia in the CNS is responsible for maintaining the blood-brain barrier?

• Oligodendrocytes

• Astrocytes

• Microglia

• Ependymal cells

What is the function of ependymal cells in the central nervous system?

• To act as immune cells

• To circulate and produce cerebral spinal fluid

• To provide nutrients to neurons

• To insulate nerve fibers

How do Schwann cells in the peripheral nervous system assist nerve impulses?

• By removing waste products

• By regulating blood flow

• By forming myelin sheaths around axons

• By producing neurotransmitters

What role do satellite cells play in the peripheral nervous system?

• They produce myelin

• They provide structural and metabolic support

• They form the blood-brain barrier

• They transmit nerve signals
