NERVOUS SYSTEM - Neuroglia (Helper Cells)

Question 1

What is the function of neuroglia?

Answer 1

Helper cells that support neurons; outnumber neurons >50:1.

Question 2

CNS Neuroglia: Astrocytes

Answer 2

Protect, nourish, and repair neurons; form the Blood-Brain Barrier (BBB).

Question 3

CNS Neuroglia: Oligodendrocytes

Answer 3

Myelination in CNS; no neurolemma.

Question 4

CNS Neuroglia: Microglia

Answer 4

Phagocytosis in CNS; involved in pruning.

Question 5

CNS Neuroglia: Ependymal cells

Answer 5

Produce cerebrospinal fluid in choroid plexuses.

Question 6

PNS Neuroglia: Schwann cells (Neurolemmocytes)

Answer 6

Produce myelin sheath in PNS; cell membrane is the neurilemma.

Question 7

PNS Neuroglia: Satellite cells

Answer 7

Protect neurons in ganglia.
