neuroglial cells

Maintain blood brain barrier; provide structural support; regulate ion, nutrient, and dissolved-gas concentrations; absorb and recycle neurotransmitters; form scar tissue after injury

Myelinate CNS axons; provide structural framework

Remove cell debris, wastes, and pathogens by phagocytosis

• Microglia

• Ependymal cells

• Astrocytes

• Satellite cells

Line ventricles (brain) and central canal (spinal cord); assist in producing, circulating, and monitoring cerebrospinal fluid

Satellite cells

Surround neuron cell bodies in ganglia; regulate O2, CO2, nutrient, and neurotransmitter levels around neurons in ganglia

• True

• False

Surround all axons in PNS; myelinate peripheral axons; participate in repair process after injury

Which of the following are neuralgia cells found in the PERIPHERAL NS

• Satellite cells

• Ependymal cells

• Astrocytes

• Schwann cells

Explain the process of myelination. (HINT: involves Schwann Cells)
