Chapter 14 - B - Glial Cells, Myelination, Regeneration

Question 1

What are Ependymal Cells?

Answer 1

Ciliated cuboidal epithelial cells that line the ventricles of the brain and central canal of the spinal cord, and are a type of glial cell.

Question 2

What are Satellite cells?

Neurolemmocyte

Question 4

How do schwann cells and oligodendrocytes differ?

Answer 4

Schwann cells only myelinate one part of one axon, and aid in axon regeneration. Oligodendrocytes myelinate multiple parts of multiple axons.

Answer 5

Connective tissue surrounding each axon in a nerve

Question 6

What is the Perineurium?

Answer 6
