Nervous Tissue: supporting cells

Question 1

what are the four types of central nervous system’s glial cells?

Answer 1

1. astrocytes
2. microglia
3. ependymal cells
4. oligodendrocytes

Question 2

It brace and anchoring neurons to blood capillaries and determines permeability and exchanges between blood capillaries and neurons. It is also the most abundant and versatile neuroglia

Answer 2

astrocytes

Question 3

what type of glial cells protect neurons from harmful substances in blood and control the chemical environment of the brain.

Answer 3

astrocytes

Question 4

it defend CNS cells

Answer 4

microglia

Question 5

it has processes that form myelin sheets around CNS nerve fibers.

Answer 5

oligodendrocytes

Question 6

it lines cerebrospinal fluid-filled cavities

Answer 6

ependymal cells

Question 7

A spiderlike phagocytes that monitors the health of nearby neurons and disposes of debris.

Answer 7

microglia

Question 8

wrap around nerve fibers in the central nervous system and produce myelin sheets

Answer 8

oligodendrocytes

Question 9

Lines cavities of the brain and spinal cord and cilia assist with circulation of cerebrospinal fluid.

Answer 9

ependymal cells

Question 10

two types of PNS glial cells

Answer 10

• schwann cells
• satellite cells

Question 11

this cell protects and cushions neuron cell bodies.

Answer 11

satellite cells

Question 12

the cell that forms myelin sheath around nerve fibers in the PNS.

Answer 12

schwann sells

Question 13

what are the cells (which form myelin) that surround neurons in the PNS?

Answer 13

satellite cells and schwann cells
