autonomic nervous system
Which glial cells have the most diversity of function?
-Schwann cells
-oligodendrocytes
-ependymal cells
-astrocytes - Answer astrocytes
Which of the following types of glial cells monitors the health of neurons, and
can transform into a special type of macrophage to protect endangered neurons?
-ependymal cells
-microglia
,-astrocytes
-oligodendrocytes - Answer microglia
Ependymal cells line many open cavities in the central nervous system (CNS).
Ependymal cells have cilia on the side of the cell that face these openings. What is the
most likely function of these ciliated cells?
-movement and circulation of cerebrospinal fluid
-exchange of nutrients between the circulatory system and neurons -create myelin
sheaths for CNS cells
-act as macrophage cells to destroy microorganisms or neuronal debris - Answer
movement and circulation of cerebrospinal fluid
Which of the following peripheral nervous system (PNS) neuroglia form the
myelin sheaths around larger nerve fibers in the PNS?
-oligodendrocytes
-satellite cells
-Schwann cells
-astrocytes - Answer Schwann cells
The concentration of ions in the chemical environment surrounding the neurons
must be tightly regulated for neurons to function properly. Which of the following
cells is most responsible for this?
-astrocytes
-satellite cells
-oligodendrocytes
-Schwann cells - Answer astrocytes
, Meningitis can be caused by infection of the central nervous system by bacteria.
Which cells would be most responsible for removing the infection?
-satellite cells
-Schwann cells
-microglia
-oligodendrocytes - Answer microglia
Schwann cells are functionally similar to ________.
-ependymal cells
-microglia
-oligodendrocytes

Which of the following pairings does not fit?
-sensory neurons: afferent neurons
-motor neurons: efferent neurons
-multipolar neurons: peripheral nervous system sensory neurons -association neuron:
interneurons - Answer multipolar neurons: peripheral nervous system sensory neurons
Many neurons have many short, branching extensions called dendrites. What is
the benefit of these structures for a neuron?
-There is a large area for production of chemicals used to signal other neurons.
-There is a large amount of space for myelin to form and make electrical conduction
more efficient.
-There is a large surface area to send signals to other cells.
-The dendrites provide a large surface area for connections from other neurons. - Answer
The dendrites provide a large surface area for connections from other neurons
