BI-232 OSU Midterm 2 Exam Questions
With Correct Answers
If ____________ are non-functional, the interstitial fluid environment of
| | | | | | | |
|the brain cannot be regulated. (interstitial fluid is the extracellular fluid
| | | | | | | | | | |
around tissue cells, here it is the fluid around brain cells). - CORRECT
| | | | | | | | | | | | |
ANSWER✔✔-astrocytes (Astrocytes are neuroglia that regulate the | | | | | | |
interstitial fluid environment of the brain by working with blood vessels
| | | | | | | | | | |
to form the blood brain barrier.)
| | | | |
Which of the following would you find myelinating the axons of CN (10)
| | | | | | | | | | | | |
(vagus) - CORRECT ANSWER✔✔-Schwann cells
| | | |
A single neuron can exists partially in the PNS and partially in the CNS.
| | | | | | | | | | | | | |
True or False? - CORRECT ANSWER✔✔-True
| | | | |
Why are there two enlargements in the spinal cord? - CORRECT
| | | | | | | | | | |
ANSWER✔✔-Because these regions of the spinal cord have more | | | | | | | | |
neurons to serve more targets. | | | |
True or False? The spinal cord runs the entire length of the vertebral
| | | | | | | | | | | | |
column. - CORRECT ANSWER✔✔-False. The spinal cord runs from the
| | | | | | | | | |
brain to the level of the first or second lumbar vertebrae.
| | | | | | | | | |
, Ganglia are collections of neuron cell bodies in the peripheral nervous
| | | | | | | | | | |
system. What is the equivalent of ganglia in the central nervous system?
| | | | | | | | | | |
|- CORRECT ANSWER✔✔-Grey Matter. Grey matter are collections of
| | | | | | | | |
neuron cell bodies in the central nervous system. White matter are
| | | | | | | | | | |
collections of axons (similar to nerves of the PNS). Nerves are bundles of
| | | | | | | | | | | |
|axons in the peripheral nervous system. Meninges are connective
| | | | | | | | |
tissues that protect the brain and spinal cord.
| | | | | | |
where is the best place for a physician to collect a sample of CSF for
| | | | | | | | | | | | | | |
examination? - CORRECT ANSWER✔✔-Between subarachnoid space | | | | |
What is located in the dorsal root ganglion? - CORRECT ANSWER✔✔-
| | | | | | | | | |
Cell bodies of spinal nerve sensory neurons
| | | | | |
What would you find in the ventral root? - CORRECT ANSWER✔✔-
| | | | | | | | | |
Multipolar neuron axons | |
Which statement best describes the organization of the spinal cord? -
| | | | | | | | | | |
CORRECT ANSWER✔✔-Motor information and sensory information are
| | | | | | |
segregated into specific regions of both gray matter and white matter.
| | | | | | | | | |
True or False? Motor and sensory information are carried on the same
| | | | | | | | | | | |
neuron. - CORRECT ANSWER✔✔-False. Sensory and motor information
| | | | | | | |
are carried on two different nerve cells (neurons). Neurons only carry
| | | | | | | | | | |
