BIOS 252: WEEK 3 - CENTRAL NERVOUS SYSTEM EXAM QUESTIONS AND
ANSWERS GRADED A+ LATEST UPDATE.
What does the spinal cord pass through?
Foramen ovule
Foramen rotundum
Foramen spinosum
Foramen magnum ANS >> Foramen magnum.
The spinal cord is a cylinder of nervous tissue that arises from the brainstem at
the foramen magnum of the skull.
Which is not considered a region of the spinal cord?
,BIOS 252: WEEK 3
Lumbar
Pelvic
Thoracic
Cervical ANS >> Pelvic
The spinal cord is separated into different regions according to the vertebral
region within which it is housed. The vertebral regions are listed from superior to
inferior as follows: cervical, thoracic, lumbar, sacral, and coccygeal.
Concerning the spinal cord, where is the epidural space?
- Between the arachnoid and pia maters
- External to the dura mater
- Between the arachnoid and dura maters
- Between the two layers of the dura ANS >> External to the dura mater.
The epidural space is above, or on top of, the dura and external to the spinal cord.
It is between the spinal cord and the surrounding vertebrae.
Which of the following is not considered a spinal meninge?
Dura mater
Pia mater
Vertebral mater
Arachnoid mater ANS >> Vertebral mater
, BIOS 252: WEEK 3
The three meningeal layers are (from superficial to deep): dura mater, arachnoid
mater, and pia mater.
Concerning the spinal cord, the subdural space is a real space in which the CSF
circulates.
True
False ANS >> False
The subdural space is only a potential space; normally, the dura and arachnoid are
adherent to each other.
The bundle of nerves inferior to the conus medullaris of the spinal cord is called
what?
Lumbar enlargement
Posterior median sulcus
Cauda equina
Cervical enlargement ANS >> Cauda equina
The cauda equina is a group of nerves and nerve roots stemming from the distal
end of the spinal cord, typically levels L1-L5, and contains axons of nerves that
give both motor and sensory innervation to the pelvic organs and lower limbs.
What is the filum terminable formed from?
