information traveling to and from the brain?
A. sympathetic chain
B. spinal cord
C. sensory nerves
D. peripheral nerves
Which of the following acts primarily as a highway for
information traveling to and from the brain?
A. sympathetic chain
B. spinal cord
The spinal cord carries impulses to and
from the brain.

Board
The spinal cord runs through what vertebral opening?
A. intervertebral foramina
B. inferior vertebral notch
C. vertebral foramina
D. superior vertebral notch
The spinal cord runs through what vertebral opening?
A. intervertebral foramina
C. vertebral foramina
The spinal cord runs through the vertebral
canal, formed by all of the vertebral foramina.

Denticulate ligaments are specializations of what meningeal
membrane?
A. dura mater
B. arachnoid mater
C. pia mater
D. subdural mater
Denticulate ligaments are specializations of what meningeal
membrane?
A. dura mater
C. pia mater
The denticulate ligament is a scallop-shaped lateral
extension of the pia mater.

Board
In the cervical vertebrae and the thoracic vertebrae, spinal
nerves corresponding to the vertebrae emerge where,
respectively (excluding T1)?
A. above, below
B. above, above
C. below, above
D. below, below
In the cervical vertebrae and the thoracic vertebrae, spinal
nerves corresponding to the vertebrae emerge where,
respectively (excluding T1)?
A. above, below
C. below, above
Because there are 8 cervical spinal nerves, they
pass over their vertebra; all others pass under.

Board
The cauda equina typically lies in the lumbar cistern below
which vertebral level in an adult?
A. L3/4
B. S2
C. T12
D. L1/L2
The cauda equina typically lies in the lumbar cistern below
which vertebral level in an adult?
A. L3/4
D. L1/L2
The spinal cord ends at L1/2 level, and the cauda
equina is the collection of nerve rootlets below it.
Back to
Board
What spinal cord enlargements contain upper and lower
limb motor neurons?
A. cervical and thoracic
B. cervical and lumbar
C. thoracic and lumbar
D. thoracic and sacral
What spinal cord enlargements contain upper and lower
limb motor neurons?
B. cervical and lumbar
C. thoracic and lumbar
The cervical enlargement supplies the upper limbs,
while the lumbar enlargement supplies the lower limbs.

Board
Where, in the spinal cord, are the motor neurons that
innervate skeletal muscle?
A. lateral horn
B. dorsal horn
C. ventral horn
D. medial horn
Where, in the spinal cord, are the motor neurons that
innervate skeletal muscle?
A. lateral horn
C. ventral horn
Motor neuron cell bodies lie in the ventral horn, while
autonomic neuron cell bodies lie in the lateral horn and
sensory fibers synapse on cells in the dorsal horn.

the body?
A. 33, 31
B. 33, 12
C. 31, 33
D. 12, 33
How many vertebrae and spinal nerves, respectively, are in
the body?
A. 33, 31
C. 31, 33
There are 33 vertebrae, 31 pairs of spinal
nerves, and 12 pairs of cranial nerves.
Back to
Board
What type of fibers are carried by the dorsal roots and
rootlets?
A. motor
B. efferent
C. afferent
D. sympathetic
What type of fibers are carried by the dorsal roots and
rootlets?
B. efferent
C. afferent
Dorsal rootlets and roots carry afferent, sensory
fibers to the dorsal horn, where they synapse.
Back to
Board
What types of fibers are found within every spinal nerve?
A. motor
B. sensory
C. motor and sensory
D. sympathetic
What types of fibers are found within every spinal nerve?
A. motor
B. sensory
C. motor and sensory
D. sympathetic
Every spinal nerve carries both motor and sensory
fibers.

Board
Axons innervating deep back muscles and muscles of the
limb and trunk travel in what rami, respectively?
A. ventral, dorsal
B. ventral, ventral
C. dorsal, dorsal
D. dorsal, ventral
Axons innervating deep back muscles and muscles of the
limb and trunk travel in what rami, respectively?
C. dorsal, dorsal
D. dorsal, ventral
Deep back muscles are innervated by dorsal primary
rami, while ventral rami innervate limb muscles.
Back to
Board
Which meningeal membrane layer forms the sleeves for the
ventral and dorsal roots as they exit the intervertebral
foramina?
A. dura mater
B. arachnoid mater
C. pia mater
D. subarachnoid mater
Which meningeal membrane layer forms the sleeves for the
ventral and dorsal roots as they exit the intervertebral
foramina?
A. dura mater
B. arachnoid mater
Dura mater forms a sleeve around nerve rootlets
as they pass into the intervertebral foramen.

Board
Which of the following is NOT a mixed nerve?
A. spinal nerve
B. ventral rami
C. dorsal rami
D. ventral root
Which of the following is NOT a mixed nerve?
B. ventral rami
D. ventral root
Roots are only either sensory or motor, while
rami and spinal nerves are both, or mixed.

Board
Which structure is the most caudal to the foramen
magnum?
A. conus medullaris
B. lumbar enlargement
C. cauda equina
D. coccygeal ligament
Which structure is the most caudal to the foramen
magnum?
C. cauda equina
D. coccygeal ligament
The coccygeal ligament extends from the end of the
dural sac, while lumbar enlargement, conus
medullaris, and cauda equina lie within the dural sac.
