a) cauda equina

b) posterior median sulcus

c) conus medullaris

d) filum terminale

e) gray commissure

----------------------------------------------------------------------------

2) The caudia equina is formed by:

a) parallel bundles of collagen in connective tissue

b) myelin

c) blood vessels extending downward from the end of the spinal cord

d) spinal nerves extending downward from the end of the spinal cord

e) damange from herpes viruses

----------------------------------------------------------------------------

3) The conus medullaris is the :

a) site of production of cerebrospinal fluid in the spinal cord

b) array of spinal nerves extending downward from the end of the spinal cord

c) extension of the meninges beyond the end of the spinal cord

d) the tapered end of the spinal cord below the lumbar enlargement

e) the upper part of the spinal cord where it is attached to the brain

----------------------------------------------------------------------------

4) At the superior end, the central canal of the spinal cord is continuous with the:

a) foramen magnum

b) brain sinuses

c) internal jugular veins

d) cerebral cortex

e) fourth ventricle

----------------------------------------------------------------------------

5) cell bodies of motor neurons to skeletal muscles are located in the:

a) anterior gray horns

b) lateral gray horns

c) anterior white columns

d) posterior white columns

e) central canal

Explanation / Answer

1) The extension of the meninges inferior to the termination of the spinal cord is called the:

ANS: d) filum terminale

2) The caudia equina is formed by:

ANS: d) spinal nerves extending downward from the end of the spinal cord

Cauda Equina is formed by the nerve roots at the bottom of the spine. The cauda equina is an array of spinal nerves extending downward from the end of spinal cord

3) The conus medullaris is the :

ANS: d) the tapered end of the spinal cord below the lumbar enlargement

The most distal bulbous part of the spinal cord is called the conus medullaris, and its tapering end continues as the filum terminale. The conus medullaris is a tapered end of the spinal cord below the lumbar enlargement

4) At the superior end, the central canal of the spinal cord is continuous with the:

ANS: e) fourth ventricle

5) cell bodies of motor neurons to skeletal muscles are located in the:

ANS: a) Anterior Grey Horn

Motor neurons to skeletal cells are known as alpha motor neurons and their cell bodies are located in anterior gray column.
