Frage 2
Frage
Which statements about the external anatomy of the spinal cord are true?
Antworten
-
It ends at the superior border of the second lumbar vertebrae. (L2).
-
It leaves the skull though the foramen magnum.
-
It is within the meningeal sack, which sits inside the spinal cavity.
-
The spinal cavity surrounds the vertebrae.
Frage 3
Frage
The CSF (cerebrospinal fluid) is to provide cushioning as well as nutrients.
Antworten
- True
- False
Frage 4
Frage
From the deepest part to the most superior part, the spinal cord is protected by CSF > Adipose Tissue > Meninges > Vertebrae
Antworten
- True
- False
Frage 5
Frage
Which statement about the external anatomy of the associated features of the spinal cord is false?
Antworten
-
The conus medularis and filum terminale are connective tissue.
-
The filum terminale is an extension of the nerves.
-
The conus medularis is a tapered cone at the distal end of the spinal cord/meningeal sack.
Frage 6
Frage
Spinal nerves are named after the vertebrae/spinal cord region they exit/enter. The spinal cord, from superior region to most inferior region, goes Cervical > Thoracic > Lumbar > Sacrum.
Antworten
- True
- False
Frage 7
Frage
Inferior to the end of the spinal cord, some lumbar and all sacral nerves continue to exit the vertebral column.
Antworten
- True
- False
Frage 8
Frage
Which statement about the cauda equina is false.
Antworten
-
It is the region of the meningeal sack inferior to the spinal cord.
-
At its most inferior point, spinal nerves exit the cauda equina at the coccygeal level.
-
The existence of the cauda equina means that you can only damage your spinal nerves if the spinal cord is damaged.
Frage 9
Frage
The central canal is more of a theoretical or potential space than a real space.
Antworten
- True
- False
Frage 10
Frage
White matter is cell bodies.
Antworten
- True
- False

-
The anterior region of the spinal cord carries ascending information.
-
Damage to the posterior region of the spine affects motor control.

Antworten
- True
- False
Frage 14
Frage
A spinal nerve contains both afferent and efferent information.
Antworten
- True
- False
Frage 15
Frage
The ventral ramus is one of two diverging paths from a spinal nerve, which brings both afferent and efferent information to the posterior of the body.
Antworten
