The White Matter of the Spinal Cord

Question

The white matter of the spinal cord:
A) contains ascending (sensory) and descending (motor) tracts.
B) is surrounded by gray matter.
C) is subdivided into regions called horns.
D) all of these choices

Accepted Answer

The white matter of the spinal cord contains ascending (sensory) and descending (motor) tracts, which are responsible for transmitting signals to and from the brain. The gray matter, not the white matter, is subdivided into regions called horns, and it surrounds the central canal of the spinal cord, not the other way around.
