What is the function of the dorsal roots of the spinal cord?A. They receive sensory input.B. They control motor output.C. They convey information from the brain to the spinal cord.D. They convey information from the spinal cord to the brain.
The thoracic spinal cord has the smallest dorsal horn area because:
a.
the trunk is the most innervated area of the body and therefore there are more projections into the dorsal horn there.
b.
the trunk is the least innervated area of the body and therefore there are fewer projections into the dorsal horn there.
c.
most of the descending upper motor neurons have already entered the ventral horn.
d.
There are many motor neurons to control the small muscles around the spine.
Spinal nerves are called mixed nerves because they (a) are associated with a pair of dorsal root ganglia. (b) exit at intervertebral foramina. (c) contain sensory and motor fibers. (d) are associated with a pair of dorsal and ventral roots.
