Question

The part of the spinal cord indicated by the line is the _____ 
A) posterior (dorsal) root 
B) posterior (dorsal) ramus 
C) anterior (ventral) root

Quizplus · Accepted Answer

The line is indicating the posterior (dorsal) root, which is where sensory neurons enter the spinal cord. The posterior (dorsal) ramus and anterior (ventral) ramus refer to the branches of spinal nerves that exit the spinal column after the posterior (dorsal) and anterior (ventral) roots have merged together. The anterior (ventral) root is where motor neurons exit the spinal cord.
