Each Spinal Nerve is Attached by the _______

Question

Each spinal nerve is attached by the _______.
A) dorsal root
B) spinal ganglion
C) ventral root
D) both A and C

Accepted Answer

Each spinal nerve is attached to the spinal cord by two roots: the dorsal root, which contains sensory fibers, and the ventral root, which contains motor fibers. The spinal ganglion is located on the dorsal root and contains the cell bodies of the sensory neurons. Therefore, choices A, B, and C are all involved in the attachment of spinal nerves, but only choices A and C are the roots directly attached to the spinal cord.
