Which part of the spinal cord does the dorsal rootlets connect to?

The dorsal rootlets connect to the dorsal horn of the spinal cord. The dorsal horn is a region located in the posterior part of the gray matter of the spinal cord that primarily processes sensory inputs.

Dorsal rootlets carry afferent sensory information from the periphery to the central nervous system. These rootlets emerge from the dorsal root ganglia, where the cell bodies of sensory neurons reside, and enter the dorsal horn to synapse with second-order neurons. This relay is critical for processing sensory modalities such as pain, temperature, and touch.

Understanding this anatomical relationship is essential for grasping how sensory information is integrated and processed within the spinal cord before it is transmitted to higher regions of the brain for further interpretation.
