Neuroscience question

[Condraz23]

OK, so I'm having trouble understanding a particular part of the nervous system.

The skin is connected to the primary somatosensory cortex through afferent (receving information) neurons. As I understand it, there is only one ganglion connecting the central nervous system to the skin, unlike the ganglia of the autonomic nervous system where there is a separate preganglionic ganglion and autonomic ganglion.

Which is the one that connects the skin to the CNS? I always thought it was the primary afferent neurons but I've also got a source which states that the dorsal root ganglions also play a role in this. After all, since it's a pseudounipolar ganglion, the distal process could be the one that connects to the skin and the proximal process could be the one that's connected to the central nervous system (CNS).

Thanks.
