GENERAL HISTOLOGY

Detailed explanation-1: -The root emerges from the posterior part of the spinal cord and travels to the dorsal root ganglion . The dorsal root ganglia contain the pseudo-unipolar cell bodies of the nerve fibres which travel from the ganglia through the root into the spinal cord.

Detailed explanation-2: -In transverse sections, the gray matter is conventionally divided into dorsal (posterior) lateral and ventral (anterior) “horns.” The neurons of the dorsal horns receive sensory information that enters the spinal cord via the dorsal roots of the spinal nerves.

Detailed explanation-3: -The most important terms of direction for studying spinal cord anatomy are ventral (which means “towards the stomach") and dorsal (which means “towards the back"). Note that in human anatomy, the ventral side of the spinal cord corresponds to the anterior side, and the dorsal side corresponds to the posterior side.
