Dorsal and ventral roots are a feature of spinal nerves only. Cranial nerves do not have dorsal and ventral roots.
Spinal Nerves Are Both Sensory and Motor. Spinal nerves are not one or the other.
spinal nerve
Ventral nerves are nerves that emerge from the spinal cord on the ventral side (front) of the body. They carry motor commands from the brain to muscles and organs, controlling movement and functions such as respiration and digestion.
It is where the nerves go and spinal fluid is and protects spinal cord
The spinal nerves that originate from the thoracic portion of the spinal cord don't form plexuses. The word thoracic pertains to the thorax.
Spinal nerves (aka mixed spinal nerves) are formed from the dorsal and ventral roots coming out of the spinal cord.A spinal nerve is made of mixed nerves. They have both sensory and a motor aspect. The roots of sensory fibers are on the dorsal side of the spinal cord.

The ventral rami serves as a form of intercostal nerves, which supply the muscles between the ribs and the skin and muscles of the anterior and lateral trunk.
Each spinal nerve attaches to spinal cord by a ventral (anterior) root and a dorsal (posterior) root.All spinal nerves are mixed nerves (both motor and sensory).
The brachial plexus primarily comprises the ventral rami of spinal nerves C5 to T1, but there are several nerves that are not part of it. Notably, the intercostal nerves, which arise from the thoracic spinal nerves (T1 to T11), and the phrenic nerve, which originates from C3 to C5, are not included in the brachial plexus. Additionally, the cranial nerves, such as the vagus nerve (cranial nerve X), also do not belong to this plexus.
