Origin of the Intercostal Nerves
Dorsal and Ventral Rami of the spinal cord
What are the difference between root and rami?
The root comes right off the spinal cord and the rami comes after the dorsal root ganglion. The rami split into dorsal and ventral rami and are mixed (sensory and motor).
Are the spinal roots mixed?
no! The dorsal spinal root is purely sensory and the ventral is motor.

The erector spinae muscle group
What does the Ventral rami innervate?
The external and internal intercostal muscles
