Testing Spinal cord and Nerves (Part D)

The video tutorial explains the roles of motor and sensory neurons in the dorsal and ventral ramus, highlighting that both are mixed nerves. It discusses how the ventral ramus directly innervates intercostal muscles. The tutorial also covers the effects of dorsal root injury, which affects sensory neurons from the back and anterior lateral body wall, while motor functions remain unaffected due to the ventral root's role.

What does the dorsal root bring in from the back?

How are the motor neurons affected in the ventral route?
