What are the two main branch sod spinal nerves?
what do they carry

Dorsal and ventral branches (mixed motor and sensory fibers)


What areas do the ventral and dorsal motor branches of the spinal nerves supply motor innervation?

Dorsal: muscles dorsal to the transverse processes, sensory innervation not exactly the same


What spinal nerve branches supply sensation from the skin of the abdominal wall and back
