Spinal nerve.....
motor fibers
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).
somatic motor axons
The anterior or ventral roots carry motor or efferent information from motoneurons in the anterior horn to muscles. This is as opposed to the dorsal roots that convey sensory or afferent informaiton from the periphery to the dorsal horns of the spinal cord. This is not to be confused with ventral rami that subserve intrinsic muscles of the back and neck. Therefore if a ventral root is severed or cut there would be a loss on motor function to muscles in the distribution of that root (called a myotome).
dorsal root ganglia..just outside of the spinal cord
The anterior root is composed of nerve fibers responsible for motor activity (i.e. efferent nerve fibers that will stimulate muscles, etc.). I think some of the things it is composed of include:Gamma motor neurons, alpha motor neurons, preganglionic autonomic neurons
