1 Efferent neurons (also called motor neurons) carry signals from the gray matter of the CNS through the nerves of the peripheral nervous system to effector cells. 2  The effector may be smooth, cardiac, or skeletal muscle tissue or glandular tissue. Afferent, Efferent, and Mixed Nerves. 2  Some of the nerves in the body are specialized for carrying information in only one direction, similar to a one-way street. 3  Nerves that carry information from sensory receptors to the central nervous system only are called afferent nerves.
It always takes two visceral efferent neurons to conduct an impulse from the spinal cord (or brain, in some cases) to a muscle or gland: 1  Visceral efferent 1 (also called the preganglionic neuron) is a multipolar neuron that begins in the gray matter of the spinal cord, which is where its cell body is located. This neuron leaves the cord through the ventral root of a spinal nerve, leaves the spinal nerve via a structure called the white ramus, then ends in an autonomic ganglion (either sympathetic or parasympathetic).
