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.
Those that carry impulses in the opposite direction, away from the brain and other nerve centers to muscles, are called efferent neurons, motor neurons, or motoneurons. Another type, the interneuron, found in the brain and spinal cord, conducts impulses from afferent to efferent neurons.here are many types of neurons within the nervous system; some transmit afferent nerve impulses to the brain (e.g. those carrying information from the photoreceptors to the visual cortex), or to the spinal cord (e.g. those carrying information from the receptors in the skin to the spinal cord).
