Efferent fibers are projections of motor neurons that control the gut's motility.

In vertebrates, motor neurons (also called motoneurons) are
efferent neurons that originate in the spinal cord and synapse with muscle
fibers to facilitate muscle contraction and with muscle spindles to modify proprioceptive sensitivity.
The vagus nerve is composed of two kinds of
fibers: 10 - 20 % of
fibers are «
efferents» whereas the remaining 80 - 90 % are «afferents.»
Muscle
fibers produce tensile force in this way in response to pulsed electrical signals sent from the central nervous system (CNS) along
efferent nerves.
Unlike the action potential that travels in a single direction along the
efferent nerve, the propagating MAP travels in both directions along the muscle
fiber from the motor point.
When the central nervous system sends a signal (called neural drive) down the
efferent nerves to the neuromuscular junction, this causes an action potential to propagate along the muscle
fiber, leading to depolarization.
