- adj. Directed away from a central organ or section.
- adj. Carrying impulses from the central nervous system to an effector.
- n. An efferent organ or body part, such as a blood vessel.
Century Dictionary and Cyclopedia
- Conveying outward or away; deferent: as, the efferent nerves, which convey a nervous impulse from the ganglionic center outward to the muscles or other active tissue. In the system of blood-vessels the arteries are the efferent vessels, conveying blood from the heart to all parts of the body, while the veins are the afferent vessels, bringing blood to the heart. In any gland or glandular system the vessel which takes up and carries off a secretion is efferent.
- n. In anatomy and physiology, a vessel or nerve which conveys outward.
- n. A river flowing from and bearing away the waters of a lake.
GNU Webster's 1913

“The fibres which come ultimately from the ventral aspect of the spinal marrow, are those which carry an influence outwards, and produce a contraction in the muscles, and are therefore called efferent or motor.”
“Whatever the specifics, they wrote, the important thing is that the stimulation affected only “a few cubic millimeters of neural tissue,” which means that “the depression probably resulted from the stimulation of afferent, efferent, or passing fibers within the substantia nigra or from the inhibition of those fibers.””
“Motor neurons make up the efferent neurons of both the somatic and autonomic nervous systems.”
“The PNS contains two forms of nerves: afferent nerves, which relay sensory information to the CNS, and efferent nerves, which relay motor commands from the CNS to various muscles and glands.”
“The second efferent system is the autonomic nervous system, which carries motor information to smooth muscles, cardiac muscle, and various glands.”
“Her stances were aesthetic and efferent, the former being reading for emotional/artistic reasons and the latter for informational reasons.”
“Another thought experiment (Kirk 1974b) involves a team of micro-Lilliputians who invade Gulliver™s head, disconnect his afferent and efferent nerves, monitor the inputs from his afferent nerves, and send outputs down his efferent nerves to produce behavior indistinguishable from what it would have been originally.”
“Human gustatory representations are points in a four-dimensional state space, with each dimension coding for activity rates generated by gustatory stimuli in each type of taste receptor (sweet, salty, sour, bitter) and their segregated efferent pathways.”
“Each dimension corresponds to activity rates in one of three classes of photoreceptors present in the human retina and their efferent paths: the red-green opponent pathway, yellow-blue opponent pathway, and black-white (contrast) opponent pathway.”
“The boat's central director-essentially a computer whose input came from the instruments and whose efferent impulses went directly to the controls-performed the basic operations.”
