This circuit of communication from the cell over the afferent nerves to the nerve centers in the brain or spinal cord, and from these centers over the efferent nerves back to the cell or to other cells is called the reflex arc.
In response to this call of distress the command comes back over the efferent nerve filaments: "Withdraw the fingers!
They are, in a word, reflex: to produce them an impulse has travelled up the sensory or afferent nerves to the gray matter of the spinal cord, and has been reflected back along the efferent or motor nerves to the muscles.
The nerve-threads which carry impulses away from the centre to the outer regions of the body are known as efferent nerves, because through them motion is produced as motor nerves.
The efferent ducts are ciliated, and there is a patch of cilia at the point where they communicate with the cavity of each testis.
Each testis communicates by means of an efferent duct with a common collecting duct of its side of the body, which opens on to the exterior by means of a protrusible penis, and to which is sometimes appended a seminal vesicle.
The male ducts are either one pair or two pairs, which open by a common and complicated efferentterminal apparatus furnished with a protrusible penis.
The branchial efferent vessel carrying aerated blood to the auricle, and here interrupting the circlet of gill lamellae.
A nævus is a collection of dilated capillaries, the afferent arterioles and the efferent venules of which often share in the dilatation.
They receive lymph from the deep lymphatics of the lower limb, and some of the efferent vessels from the femoral and superficial inguinal glands.
Modern psychology thus sees in muscles organs of expression for all efferent processes.
It is as if what are sometimes called the associative fibers, both ends of which are in the brain, were dwarfed in comparison with the afferent and efferent fibers that mediate sense and motion.
In all these modes of developing our efferent powers, we conceive that the race comes very close to the individual youth, and that ancestral momenta animate motor neurons and muscles and preside over most of the combinations.
Thus only can we have a true scale of standardised culture values forefferent processes; and from this we can measure the degrees of departure, both in the direction of excess and defect, of each form of work, motor habit; and even play.
It holds singularly aloof from other methods of efferent training and resists coördination with them, and its provisions for other than hand development are slight.
In childhood, before twelve, the efferent patterns should be developed into many more or less indelible habits, and their colors set fast.
The right and left auricles (enlargements of theefferent branchial veins).
From each gill-plume the blood passes by the branchial efferentvessels to the heart, the two auricles being formed by the dilatation of these vessels.
Efferent branchial vein on the free face of the gill-plume.
The ventricle of the heart is a four-cornered body, receiving a dilated branchial efferent vessel (auricle) at each corner (fig.
The auricles, one pair, are contractile expansions of theefferent branchial vessels.
Third, an efferent or conative part through which it gives rise to a characteristic type of conduct.
In this latter function, namely the reflexifacient, all that the receptive organs effect is effected by means of the efferent nerves.
Should the cortex be functioning harmoniously, afferent impulse and efferent reaction stand in due proportion one to the other; but any disturbance of psychical equilibrium--e.
Their yolk-vesicles were distinctly seen; but the main efferent canals were only here and there traceable.
The terminal cells or capsules with their efferent ducts were well seen in several specimens.
The blood is collected from the walls of the gill-sacs by a series of efferentvessels which open into the dorsal aorta.
It is only whereefferent stimuli do not immediately become entirely transmuted into outwardly moving impulses that mental action comes in and an animal feels.
A message along a nerve to a ganglion cell is an afferent impression, from a cell to a muscle or other external end is an efferent impression.
A vast amount of our activities are reflex, and in such action an efferent stimulus follows an afferent promptly and quite mechanically.
Run a seeker from the dorsal aorta to the efferent branchials.
Cut away the heart and oesophagus; run a seeker up the dorsal aorta and cut along it from the ventral side to subclavian and efferent branchial arteries.
Each possesses its own afferent branchial blood-vessel from the ventral aorta, and its own efferentvessel to the dorsal aorta (Fig.
The question therefore of primary importance in endeavouring to determine the nature of the origin of the alimentary canal from its innervation is the determination of the efferent supply to the musculature of its walls.
The three outflows ofefferent nerves belonging to the organic system.
From the gill-lamellae the blood is collected into an efferent or branchial vein (v.
Then adjusted itself to the exact micro-frequency that carried the messages in his efferent nervous system.
Every efferent neuron in his system carried the message full power.
Efferent nerves discharge impressions which can be read.
All of the organs of the Argasid are invaded by the parasites, but they pass from the coelom into the acini of the salivary glands and collect in its efferent canal.
Thus, when one observes the isolated primary gland it appears as though it had efferentducts inserted at the same point.
The efferent ducts form a trunk, which receives a branch from a small accessory lobe, and then unites with its fellow.
A similar conical process with an efferent duct traversing it is very striking in most of the Amphipoda.
From it nerves (efferent nerves) run outwards to the organs of response.
And in it the transmitted stimuli, brought in by the afferent nerves, are modified, through intervention of the co-ordinants, into stimuli carried out by the efferent nerves.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "efferent" in a variety of sentences. We hope that you will now be able to make sentences using this word.
