Thus, there are six openings from the pharynx; the oesophagus being the direct continuation from it to the stomach.
In its lower part are two openings; the trachea, or windpipe, in front, and the oesophagus behind.
The lining of the mouth and oesophagus is not well adapted for absorption.
The throat is a double highway, as it were, through which the air we breathe traverses the larynx on its way to the lungs, and through which the food we swallow reaches the oesophagus on its passage to the stomach.
Showing the relative position of the heart and its great vessels, the oesophagus and trachea.
The vomiting in these instances is usually attributed to the presence of aphthae in the oesophagus and stomach, and the diarrhoea to their presence in the intestines.
An abnormal distension of a portion of the oesophagus or of the entire tube, whether general, annular, or pouched.
Laryngoscopic inspection and digital exploration are sufficient when the entrance into the oesophagus is involved.
Gastrostomy, too, should hold out some hope of rescue, no matter what portion of the oesophagus be dilated.
In some instances food is regurgitated from theoesophagus after its retention for a day or even longer.
Atrophy of the oesophagus may ensue below the stricture if at all tight, and the mucous membrane becomes thrown into longitudinal folds.
The diagnosis between hemorrhage from the oesophagus and that from the stomach must be based upon the clinical history.
It may be due to mechanical restraint from external adhesions of theoesophagus to intrathoracic tumors (Finny[25]).
Perforation of the oesophagus ensues in some instances, and death results in consequence of the injuries sustained by perioesophageal structures by the escape of the contents of the oesophagus.
The duration of the affection depends upon the surroundings of the patient, his amenability to treatment, and the existence or absence of disease in the oesophagus or elsewhere.
Though denied by some authorities, syphilitic disease of the oesophagus is an undoubted cause of stricture.
Sometimes the diverticulum drags the oesophagus out of position and forms a sort of blind pouch in the direct line of its axis, so that it becomes filled with food which fails to reach the stomach.
The oesophagus of the female is not in any way remarkable.
Tetrao urophasianus, inflation of the oesophagus in the male, ii.
It produces a hot burning sensation in the fauces and oesophagus in the act of swallowing, severe burning pain in the stomach, and in most instances immediate vomiting.
The mucous membrane of the mouth, fauces, and oesophagus is softened and of a whitish or bluish-grey color.
The burning is followed by retching and vomiting of a dark colored liquid with shreds of mucus, and portions of the mucous membrane of the oesophagus or stomach.
The oesophagus was completely dissolved at its junction with the stomach, and there was an aperture in the anterior wall of that organ such as might have been caused by oil of vitriol.
The oesophagus may be the seat of a diverticulum, or blind pouch, usually situated in its lower half, which in most instances is probably partly acquired and partly congenital; a local weakness succumbing to pressure.
The oesophagusis the seat of inflammation but seldom.
Traction diverticula of the oesophagus not uncommonly occur as sequels to suppurative inflammation of cervical lymphatic glands.
In the stomach and oesophagus the scirrhous form is most common, the soft encephaloid form coming next.
This leads to a muscular oesophagus with a triradiate lumen, which acts as a sucking pump and ends in a funnel-valve projecting into the stomach.
A cerebral ganglion rests on the oesophagus and supplies the cephalic cilia and hairs; it is continued some way back as two dorsal nerve trunks.
This bilobed sac becomes entirely the liver in the adult; the intestine and stomach are formed from the pedicle of invagination, whilst the pharynx, oesophagus and crop form from the stomodaeal invagination ph.
The oesophagus expands into a curious gizzard, which is armed internally with large horny processes, some broad and thick, others spinous, fitted to act as crushing instruments.
So has the acrembolic pharynx of Chaetopods, if we consider the organ as terminating at that point where the jaws are placed and the oesophagus commences.
This migration produces a corresponding increase in the length of the oesophagus (Fig.
Frequently this slight dilatation is scarcely differentiated from the oesophagus at the cephalic and from the small intestine at the caudal end.
The two dorsal aortic roots are seen to unite to form the main aorta, which descends between the layers of the dorsal mesentery, sending branches to the dorsal margin of oesophagus and stomach.
A distinct digestive segment may even be entirely wanting, owing to its failure to differentiate from the oesophaguson the one hand and from the endgut on the other.
Superficially the external longitudinal muscular fibers of the oesophagus pass continuously and without demarcation into the superficial gastric muscular layer.
With the development of the heart the primitive foregut becomes divided into pharynx and post-pharyngeal segment (oesophagus and stomach).
The oesophagus or gullet, usually forming a short, wide tube, leads into the glandular, more or less dilated stomach.
The main vagus, after this branching, passes behind the heart to the oesophagus and along it to the stomach.
There is a wideoesophagus passing into a U-shaped stomach (st.
Pharyux" is here used in a wider sense than in the true vertebrata; it reaches back close to the liver, and is therefore equivalent to pharynx + oesophagus + a portion or all of the stomach.
The passage down theoesophagus is called deglutition.
The oesophagusis less distinct, and passes gradually, so far as external appearances go, into the bag-like stomach, which is much less inflated and transverse than that of the rabbit.
Cut through the oesophagus and rectum, and remove alimentary canal from body; cut open and wash out the intestine, and examine spiral valve.
Air is at the same time swallowed, and the oesophagus thus becomes much swollen; and this probably acts as a resonator, not only with the hoopoe, but with pigeons and other birds.
Tetrao urophasianus, inflation of theoesophagus in the male.
The beak in one bird which I possessed was almost completely buried when the oesophagus was fully expanded.
The diameter of the upper part of the oesophagus is immense, even close up to the head.
When the oesophagus of a dead bird was inflated, it was seen to be larger than in other breeds, and not so distinctly separated from the crop.
The Pouter inflates both its true crop and oesophagus; the Turbit inflates in a much less degree the oesophagus alone.
The size and form of theoesophagus and crop, and their capacity for inflation, differ immensely.
Feathers divergent along the front of the neck and breast; beak very short, vertically rather thick; oesophagussomewhat enlarged.
Oesophagus of great size, barely separated from the crop, often inflated.
In the case of the pouter we may suppose that some bird inflated its crop a little more than other pigeons, as is now the case in a slight degree with the oesophagus of the turbit.
It approaches in general form the Dutch Pouter, but the inflated oesophagus assumes a spherical form, as if the pigeon had swallowed a large orange, which had stuck close under the beak.
A portion of the oesophagus cut open, showing the internal folds of the mucous membrane.
On each side of the termination of the oesophagus there is a muscular ridge projecting, so that the two together form a sort of groove or channel, which opens almost equally into the second and third cavities (b and c).
The cuticular membrane of the oesophagus terminates at the orifice of the stomach.
That nearest the orifice of the oesophagus is the broadest, and appears to act occasionally as a valve, so that the part beyond may be considered as an appendage similar to that of the peccary and the hog.
Her color and strength were good, the heart was perfectly strong, the anæmic murmur was gone, and the oesophagus was so much less irritable that it was possible to begin dilatation of the stricture.
No drugs were given, electricity was not used, and extra food was omitted, as the irritability of the oesophagus made her unwilling to attempt the exertion and annoyance of frequent feeding.
It is a remarkable fact, not yet understood, that in certain Enchytraeidae and Lumbriculidae the spermathecae open into the oesophagus as well as on to the exterior.
There is no armature, and no glands, and the whole tract can only be divided into an oesophagus and an intestine.
The oesophagus is often furnished with glandular diverticula, the "glands of Morren," which are often of complex structure through the folding of their walls.
The mouth opens into an oesophagus which passes into an intestine; this opens by a ventral anus situated a little in front of the posterior end.
A buccal cavity, a pharynx, an oesophagusand an intestine are always distinguishable.
On the other hand, additional longitudinal trunks are sometimes developed, the chief one of which is a supra-intestinal vessel lying below the dorsal vessel and closely adherent to the walls of the oesophagus in which region it appears.
The oesophagus is provided often with caeca which in Syllids and Hesionidae have been found to contain air, and possibly therefore perform the function of the fish's air-bladder.
Van Beneden and Julin[416] assumed that in the ancestors of Vertebrates the oesophagus shifted forward between the still unconnected lobes of the brain to open on the hæmal surface.
The cerebral ganglion was formed by the ends of the nerve-cord growing up round the oesophagus and fusing with the paired "sense-plates" which develop from the ectoderm of the head.
Other organs occur in most of the classes--the oesophagus and the lungs.
The lumen of this part appears to be all but obliterated in the stages immediately before hatching, giving rise for a short period to a solid oesophagus like that of Elasmobranchii and Teleostei[548].
Characteristic of the oesophagus is the junction of the two sympathetic nerves on its dorsal wall (fig.
It tapers both in front and behind, and is narrowest in the middle, and is marked off sharply both from the oesophagus in front and the rectum behind, and is distinguished from both of these by its somewhat pinker hue.
The limits of the solid part of the oesophagus are very satisfactorily shewn in longitudinal and vertical sections.
The oesophagusis vertically oval in front, but more nearly circular behind.
A curious point which has turned up in the course of my investigations is the fact that for a considerable period of embryonic life a part of the oesophagus remains quite solid and without a lumen.
The region of the oesophagus following the pharynx is not separated from the stomach, unless a glandular posterior region (vide description of adult) be regarded as the stomach, a non-glandular anterior region forming the oesophagus.
In the succeeding stages the solid part of the oesophagus immediately adjoining the stomach is carried farther back relatively to the heart and overlies the front end of the liver.
The part of the oesophagus to undergo this peculiar change is that which overlies the heart, and extends from the front end of the stomach to the branchial region.
Behind the pharynx there follows a narrowoesophagus (fig.
Unless there is a very decided projection of the foreign body on the right, the left side of the neck should be chosen, as the oesophagus normally lies rather on the left of the middle line.
To cut upon the flaccid empty oesophagus in the living body would be an extremely difficult and dangerous operation, from the manner in which it lies concealed behind the larynx, and in close contact with the great vessels.
The pneumogastric, phrenic, and cardiac nerves lie parallel to its course; the oesophagus and thoracic duct lie behind it, and to its inner side.
No special sutures for the wound in the oesophagusare required, nor is it advisable too closely to sew up the external wound.
When instruments are being passed into the oesophagus through the nasal fossa, they are not so likely to encounter the rima glottidis below the epiglottis, 9, as when they are being passed into the oesophagus by the mouth.
Day and night Ulysses' barks now bounded over the blue waves.
Mars' principal votaries were therefore the Roman soldiers and youths, whose exercising ground was called, in his honor, the Campus Martius, or Field of Mars.
Here the vessel splits, and each half returns along the lateral edge of the proboscis; they reunite around the oesophagus and form a single ventral vessel, which lies above the ventral nerve-cord.
Thus there is a lateral nerve near each edge of the proboscis which unites with its fellow dorsally above the oesophagus at the tip of the proboscis, and ventrally beneath the oesophagus, where they fuse to form the ventral nerve-cord.
They are little ivory prongs, with the points turned inwards, analogous to the thorns of the oesophagus in the tortoise, and serve the lizard solely to retain and bruise his prey.
After the oesophagus comes a crop (jabot), very distinctly indicated; then a gizzard with thick coats, in which the food is ground down.
Then it is swallowed, passing through the oesophagus to the stomach.
At the lower end of the oesophagus the digestive tube becomes enlarged, and has a shape somewhat like a pear.
After we have chewed the food, we swallow it, and it passes down through the oesophagus into the stomach.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "oesophagus" in a variety of sentences. We hope that you will now be able to make sentences using this word.
