Perla are oval, and each of them attached to a filiform pedicle not thicker than a hair, and seven or eight times as long as the egg.
I have met with a remarkable instance, in which pedunculated eggs seem to draw nutriment from the mother, which brings the pedicle still near to the nature of the umbilical chord.
Eggs similarly furnished with a pedicle are also laid by other insects; but as most of these have been before alluded to, it is not necessary to describe them here[172].
I call the pulley is merely an upper sinus of the large orifice that receives the pedicle of the abdomen.
With regard to the articulation of the pedicle itself with the lower orifice of the trunk, it appears simply suspended, with little or no inosculation.
When there are symptoms of torsion of the pedicle of the tumor, infection, incarceration in the pelvis, involvement of the uterine broad ligament, or overdistention of the belly, the tumor must be removed immediately.
But the long stalk orpedicle of the allantois remains, and forms with its upper part the middle vesico-umbilical ligament, a rudimentary organ that goes in the shape of a solid string from the vertex of the bladder to the navel.
The lowest part of the allantoic pedicle (or the "urachus") remains hollow, and forms the bladder.
The bladder originates from the hindmost and lowest part of the allantoic pedicle (urachus), which enlarges in spindle shape before the entry into the cloaca.
The incision was longer than that now usually made, and the ends of the pedicleligature were left hanging from the lower angle of the wound.
But the pedicle itself was dropped back into the abdomen.
Smooth Anatifa, as seen from the other side, the pedicle dry and contracted.
The siphuncular pedicle of the visceral hump broken off short.
No structure comparable to this siphuncular pedicle is known in any other Mollusca.
Spirula, is that the series of deserted air-chambers is traversed by a cord-like pedicle extending from the centro-dorsal area of the visceral hump to the smallest and first-formed chamber of the series.
It forms the connecting link between the foetus and the maternal placenta, since it conducts the nutritive vessels from the body of the foetus to the placenta; it comprises, besides, the pedicle of the allantois and the yelk-sac.
Finally, there is a special significance in the fact, established by Selenka in 1890, that the anthropoid apes share with man the peculiar structure of the discoid placenta, the decidua reflexa, and the pedicle of the allantois.
In favourable cases the pedicle is now brought easily into view.
Further to avoid this danger, the pedicle may be transfixed by one or two needles above the clamp.
When the pedicle is excessively broad and stout, it should be transfixed by strong needles and double threads in various places, and thus tied in several portions.
Absence of thepedicle greatly adds to the danger in any given case.
The pedicle is brought to the surface, and in every case where it is possible is secured outside the wound.
This gives a free drain for pus, but theoretically the sloughing pedicle might be expected to set up peritonitis; (2.
We will suppose at present that none exist in this typical case, and that the pedicle is found of a satisfactory size and shape.
This is quite a suitable case for the use of the clamp, the principle involved in the use of which is, that the pedicle should be brought quite out of the abdomen through the wound and secured on the surface.
In such a condition it is impossible to save the ovary without risk, and also inadvisable to attempt the inclusion of the round ligament in the pedicle containing the ovarian vessels.
The silk used to secure an ovarian pedicle may, in very favourable circumstances, disappear in twelve months, but the knots require nearly double that time.
Doran, who has written an excellent review of this matter, ascribes the intraperitoneal method of dealing with the pedicle to the systematic advocacy of Tyler Smith.
When the pedicle is short and broad the tumour should be shelled out of its capsule, and any obvious blood-vessel is easily secured with forceps and ligatured with silk.
Here it serves to manipulate the loop over the growth, and holds it close to the root of the pedicle while the snare is pulled home.
An ovarian cyst with a twisted pediclehas been found in a fœtus at birth (Otto von Franque).
When the constituents of the pedicle are unobscured by adhesions, the round ligament of the uterus is easily seen and need not be included in the ligature.
It has happened, in the course of removing very adherent ovaries and tubes from the floor of the pelvis, that in transfixing the pedicle a coil of ileum has also been transfixed with the needle and tied to the stump.
This crescentic flap is then dissected up from the deeper tissues all round, except for a smallpedicle at its centre (Fig.
After the pedicle has been safely ligatured and the blood removed, the abdominal incision is sutured as described on p.
Slight traction may be made upon it by means of forceps, and the pedicle severed with scissors; no hæmorrhage takes place, owing to the retraction of the stump.
Having satisfied himself that the pedicle is secure, the surgeon examines the opposite ovary, and if obviously diseased it should be removed.
When at their full growth, their pedicle is of a finger's length, larger at top than at bottom, and becomes insensibly slenderer in proportion as it is nearer the earth.
The difficulty of meeting with the passage in the pedicle of the egg, can only be compensated by the infinite number of spermatic worms.
All the worms which find not this passage through the pedicle into the egg will perish, and that one which alone has traced its way will arrive at its transformation.
It is a million to one that any particular spermatic worm will meet with the pedicle of the egg, and therefore what at first appears a profusion is highly necessary.
The ciliated band of the left side of the velar area is indicated by a line extending from v to v; the foot f is seen between the pharynx ph and the pedicle of invagination pi.
The rectal peduncle or pedicleof invagination; its attachment to the ectoderm is coincident with the hindmost extremity of the elongated blastopore of fig.
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.
Between the mouth and the attachment of the enteric pedicle is placed the foot (f), which becomes ciliated.
On the dorsal side of the enteric pedicle there appears a saddle-shaped patch of epiblast cells bounding the sides of a groove (shs).
In Pisidium the intestine is formed from the original pedicle of invagination, which remains permanently attached to the epiblast.
The allantois is as before, for the sake of simplicity, omitted; its pedicle would of course lie by the side of ys in the somatic stalk marked by the usual dotted shading.
The pedicle (pd) retains its original attachment to the skull.
The embryo was enveloped in an amnion reflected over the stalk of the yolk-sack, which was attached by a filamentary pedicle to near the end of the ileum.
Its upper end exhibits a tendency to divide into two processes, corresponding with the pedicle and otic processes of the Amphibia.
The broad ligaments and Fallopian tubes were ligated on either side, the tumor turned out, the thick, heavy pedicle transfixed and ligated, and the enormous growth cut away.
The attachment was effected by means of a pedicle 33 cm.
One of these women, a secundipara, had gone two weeks over time, and had a large ovarian cyst, the pedicle of which had become twisted, the fluid in the cyst being sanguineous.
As the furrow deepens the distal end of the toe becomes ovoid, and soon an appearance as of a marble attached to the toe by a fibrous pedicle presents itself.
It had no pedicle and was fixed, showing unequal consistency.
The pedicle was rather small and was tied in the usual way, and the tumor was removed.
We now know from Selenka that the much-discussed ventral pedicle is merely the pedicle of the allantois, combined with the pedicle of the amnion and the rudimentary pedicle of the yelk-sac.
The embryo hangs by the umbilical cord, which encloses the pedicle of the allantois (al).
The embryo (a month old) hangs in the middle of the amniotic cavity by the ventral pedicle or umbilical cord, which connects it with the placenta (above).
This pedicle is the vitelline duct, and is separated from the body at the closing of the navel.
The section shews the constriction of the pedicle which attaches the posterior nerve-rudiments to the spinal cord.
D a, and itspedicle of attachment to the spinal cord is thinner.
And clustering around the base of the pedicle are the sexual flowers.
The question of the pedicle comes up again when he simplifies some of Parker's results as to the development of the Columella auris in the Frog.
Your suprahyomandibular is nothing but the pedicle of the suspensorium over again.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "pedicle" in a variety of sentences. We hope that you will now be able to make sentences using this word.
