Spicules, or needlelike structures, of lime embedded in the polyp body provide a firm but flexible support. |
|
Hydroids have a polyp or medusa form or they alternate generations of each phase. |
|
|
The stony corals have employed a different tactic: each polyp secretes a cup-shaped skeleton around itself forming a hard outer covering. |
|
Corallimorpharia are well known to aquarists because of their striking forms and colors, the latter often due to symbiotic zooxanthellae within the tissues of the polyp. |
|
The vet surgically opens up the bulla through the side of the neck, scrapes it clean and dislodges the root of the polyp. |
|
We finally had the surgery done months later, and they found no polyp, but the bulla was so infected it was causing all the same symptoms. |
|
Key points include access to colonoscopy, procedure times and polyp detection rate. |
|
The polyp is not much more than a millimetre across, but each is seen to include a ring of tentacles inwardly coiled in a retracted position. |
|
A single coral polyp may be as large as a dinner plate or smaller than the head of a pin. |
|
Some polyps can become cancerous, although early detection and removal of the polyp may prevent this. |
|
The most serious colorectal polyp is the adenoma, a small benign tumor growing to about 2 cm in size. |
|
The larger the polyp, the greater the probability that the polyp will have undergone malignant change and contains cancer. |
|
Corticosteroids have been shown to decrease polyp size and nasal obstruction, but there is no demonstrated effect on sinusitis. |
|
However, factors such as polyp size and histopathology, and patient age must be incorporated into the decision for polypectomy. |
|
A larva metamorphoses into a small polyp termed the scyphistoma. |
|
Although most of the life of Obelia is spent in the sessile polyp form, medusa buds produced within reproductive polyps called gonangia escape into the water column. |
|
The difference between most hydrozoans and most scyphozoans is that in hydrozoans, the polyp stage usually predominates, with the medusa small or sometimes absent. |
|
Biopsies of the polyp and random colonic and ileal mucosa were performed. |
|
The colorful coral colonies that attract visitors to the Great Barrier Reef live atop a limestone scaffolding built from the calcium carbonate secretions of each tiny coral, or polyp. |
|
These red lesions have also been decribed as having the appearance of a polyp or a red bubble, whose contents are very rich in vessels and which explains this colour. |
|
All living corals and sea anemones possess tentacle-bearing polyps, but because polyp tissue is soft and watery and devoid of means for calcification, it has never been found fossilized. |
|
What I usually noticed for a nasopharyngeal polyp was an odd clicking or snorting, or sometimes the kitten would seem to be gulping or gagging oddly. |
|
|
Women found to have asymptomatic polyps on ultrasound should be triaged for intervention according to size of the polyp, age, and other risk factors. |
|
These lesions may represent replacement of mesothelium by an endometrial epithelium or endometrial polyp formation. |
|
A right nasal polyp arising from the septum was observed under the rhinoscope. |
|
Remove the polyp and you eliminate the source of the cancer. |
|
Some foliaceous corals are unifacial, the polyp mouths being confined to one surface. |
|
A differential diagnosis of fungiform papilloma, inverting papilloma, and angiomatous polyp was considered. |
|
He underwent uvulopalatopharyngoplasty and tonsillectomy and a nasal surgery with ethmoid polyp resection. |
|
The c½nosarc is actually a prolongation of the oral and aboral epithelia which join up to delimit a space corresponding to the prolongation of the c½lenteron of each polyp, the c½nosarcal space. |
|
If a person sneezed out a polyp they were advised to swallow it. |
|
A few omit the planula, polyp and ephyra phases and produce new medusae directly from eggs. |
|
After a growth interval, the polyp begins reproducing asexually by budding and, in the Scyphozoa, is called a segmenting polyp, or a scyphistoma. |
|
Histopathologically, the polyp demonstrated long, tubular glands lined with ciliated respiratory epithelium. |
|
The nasal polyp and sinusitis tissues were obtained from the ethmoid sinus in the 64 patients. |
|
The sum of the right and left nasal polyp score provided the total bilateral polyp grade. |
|
Occasionally the laparoscopist will perform a colotomy for a very large polyp that can't be removed with the colonoscope alone. |
|
The patient's mother has Carney syndrome, with lentigines, cardiac myxoma, fibroadenoma of the breast, and a fibroepithelial polyp of the external auditory canal. |
|
The left vocal fold appeared to be normal, but its mucosal wave could not be appreciated because the view was blocked by the polyp during phonation. |
|
To the best of our knowledge, the occurrence of a nasal polyp associated with rhinolithiasis has not been previously reported in the English-language literature. |
|
The goal was to examine whether eicosapentaenoic acid supplementation reduced polyp burden in the setting of FAP, as assessed by blinded outside endoscopists. |
|
For protection, they build hard, cup-shaped houses called corallites around their soft bodies.The new polyp remains attached to its parent and builds its own stony corallite. |
|
|
Gilbertsen reported on a long-term follow-up of rigid proctosigmoidoscopies of 21,140 adenomatous polyp patients attending a cancer detection center. |
|
Hydra never goes through a medusoid stage, and spends its entire life as a polyp. |
|
A young planula settles down as a sedentary polyp, which can sprout more polyps, sometimes for several years. |
|
Some polyps can asexually produce a creeping frustule larval form, which then develops into another polyp. |
