Polyp Essays

Chitons are a class of mollusc called Polyplacophora, when examined, share the same anatomical features as those of the first molluscs on earth. This means that they are t closely related to the beginning of the mollusc group. These molluscs vary in size but have the same features as a long, oval flat body with a segmented mantle to protect the ventral of the chiton. These organism have learned to create a “suction” affect using their ventral to hold on to rocks so that they do not get washed away

Intraspecific evolution is the evolution that is continually occurring within a species. When a species undergoes this type of evolution they are subject to many evolutionary pressures such as mutation, migration and selection. How the species reacts to these pressures effects their genetic variation, gene flow, chances of survival and all together their growth as a species. Whales are a group of species that have undergone many evolutionary pressures and many species have experienced bottlenecks

Cephalopoda Introduction: Invertebrate animals which belong to mollusks which means “head foot” and characterized by large head and modified feet. This group includes octopuses, squid, cuttlefish and nautiluses. Members of cephalopods are characterized by their ability to quick change their color as well as changing the texture and shape of their bodies as a means of camouflage. Today there are about 800 living marine species of cephalopods which are found in all of the world’s oceans, from the

Home Remedies for Nasal Polyps What Are Nasal Polyps? Nasal polyps are growth on the inside of your nose and where your sinuses open into your nasal cavity. They range in size and affect people differently. Nasal polyps are reoccurring, even after being treated successfully with medication. They are also associated with asthma and severe allergies. The Top Home Remedies for Nasal Polyps While most people would prefer to go to the doctor for help treating their nasal polyps, there are some people

The word Polyp is originally Greek and has undergone Latinization and means Polypous that is many footed.35 The term Polyp mentions to the macroscopic appearance of a pedicled tissue arising from a mucosal surface and projecting into lumen or cavity.26 Hence Nasal polyps are defined as pearly white painless prolapsed pedunculated parts of nasal mucosa.35 PATHOLOGY OF NASAL POLYPS. Macroscopically Polyps have an edematous smooth and shiny appearance with a soft consistency

Asterios Polyp Analysis Asterios Polyp uses color to effectively highlight the changes in Asterios’ viewpoint and mental state. Blue is most commonly used when Asterios is remembering his past, seemingly to demonstrate melancholy, sadness and regret for his past actions. In the beginning of the novel, when Asterios is watching the tapes he filmed while living with Hana, he is very clearly upset that his marriage had disintegrated. But it seems as if he is also feeling a lot of guilt for watching

Colon Polyp Treatment in Los Angeles- Methods of Screening for the Presence of Polyps A polyp is a fleshy growth of cells that develops on the inner lining of the colon or rectum. These are largely asymptomatic (therefore producing no noticeable signs or symptoms), which means that the majority of patients are completely unaware of their presence. Screening is often the only way in which these polyps can be identified and treated. Why Do I need To Be Screened For Colon Polyps? As polyps will normally

I. Introduction of EB problem to be researched The topic of choice is urinary catheters. Many patients have or will have catheters in their hospital stay or in their lifetime. Catheters come in a variety of different types of shapes and tips. A one-way catheter also known as a “straight cath” is a quick way to get urine out of the bladder for clean collection or to just remove urine. The one-way catheter does not have a balloon at the tip, therefore, it does not remain in the patient. The two-way

Asterios Polyp is a very well developed, easily analysed, novel due to the extensive work on inner meanings. One thing that the book translates so well is a sense of character. It does this in various ways that most novels lack the ability to do; such as color, text, and general art. On a given page with word bubble dialogue most readers can pick up the recurrence of text being askewed to particular fonts accordingly to certain people. Less may see that these font style represent them as a person

the management of Sinonasal diseases. Sushruta designed tubular nasal speculum called Netiyantra. Following Sushrutas “Netiyantra” to examine the nose, Pere Dionis described first nasal speculum in 1714. He also tried to explain the origin of nasal polyp by examining nasal polypi. The search to look into the nose and especially into the sinuses continued with Wertheim in 1896 who designed a “conchoscope” to see deeper into the middle meatus. Gustav Killian became more concerned to look further into

habits of 6 month duration was found to have numerous polyps in the colon with colonoscopy. He also had two osteomas on the forehead and several epidermal cysts in the scrotal skin. His brother had a history suggestive of a similar disease. The patient underwent total proctocolectomy and ileal pouch – anal anastomosis. Pathological examination of the resected specimen revealed a moderately differentiated adenocarcinoma in addition to numerous polyps which were villous, tubulo-villous and tubular adenomata

Phylum Cnidarian a. Feeding Cnidarians have only one opening called the gastrovascular cavity. This is where the food enters and the waste leaves. Cnidarians are hunters. They paralyze their prey before putting it in their mouth. To cut, and stick to their prey, Cnidarians use their nematocysts. Their Nematocysts contains toxic chemicals to kill whatever they are hunting, their prey. b. Digestion Digestion begins in the gastrovascualr cavity. This cavity is a digestive chamber. Digestion in this

and a low level of salinity such as the Atlantic estuaries. Additionally they can be found inhabiting rivers that are meso and polyhaline water. Life cycle/reproduction: The C. quinquecirrha has two distinct stages of development, a polyp and medusa stage. In the polyp stage the C. quinquecirrha is free-floating or sessile which means that it cannot move while in the medusa

Illini Bluffs High School  A cnidarian is an animal, therefore classified in the kingdom of Animalia, from the phylum Cnidaria. They are all classified as invertebrate which means they do not have a backbone. At some point in their lives they are a polyp and a medusa. They are all radially symmetric, and can either live in large colonies or on their own. While most Cnidarians live in the water, I have chosen one that lives only in the larval stage underwater. It is called the Velella, also known as

Coral reefs. By: Valentina Sarria. Coral reefs are one of the most diverse and complex habitats. They are one of the most interesting and colorful ecosystems found in the marine environment. They are very unique in many different ways and a crucial support for human life. They play also a very important role in the marine life such as giving shelter and food for millions of species including fishes, crabs, or shrimps. They support 33% of marine fish species. They also have specific and certain

can theoretically forever stay alive. Fertilized eggs of T. dohrnii grow out of polyps that are part of a polyp colony. From these polyps arise jellyfish that are sexually mature in about two weeks. These jellyfish again produce eggs or sperm. Many other jellyfish die after they have secured posterity. But T. dohrnii is different. The jellyfish can, after it has reached sexual maturity, return into the stage of the polyp. It does not matter whether the jellyfish has been a jellyfish for a while or

Peutz-Jeghers Syndrome is described by a Dutch physician named Jan Peutz back in 1921. Jan Peutz noted signs in a Dutch family appearing with intestinal polyps and also had noticed mucocutaneous macules. John McHutchinson, a man who reported signs in the year of 1896, had a case involving a pair of twins that was identical with an ending result leaving one twin that died. An American physician, Harold Jeghers, had published a statement with a definite descriptions of this syndrome. Shortly after

this procedure in patients of Nasal Polyposis in our population and to compare its result with the result of previous study in last 5 years of our population.1 There is better visualization, good outcome and success rate and less recurrence of nasal polyps with endoscopic sinus surgery. In our population most of the cases of Nasal Polyposis are still treated with conventional surgical procedures which have no better outcome and success, more recurrences and complications. If results show good outcome

Natalie Koch Bio 2 Metridium The metridium, which is also known as the plumose anemones, is a sea anemone that is classified under the kingdom Animalia and the phylum Cnidaria. Which is the same phylum as jellyfishes and corals. The metridium is typically found in cooler waters of the Pacific and Atlantic oceans up in the Northern Hemisphere (Wikipedia.com, 2013). They typically collect in deep rock openings, or in deep regions under docks, floats, or pilings (Fretwell, 2013). In some instances

called coral polyps, or corals, create coral reefs. They produce a rock-like substance that forms a hard exoskeleton, or outside skeleton. Millions of polyps doing this over time create huge reefs. Polyps are among the ocean 's most fragile creatures. The slightest touch by an object--like an anchor--can hurt or kill them. Also, the animals grow only in clean tropical water that 's between 68°F and 82°F. A change in the water 's temperature or chemical makeup can be deadly for polyps. Experts say
