What are the parts of a Seton implant?
A Seton implant typically consists of a medical thread or tube that is placed through a fistula tract to help drain fluids from an abscess or infection. It may include a silicone rubber tube, silk thread, or other material that remains in place for a period of time to allow proper healing of the fistula.
What is the correct direction of aqueous humor flow?
The flow of the aqueous humor flows in the following manner: 1) Ciliary body --> Posterior Chamber 2) Posterior Chamber --> Anterior Chamber 3) Anterior chamber --> Canal of Schlemm Aqueous humour is produced behind the iris by the ciliary body. It flows through the pupil and drains away at the angle between the cornea and iris (the drainage angle). Within the drainage angle, the aqueous humour passes through a porous tissue - the trabecular meshwork - into a collector channel (Schlemm's canal), which empties into veins under the conjunctiva and thus back into the bloodstream. Most of the aqueous humour leaves the eye through the trabecular meshwork. This is called the conventional outflow pathway. There is however another "pathway" if you wish; some aqueous humour also leaves the eye through the ciliary body. This is called the uveo-scleral or non-conventional outflow pathway.
What is measured using the Saffir-Simpson scale?
The Saffir-Simpson Scale is an estimate of the power of hurricanes. Their Categories are Category 1, Category 2, Category 3, Category 4, and Category 5. All of them are destructive, especially Category 3 through 5.
What is primary ciliary dyskinesia?
about 25% of people with situs inversus have an underlying condition called primary ciliary dyskinesia (PCD). PCD, also known as Kartagener's syndrome, is characterized as situs inversus, chronic sinus infections, increased mucous secretions from the lung Primary Ciliary Dyskinesia is a fairly rare lung disorder in which the cilia, or tiny hair-like structures that move mucus through the airways of the lung, do not move or are abnormal. As of this writing no cure exists for PCD.
What category does the harmonium belong to?
The harmonium belongs to the keyboard instrument category. It is a type of reed organ that generates sound by air being blown through reeds by foot-operated bellows.
Can blood be taken from an arm with a fistula?
Yes. I get blood taken out of my arm and put back in through the fistula for "Dialysis".
What structure surrounding the lens that connects the choroid and it alters the shape of the lens?
The ciliary body, which consists of ciliary muscles and ciliary processes, is the structure that surrounds the lens and connects to the choroid. The ciliary body controls the shape of the lens through the action of the ciliary muscles, which can adjust the thickness of the lens to allow for focusing on objects at different distances.
What is the purpose of an AV fistula?
The surgical creation of an AV fistula provides a long-lasting site through which blood can be removed and returned during hemodialysis.
Protrusion of the urinary bladder through the vaginal wall is called what?
Vesicovaginal fistula
Why shouldn't you take a blood pressure on an arm with a shunt?
An artificial shunt for hemodialysis, either a fistula (direct artery to vein connection) or a graft (artery to vein connection through Goretex tubing), can be on the arm, or preferably on the forearm for a fistula. A fistula, and even less so a Goretex, will not burst because of applying pressure through a sphygmomanometer (which was the original answer posted here). There is a slight risk of causing a thrombosis of the venous side of the fistula, particularly if there is already a venous stenosis.
What is the structure between the choroid and the iris that anchors the lens in place?
The ciliary body is a specialized structure which anchors the iris with the choroid. It makes aqueous humor and anchors the lens via the zonules, through which it modulates lens changes.The ciliary body is a specialized structure which anchors the iris with the choroid.

What is the function of the ciliary body?
The ciliary body plays a crucial role in the eye by producing aqueous humor, which helps maintain eye pressure and nourish the surrounding tissues. It also controls the shape and thickness of the lens to facilitate focusing on objects at various distances through a process called accommodation.
How is an arteriovenous fistula diagnosed?
Using a stethoscope, a physician can detect the sound of a pulse in the affected vein (bruit). The sound is a distinctive to-and-fro sound. Dye into the blood can be tracked by x ray to confirm the presence of a fistula.
What can you observe through a rumen fistula?
A rumen fistula is a surgically created entry to the rumen in the left flank of the ruminant, typically permanent and with a rubber or similar material device (a 'cannula') fitted to close it between times of use. It enables the rumen contents to be accessed, and the rumen wall to be viewed and biopsied. Surgically modified ruminants such as these are only found on research farms, where they are used to study rumen function. Looking in through the fistula, you can see the rumen contents and the rumen wall.
When looking at near objects the ciliary mascles are relaxed or contracted?
When looking at near objects, the ciliary muscles are contracted. This contraction causes the lens of the eye to become more rounded, enabling the eye to focus on close-up objects through a process known as accommodation.
Gastrointestinal fistula?
DefinitionA gastrointestinal fistula is an abnormal opening that allows the contents of the stomach or intestines to leak.If it leaks through to a part of the intestines, it is called an entero-enteral fistula.If it leaks to through to the skin, it is called an enterocutaneous fistula.Alternative NamesEntero-enteral fistula; Enterocutaneous fistula; Fistula - gastrointestinalCauses, incidence, and risk factorsMost gastrointestinal fistulas occur after surgery. Other causes include:Gastrointestinal obstructionInflammatory processes, such as infection or inflammatory bowel disease (most often Crohn's disease)Radiation to the abdomen (most often given as part of cancer treatment)Trauma, especially penetrating wounds such as those due to a stabbing or gunshotSymptomsDepending on the part of the intestines that are leaking, gastrointestinal fistulas may cause diarrhea, malabsorption of nutrients, and dehydration.Entero-enteral fistulas may have no symptoms.Enterocutaneous fistulas cause leakage of intestinal contents through an opening in the skin.Signs and testsBarium swallow(to identify a gastrointestinal fistula)Barium enema(to identify a fistula involving the colon)CT scan of the abdomen (to identify fistulas between loops of the intestines or an area of infection, called an abscess, associated with the fistula)Fistulogram (involves injecting contrast dye into the opening of the skin of an enterocutaneous fistula and then taking x-rays)TreatmentSome fistulas close on their own after a few weeks to months. Depending on the situation, some people may need to receive nutrition through a vein while the fistula heals.In some cases where the fistula is not healing, surgery is necessary to remove the fistula and part of the intestines.Expectations (prognosis)How well a patient does depends on their overall health and the cause and severity of the fistula. In otherwise healthy people, the outlook is excellent.ComplicationsFistulas may result in malnutrition and dehydration, depending on their location in the intestine. They may also be a source of skin problems and infection.Calling your health care providerCall your health care provider if you have a significant change in bowel habits, especially severe diarrhea. Also call if you have any leakage of fluid from an opening on the abdomen or near the anus, especially if you have recently had abdominal surgery.ReferencesStenson WF. Inflammatory bowel disease.

What immediate health hazard does esophageal atresia pose?
normal eating or drinking can be dangerous because food and fluids have a direct route through the fistula into the lungs.
