One thing to be mindful of is that while all browsers support the IFRAME element, there is still limited support for some of the HTML5 features. 1  Using overflow to turn off scrolling is not reliable. If you don't want scrollbars on your iframes, you should continue to use the scrolling attribute.
Sigmoid colon, a terminal section of the large intestine that connects the descending colon to the rectum; its function is to store fecal wastes until they are ready to leave the body. The sigmoid colon derives its name from the fact that it is curved in the form of an S (Greek sigma: Ï). Its size depends upon the amount of waste material in it, but when contracted its diameter is only about one inch (2.5 centimetres).
There are two types of sigmoidoscopy: flexible sigmoidoscopy, which uses a flexible endoscope, and rigid sigmoidoscopy, which uses a rigid device. Flexible sigmoidoscopy is generally the preferred procedure. A sigmoidoscopy is similar to, but not the same as, a colonoscopy.A sigmoidoscopy only examines up to the sigmoid, the most distal part of the colon, while colonoscopy examines the whole large bowel.lexible sigmoidoscopy enables the physician to look at the inside of the large intestine from the rectum through the last part of the colon, called the sigmoid. Physicians may use the procedure to find the cause of diarrhea, abdominal pain, or constipation.
