Orad

The sutures of four septa are exposed; the most orad of these can be traced with a fair degree of accuracy throughout almost its entire course.

The frequency of segmenting contractions is higher in the descending and sigmoid colon than in more orad areas.

The endoscope is advanced to its most orad (toward the mouth) limit and then slowly withdrawn so that the mucosa can be thoroughly examined.

The most common symptom of GERD is heartburn, which is described as substernal burning that moves orad from the xiphoid.

Beginning 8 to 10 sec prior to egestion, the pellet is moved orad by esophageal antiperistalsis.

This is due to the UES moving completely off the sensor as it moves orad with the swallow.
