peristaltic wave

It came in slow, peristaltic waves, and she had a dismaying idea that this was only the beginning.

During vomiting, anti peristaltic waves travel in the reverse direction.

The chamber is also lined with muscles that contract and expand regularly in peristaltic waves.

The anti peristaltic waves may begin in the ileum and travel backwards at a rate of 2-3 cm/second.

The viral nchoo agents effected the contraction in peristaltic waves.

Measurements are taken between peristaltic waves.

Any episodes of failed peristalsis were excluded from further analysis of the peristaltic wave characteristics.

This action potential is transmitted to other smooth muscle cells via gap junctions, creating a peristaltic wave.

First, there is a primary peristaltic wave, which occurs when the bolus enters the esophagus during swallowing.

He could see it, he realized: his own aura running down his right arm and across the back of his hand in slow, peristaltic waves.

There are often palpable (or even visible) peristaltic waves due to the stomach trying to force its contents past the narrowed pyloric outlet.

The primary peristaltic wave forces the bolus down the esophagus and into the stomach in a wave lasting about 8-9 seconds.

Once past the stomach a typical peristaltic wave will only last for a few seconds, travelling at only a few centimeters per second.

The Law of the Gut states "The peristaltic wave of gastrointestinal smooth muscle contraction begins at the oral end and moves to the anal end".

In much of the gastrointestinal tract, smooth muscles contract in sequence to produce a peristaltic wave which forces a ball of food (called a bolus) while in the esophagus.

Johnny stood calmly, watching the Wheel, and now it seemed to her (although it might have been the sickness, which was now rolling through her belly in gripping, peristaltic waves) that his eyes were almost black.

But in Hollinghurst's new novel, "The Stranger's Child" (Knopf; $27.95), the Jamesian cadences come in peristaltic waves: "This large claim seemed rather to evaporate in its later clauses."

Once acid has entered the lower esophagus peristaltic waves initiated within the body of the oesophagus sweep the bolus away into the stomach, but may still leave a juxtamucosal acidic environment in the lower oesophagus.

These motor complexes help trigger peristaltic waves, which facilitate transportation of indigestible substances such as bone, fiber, and foreign bodies from the stomach, through the small intestine, past the ileocecal sphincter, and into the colon.

Occurring between meals, the migrating motor complex is a series of peristaltic wave cycles in distinct phases starting with relaxation, followed by an increasing level of activity to a peak level of peristaltic activity lasting for 5-15 minutes.

Visual mean values of UOS pressure were taken for each two second interval from 10 seconds before the onset of the common cavity episode until one second before the first swallow after the common cavity episode, or the onset of the first secondary oesophageal peristaltic wave (Fig 3).
