Swallowing: intro & neural control Questions and Study ...

"The preparation and movement of a bolus during swallowing can be theoretically conceived as a series of valves that must open and close in a coordinated manner. This activity creates zones of high pressure around the bolus and zones of negative pressure below the level of the bolus.

The technique may cause bloating and diarrhoea and bolus delivery into the jejunum can cause a "dumping" type syndrome and should therefore be avoided (see section 10.4). Bolus feeding can be performed using a 50 ml syringe, either with or without the plunger. If the latter is removed, the syringe can be hung up to allow gravity feeding.

Physiology: Gastrointestinal - University of Kansas Hospital

Contraction of the muscle occurs proximal to the bolus, in order to propel the bolus forward. There is a basal level of VIP inhibition in the muscle, and a bolus of food turns off this inhibition: distension of lumen by a bolus will cause inhibition of release of VIP / NO-----> contraction of proximal region.

Changes in Eye Pressure — Causes and Treatment Options

Tests to Detect Changes in Eye Pressure. The test most commonly used to measure intraocular pressure is tonometry, which is often used to screen for glaucoma. A diagnosis of glaucoma will require more than just eye pressure measurement because it is possible to have glaucoma and have normal eye pressure.

Air embolism - Wikipedia

Air embolism can occur whenever a blood vessel is open and a pressure gradient exists favoring entry of gas. Because the circulatory pressure in most arteries and veins is greater than atmospheric pressure, an air embolus does not often happen when a blood vessel is injured.

Peristalsis - Wikipedia

Peristalsis is a radially symmetrical contraction and relaxation of muscles that propagates in a wave down a tube, in an anterograde direction.. In much of a digestive tract such as the human gastrointestinal tract, smooth muscle tissue contracts in sequence to produce a peristaltic wave, which propels a ball of food (called a bolus while in the esophagus and upper gastrointestinal tract and ...

As the bolus passes through the pharynx, low pressure is created at and below the head of the bolus. A modest pressure increase is seen as the bolus passes through the pharynx, and finally, high pressure is observed at the bolus tail, followed by an even larger pressure generation of a clearance event.
