enteritis

Examples of enteritis in the following topics:

• Enteric Nervous System

  • The enteric nervous system is embedded in the lining of the gastrointestinal system.
  • The enteric nervous system can operate autonomously.
  • The parasympathetic nervous system is able to stimulate the enteric nerves in order to increase enteric function.
  • Conversely, stimulation of enteric nerves by the sympathetic nervous system will inhibit enteric function and capabilities.

• Connecting Proteins to Glucose Metabolism

  • Excess amino acids are converted into molecules that can enter the pathways of glucose catabolism.
  • Metabolic pathways should be thought of as porous; that is, substances enter from other pathways and intermediates leave for other pathways.
  • The keto acid can then enter the citric acid cycle.
  • Deaminated amino acids can also be converted into another intermediate molecule before entering the pathways.
  • Several amino acids can enter glucose catabolism at multiple locations.

• Entry Barriers

  • One important source of oligopoly power are barriers to entry: obstacles that make it difficult to enter a given market.
  • Barriers to entry are obstacles that make it difficult to enter a given market.
  • The term can refer to hindrances a firm faces in trying to enter a market or industry—such as government regulation and patents, or a large, established firm taking advantage of economies of scale—or those an individual faces in trying to gain entrance to a profession—such as education or licensing requirements.
  • This means that new firms cannot enter the market whenever existing firms are making a positive economic profit, as is the case in perfect competition.
  • For example, requirements for licenses and permits may raise the investment needed to enter a market, creating an effective barrier to entry.

• Performed individually

  • It is possible that individuals can learn from this activity and not enter the cycle of experiential learning.

• The Chi-Square Distribution: Test for Homogeneity

  • Press 2 ENTER 4 ENTER.
  • Press ENTER.
  • Press ENTER.
  • Press 2 ENTER 3 ENTER.
  • Press ENTER.

• The Legume-Root Nodule Symbiosis

  • Exposure to nod factor triggers the formation of deformed root hairs, which permit rhizobia to enter the plant.
  • Rhizobia then form an infection thread, which is an intercellular tube that penetrates the cells of the host plant, and the bacteria then enter the host plants cells through the deformed root hair.
  • Rhizobia can also enter the root by inserting themselves between cracks between root cells; this method of infection is called crack entry.
  • Bacteria enter the root cells from the intercellular spaces, also using an infection thread to penetrate cell walls.
  • Root nodules are formed when nitrogen fixing bacteria called rhizobia enter the cells of a host plant.

• Autonomic Nervous System (ANS)

  • The enteric nervous system is sometimes considered part of the autonomic nervous system, and sometimes considered an independent system.
  • Stimulation of the enteric nerves by the sympathetic system inhibits GI activity.
  • It does this in a minor way with the direct effect of its secreted norepinephrine, and in a major way by inhibiting action in the enteric plexuses.
  • Some have their cell bodies in the enteric plexus, and some in the spinal cord.
  • An illustration of neural control of the gut wall by the autonomic nervous system and the enteric nervous system.

• Connecting Other Sugars to Glucose Metabolism

  • Sugars, such as galactose, fructose, and glycogen, are catabolized into new products in order to enter the glycolytic pathway.
  • Metabolic pathways should be thought of as porous; that is, substances enter from other pathways, and intermediates leave for other pathways.
  • Glycogen is broken down into G-1-P and converted into glucose-6-phosphate (G-6-P) in both muscle and liver cells; this product enters the glycolytic pathway.
  • Galactose is converted in the liver to G-6-P and can thus enter the glycolytic pathway.
  • The glucose can directly enter the glycolytic pathway while fructose must first be converted to glycogen, which can be broken down to G-1-P and enter the glycolytic pathway as described above.

• Dispersion of the Visible Spectrum

  • When white light enters the prism, it spreads.
  • Light enters a drop of water and is reflected from the back of the droplet.
  • The light is refracted once as it enters the drop, and again as is exits the drop.
  • Part of the light falling on this water drop enters and is reflected from the back of the drop.
  • This light is refracted and dispersed both as it enters and as it leaves the drop.

• Fetal Circulation

  • About half of this enters the fetal ductus venosus and is carried to the inferior vena cava, while the other half enters the liver proper from the inferior border of the liver.
  • Some of the blood moves from the aorta through the internal iliac arteries to the umbilical arteries, and re-enters the placenta, where carbon dioxide and other waste products from the fetus are taken up and enter the maternal circulation.
  • Some of the blood entering the right atrium does not pass directly to the left atrium through the foramen ovale, but enters the right ventricle and is pumped into the pulmonary artery.
