pulp chamber

Examples of pulp chamber in the following topics:

• Root Canal Therapy

  • Endodontic therapy is the treatment for the pulp of a tooth which results in the protection of the decontaminated tooth.
  • Root canals and their associated pulp chamber are the physical hollows within a tooth that are naturally inhabited by nerve tissue, blood vessels, and other cellular entities.
  • To cure the infection and save the tooth, the dentist drills into the pulp chamber and removes the infected pulp and then drills the nerve out of the root canal with long needle-shaped drills.
  • After this is done, the dentist fills each of the root canals and the chamber with an inert material and seals up the opening.
  • After removing as much of the internal pulp as possible, the root canals can be temporarily filled with calcium hydroxide paste.

• Spleen

  • Red pulp is the site of blood filtration in the spleen.
  • White pulp is secondary lymphoid tissue that is similar to that in the adenoid tonsils.
  • When blood passes through the red pulp of the spleen, healthy blood cells easily pass, while older red blood cells are caught phagocytized by the macrophages within.
  • Antigens are also filtered by the red pulp, which may be presented to naive lymphocytes in the white pulp of the spleen.
  • This diagram of the spleen indicates the vein, artery, white pulp, red pulp, and capsule.

• The Rumen and Ruminant Animals

  • Ruminant animals (such as deer and cows) digest food in a four-chambered stomach with the help of special bacteria, protozoa, and fungi.
  • Ruminants are mammals that digest plant based food by processing it in a series of chambers in their stomachs.
  • Ruminants differ from non-ruminants (called monogastrics) because they have a four-chambered stomach.
  • The food then enters the first two stomach chambers, the reticulum and rumen (or reticulorumen).

• The 11th Amendment

  • From the 1860s until the 1930s, the court sat in the Old Senate Chamber of the U.S.

• Aerobic Hydrocarbon Oxidation

  • Other applications of biosurfactants include herbicides and pesticides formulations, detergents, healthcare and cosmetics, pulp and paper, coal, textiles, ceramic processing and food industries, uranium ore-processing, and mechanical dewatering of peat.
  • Other applications include herbicides and pesticides formulations, detergents, healthcare and cosmetics, pulp and paper, coal, textiles, ceramic processing and food industries, uranium ore-processing, and mechanical dewatering of peat.

• Bicameralism

  • Bicameralism is the practice of having two legislative or parliamentary chambers.
  • In government, bicameralism is the practice of having two legislative or parliamentary chambers comprise bills.
  • A conference committee is appointed when the two chambers cannot agree on the same wording of a proposal that consists of a small number of legislators from each chamber.
  • Whatever legislation, if any, the conference committee finalizes must then be approved in an unamendable "take-it-or-leave-it" manner by both chambers.
  • During his term as Governor of Minnesota, Jesse Ventura proposed converting the Minnesotan legislature to a single chamber with proportional representation, as a reform that he felt would solve many legislative difficulties and impinge upon legislative corruption.

• Types of Circulatory Systems in Animals

  • Amphibians have a three-chambered heart that has two atria and one ventricle rather than the two-chambered heart of fish (figure b).
  • Some reptiles (alligators and crocodiles) are the most primitive animals to exhibit a four-chambered heart.
  • In mammals and birds, the heart is also divided into four chambers: two atria and two ventricles (figure d).
  • The four-chambered heart of birds and mammals evolved independently from a three-chambered heart.
  • The blood is pumped from a three-chambered heart with two atria and a single ventricle.

• Vertebrate Digestive Systems

  • Vertebrates may have a single stomach, several stomach chambers, or accessory organs that help to break down ingested food.
  • Some animals have a single stomach, while others have multi-chambered stomachs.
  • These chambers contain many microbes that break down cellulose and ferment ingested food.
  • The abomasum, the "true" stomach, is the equivalent of the monogastric stomach chamber.
  • The fermentation process produces large amounts of gas in the stomach chamber, which must be eliminated.

• Scuba Diving, the Bends, and Hyperbaric Oxygenation

  • The equipment required consists of a pressure chamber, as seen in Figure 1, which may be of rigid or flexible construction and a means of delivering 100% oxygen.
  • The chamber cures decompression sickness and gas embolism by increasing pressure, reducing the size of the gas bubbles, and improving the transport of blood to downstream tissues.
  • Again, these dives last for about an hour and can be administered via a hard, high-pressure chamber or a soft, low-pressure chamber - the major difference being per-dive "dose" of oxygen.
  • Many conditions do quite well with the lower dose, lower cost-per-hour, soft chambers.
  • Treatment is by hyperbaric oxygen therapy in a recompression chamber.

• Chambers of the Heart

  • The heart has four chambers.
  • The heart has four chambers through which blood flows: two sets of each type of chamber (atria and ventricles), one per side, each with distinct functions.
  • The atria are chambers in which blood enters the heart.
  • The two larger chambers are the ventricles.
