dissection

Examples of dissection in the following topics:

• The Medical Renaissance

  • During the later centuries of the Renaissance, which overlapped with the Scientific Revolution, experimental investigation, particularly in the field of dissection and body examination, advanced the knowledge of human anatomy.
  • His anatomical reports, based mainly on dissection of monkeys and pigs, remained uncontested until 1543, when printed descriptions and illustrations of human dissections were published in the seminal work De humani corporis fabrica by Andreas Vesalius, who first demonstrated the mistakes in the Galenic model.
  • His anatomical teachings were based upon the dissection of human corpses, rather than the animal dissections that Galen had used as a guide.
  • It emphasized the priority of dissection and what has come to be called the "anatomical view" of the human body.
  • The front cover illustration of De Humani Corporis Fabrica (On the Fabric of the Human Body, 1543), showing a public dissection being carried out by Vesalius himself.

• Marfan Syndrome

  • Sometimes, no heart problems are apparent until the weakening of the connective tissue in the ascending aorta causes an aortic aneurysm or aortic dissection; a surgical emergency.
  • An aortic dissection is most often fatal and presents with pain radiating down the back, giving a tearing sensation.
  • If the dilation of the aorta progresses to a significant diameter aneurysm, causes a dissection or a rupture, or leads to failure of the aortic or other valve, then surgery becomes necessary.
  • A micrograph of an aorta with an obvious dissection.

• Defining Anatomy

  • Surface anatomy (or superficial anatomy) is the study of external anatomical features without dissection.
  • This field has moved from examination of animals and cadavers through invasive dissection to the technologically complex techniques developed in the 20th century, such as non-invasive imaging and radiology.
  • Medical and dental students also learn through the dissection and inspection of cadavers.

• Phylum Chordata

  • In this dissected lungfish, which is a member of the chordates, tissues have been dissected away to display the notochord.

• Terpenes

  • Most terpenes may be structurally dissected into isopentane segments.
  • However, the ten carbons in center of the molecule cannot be dissected in this manner.

• Tonsillectomy

  • Removal is typically achieved using a scalpel and blunt dissection or with electrocautery; In some cases, harmonic scalpels or lasers are used.

• Anatomy of the Digestive System

  • Upon gross dissection, the duodenum may appear to be a unified organ, but it is often divided into two parts based upon function, arterial supply, or embryology.

• Anatomical Position

  • Dissection of cadavers was one of the primary ways humans learned about anatomy throughout history, which has tremendously influenced the ways by which anatomical knowledge has developed into the scientific field of today.

• Sacral and Coccygeal Plexuses

  • These two nerves sometimes arise separately from the plexus and, in all cases, their independence can be shown by dissection.

• Applications of Geometric Series

  • His method was to dissect the area into an infinite number of triangles.
