perforating (Sharpey's) fibers
Central canals extend longitudinally through bone tissue and transerse perforating canals connect them. -Brandy James :)
Sharpey's fibers
I believe the perforating gastric ulcer releases the acid, inside the stomach, which can then damages the pancreas, due to how close the pancreas and stomach are.
Canals in the bone in which blood vessels pass. Blood vessels from outside the bone penetrate the compact bone to the spongy bone through the PERFORATING CANALS.
Perforating (Volkmann's ) canals.
bundles of collagenous fibers that pass into the outer circumferential lamellae of bone or the cementum of teeth.
A perforating gastric ulcer can be fatal. The spewing of gastric acids can damage all organs that the acid comes into contact with. The pancreas is exceptionally susceptible to the acid both from the exterior and the interior as it is the first place the acid is directed to for elimination.
The perforating (Volkmann) canals, that run horizontally in compact bone and connect to the central canal.
Other passageways, known as perforating canals or Volkmann's canals, extend perpendicular to the surface. Blood vessels in these canals supple blood to osteons deeper in the bone and to tissues of the medullary cavity.

A perforating service is the act of perforating holes thru the steel caseing, thru the cement used to secure and seal the caseing to the earth, and out into the oil or gas producing zone. Perforating a well uses a wireline truck which contains a large spool of wire line or cable. Inside the wireline or cable are electrical wires that are used to run special equipment on board the truck to locate the oil zone. After the zone is located, this same wire line is used to lower the "perforating gun" into the caseing and locate it properly. After the proper location is established the electrical wires are used to detonate explosive charges that do the actual perforating of the caseing,cement and oil zone. These "perforations" or holes, are where the oil or gas enter the caseing to be produced at the surface. Usually the same company that dose the perforating of an oil well, will have other services that use the same cable, spool and electrical wireing. These services are known as "logging" and consist of electronic equipment that help the oil man determine if the well has penetrated an oil or gas zone. Measurements such as thickness, oil or water content of the zone, percent of permability etc. can be determined from these verious logs.
