Catgut suture is straw-colored, and is available in sizes USP 6-0 (1 metric) to USP 3 (7 metric). Although the name implies the usage of guts of cats, there is no record of feline guts being used for this purpose. The word catgut is derived from the term kitgut or kitstring (the string used on a kit, or fiddle).
In anatomy, a suture is a fairly rigid joint between two or more hard elements of an organism, with or without significant overlap of the elements. [1]Sutures are found in the skeletons or exoskeletons of a wide range of animals, in both invertebrates and vertebrates.
A surgical suture, also known as a stitch or stitches, is a medical device used to hold body tissues together and approximate wound edges after an injury or surgery. . Application generally involves using a needle with an attached length
Regions of the suture line and variants in suture patterns Ammonite clean cut . While nearly all nautiloids show gently curving sutures, the ammonoid suture line (the intersection of the septum with the outer shell) is variably folded, forming saddles ("peaks" that point towards the aperture) and lobes ("valleys" which point away from the ...
Rostral suture – is only present when the trilobite possesses a rostrum (or rostral plate). It connects the rostrum to the front part of the dorsal cranidium. Hypostomal suture – separates the hypostome from the doublure when the hypostome is of the attached type. It is absent when the hypostome is free-floating (i.e. natant). it is also ...
Note – catgut is no longer used in the UK for human surgery. [citation needed] A synthetic adsorbable suture material. Braided synthetic adsorbable multifilament made of polyglycolic acid and coated with N-laurin and L-lysine, which render the thread extremely smooth, soft and knot safe. A synthetic adsorbable suture material.
Sutures (or suture lines) appear where each septum contacts the wall of the outer shell. In life, they are visible as a series of narrow wavy lines on the outer surface of the shell. Like their underlying septa, the sutures of the nautiloids are simple in shape, being either straight or slightly curved.
Catgut (also known as gut) is a type of cord [1] that is prepared from the natural fiber found in the walls of animal intestines. [2] Catgut makers usually use sheep or goat intestines, but occasionally use the intestines of cattle, [3] hogs, horses, mules, or donkeys. [4] Despite the name, catgut is not made from cat intestines.
