What are Langer's lines?

Langer lines are areas of tension in the skin created by basic collagen structures. The wounds created parallel to the lines tend to take the form of narrow slots, while perpendicular injuries will be afraid because they are pulled by tension. This may have important consequences for surgery, especially in cosmetic procedures, where the aim may be to minimize the appearance of the scar. Forensic pathologists are also interested in Langer's lines, as they may affect the appearance of the injury and may be important to consider wounding. Other anatomists took note of the basic tension patterns in the skin, but Langer conducted practical research to describe and map them. He used a distinctive circular tool to strike the skin and created a number of injuries to notice how the skin reacted. During his experiments, he made several important observations. He was able to create a general map of lines on his body, but noted that different people could have slightly different orientations. In addition, they were dependent on the position. Someone who lay had, for example, other formulas onFive than someone who bends. His experiments relying on the corpses were not the perfect illustration of how the tension of the skin in the body behaved, because its entities were unable to represent dynamically.

Despite some problems with Langer lines can be a useful tool. During surgery, the cuts can be placed in parallel with voltage if possible to reduce the risk of creating a gap of surgical wounds. Reducing tension can also mean that the edges of the injury will be less pulled during healing. This can be reflected in the reduced Bolester of the patient and smaller scars. For very small cuts, the surgeon can try to hide the cut in the fold of the skin, so the scar will be invisible after recovery.

In addition, pathologists are considering Langer's lines when they evaluate bodies. The shape of the injury can depend on how the weapon enters the body and where the factor in evaluating the victims of crimes is important. Laying can also be a mineears. By the nature of the injury, the pathologist can be able to determine how the victim was placed at that time, based on the angle of entry and other wound characteristics.
