Friction ridges or papillary ridges Elevated strips of skin that begin as raised apertures around the pores and then are joined together into rows forming the ridges. No two individual posses same ridge characteristics. Best Answer. Criminalistics 1: Personal Identification Criminalistics Personal The number, relative location and identity of the characteristics impart individuality to a fingerprint. The ridges make a backward turn in loops but they do not twist. Left thumb conversion for ridge counts: 1 to 11 small (S), 12 to 16 medium (M), 17+ large (L) Right thumb: If the ridge count of the left thumb is 16 or less, the same conversion is used for the left and . 10 fingers of 2 hands are divided into 5 groups in following manner. For the plain arch, for calculation purpose, a point in a ridge which has a high peak is chosen as core and a point in the bottom-most ridge, which is almost straight, is chosen as a delta point. The low point on a ridge is called a col or saddle. This is the highest occurrence in comparison with other RC counts. Now customize the name of a clipboard to store your clips.
