LOOP, ARCH, WHORL

a pattern in which the ridges enter on one side of the pattern then flow toward the other side, with a rise at the center.

PLAIN ARCH

What type of fingerprint pattern is the simplest

PLAIN ARCH

a fingerprint pattern where majority of the ridges form an arch and one or more ridges at the center shape a tent in outline giving an angle of 90 degrees or less or one with an upward thrust having an angle of 45 degrees or more, or a pattern similar to a loop but lacking one or two of its essential elements.

TENTED ARCH

What fingerprint pattern considered as Transitional Pattern"

TENTED ARCH

a fingerprint pattern that has a downward slope or slanting of the ridges towards the direction of the thumb either to the right or left hand.

RADIAL LOOP

GREEK, ULNA, LITTLE FINGER BONE

Is loop is applicable in ridge counting?

YES

Is loop applicable in ridge traacing?

a fingerprint pattern consisting of two deltas and in which at least one ridge makes a turn through one complete circuit of 360 degrees.

PLAIN WHORL

Types of Plain Whorls

ELONGATED OR OVAL WHORL, SPIRAL OR CIRCULAR WHORL

a fingerprint pattern which possesses two deltas, with one or more ridges forming a complete circuit which may be oval, spiral, circular, or any variant of a circle.

CENTRAL POCKET LOOP WHORL

Central Pocket Loop whorl is sometimes called what?

COMPOSITE PATTERN

Means, there are two patterns in one, a whorl inside loop.

COMPOSITE PATTERN

Consists of atleast one recurving ridge, or an obstruction of right at right angle to the line of flow, with two deltas between which, when an imaginary line is drawn, no recurving ridge within the inner pattern is cut or touched.

CENTRAL POCKET LOOP WHORL

A fingerprint pattern consisting of two separate and distinct loop formations with two sets of shoulders, and two deltas.

DOUBLE LOOP WHORL

Double loop whorl is also called what?

COMPOSITE PATTERN

Double loop whorl is made up of any ___ _____, combined into one finger

TWO LOOPS

a double loop formation where ridges form two loops forms letter “S”

S TYPE PATTERN

a double loop pattern that are formed opposite from each other with interlocking ridges.

INTERLOCKING TYPE PATTERN
