    Study Notes

    Ridge Structures in Fingerprints

    • Ridge Ending: A ridge that terminates abruptly, considered a key detail in fingerprint identification.
    • Ridge Dot: A small ridge feature that appears as a dot between larger ridges, aiding in fingerprint pattern assessment.

    Lake (Enclosure)

    • Lake (Enclosure): A fingerprint characteristic resembling a small, enclosed space within the ridge structure, often indicating a unique pattern.
    • Primary Characteristic: Appears as a closed loop or area surrounded by ridges, serving as an important marker in analysis.

    Incipient Ridge

    • Incipient Ridge: A developing ridge that is not fully formed, distinguishing it from mature ridge structures.
    • Differentiation: Recognized by its shorter length and incomplete formation compared to fully developed ridges.

    Ridge Characteristics

    • Short Ridge: A ridge that is shorter than typical ridges and does not connect to others, important for identifying specific patterns.
    • Ridge Bridge: Characterized by a connection between two ridges, creating a bridge-like appearance, enhancing fingerprint uniqueness.

    Bifurcation in Fingerprint Patterns

    • Bifurcation: The feature where a single ridge splits into two distinct ridges, crucial in fingerprint classification.
    • Double Bifurcation: Refers to a point where one ridge separates into two separate bifurcations, adding complexity to fingerprint patterns.
