What are the subclasses for fingerprints types? Plain Arch Arch Whorl Loop Accidental Whorl Ulnar Loop Double Loop Whorl Plain Whorl Radial Loop Central Pocket Whorl Tented Arch

Fingerprints are classified into several types based on their general pattern. The main types of fingerprints are:<br /><br />1. Loops: These are the most common type of fingerprint and are characterized by one delta (triangular region) and a single ridge pattern that flows into the delta. There are three subcategories of loops:<br /> - Ulnar Loop: The pattern flows from the little finger side of the hand towards the thumb.<br /> - Radial Loop: The pattern flows from the thumb side of the hand towards the little finger.<br /> - Central Pocket Loop: The pattern is enclosed within the finger itself, forming a pocket-like structure.<br /><br />2. Whorls: These are characterized by two deltas and a circular or spiral ridge pattern. There are several subcategories of whorls:<br /> - Plain Whorl: The pattern consists of at least two complete circles.<br /> - Central Pocket Whorl: The pattern is enclosed within the finger itself, forming a pocket-like structure.<br /> - Double Loop Whorl: The pattern consists of two separate loop formations.<br /> - Accidental Whorl: The pattern does not fit into any of the other whorl categories.<br /><br />3. Arches: These are the least common type of fingerprint and are characterized by a single ridge pattern that flows across the finger. There are two subcategories of arches:<br /> - Plain Arch: The pattern consists of a single wave-like ridge.<br /> - Tented Arch: The pattern has a sharp upthrust in the center, resembling a tent.<br /><br />4. Tented Arch: This is a special type of arch where the ridges form a sharp upthrust in the center, resembling a tent. It is considered a separate category from plain arches due to its unique pattern.<br /><br />It is important to note that the classification of fingerprints can vary depending on the source or organization. The above list provides a general overview of the main types and subclasses of fingerprints.
