Explains the most important events in the history of fingerprints and their early uses.
Explains the anatomical structure of friction ridge skin; it provides a basic description of the different layers of the skin and their structure and condition. Ridges and furrows, incipient ridges and pores are also illustrated.
Briefly explains several biological mechanisms involved in the embryogenis development of friction ridges and their patterns.
Explains fingerprints. It describes: 1) general characteristics (Level 1) such as ridge flows, core, delta and main patterns, 2) particular characteristics (Level 2) such as minutiae, 3) microscopic characteristics (Level 3) such as pores and edge structures.
Explains lower phalange prints (lower joints) and describes the morphology of the friction ridges of the other phalanges of the fingers.
Explains palmprints and describes the morphology of the friction ridges of the palms.
Explains soleprints and describes the morphology of the friction ridges of the feet.
Explains the most common conditions that produce friction ridge disorders (poor quality prints), such as creases of the skin (white lines), aging, injuries (scars), occupational marks, exposure or contact with harmful substances, medical disorders, alteration of sweat production and effects of medicine and therapies.
