Week 1: Fingerprints


A fingerprint is an arrangement called 'fraction ridge skin'. This covers the whole hands and feet, and they consist of tiny ridges and furrows. The ridges on the tips of your fingers are arranged into different patterns which make up your fingerprints.The arrangement of these ridges and furrows are unique to an individual and does not change throughout life, which makes it useful for identification purposes.Skin cells grow on the surface of the skin and fuse to form the ridges. As these ridges form, some fuse, some branch and others break to form individual ridge features and ridge patterns.
