what are fingerprints?
1. The three types of fingerprints are:
- an impression left in something soft, such as putty or wet paint
- a print left by a hand covered in dirt, blood or paint
- An in visible deposit left by the secretions from the skin (small amounts of oil and perspiration are secreted from a microscopic person the tiny ridges on the fingerprints and other parts of the body).
2. The fingers or palms are the part of the body that have ridge patterns that allow patterns to be distinctively made.
3. The sweat gland and the sebaceous gland are the two glands on our skin.
- The sweat glands secret water, amino acids, salts and urea through the pores.
- Oil produced by sebaceous glands also oozes onto the skin surface.
4. Secretions of the skin make up invisible fingerprints (small amounts of oil and perspiration from pores and tiny ridge son the fingerprints and other parts of the body)

The fingerprints are completely formed by the fifth month of pregnancy and will never change in shape throughout the person’s life time. if it ever changes it will be because of a result of a major accident or severe injuries, then the injury itself may become as unique and distinctive as the fingerprint it has replaced.
