Forensic Science Flashcards
(12 cards)
Individual/Class characterisitics
class characteristics describe traits common to a group of objects, while individual characteristics are unique to a specific object or person
Red blood cells
components of blood, responsible for carrying oxygen to the body’s tissues and carrying carbon dioxide back to the lungs, red comes from hemoglobin
white blood cells
a crucial part of the body’s immune system, defending against infection and foreign invaders
Cuticle
Outermost layer of a hair shaft
Medulla
Central core of cells within a hair shaft
Root
the follicular structure at the proximal (near the base) end of a hair, where it’s attached to the skin, contains DNA
Kastle-meyer test/phenothalin
a quick and inexpensive chemical test used to presumptively identify the presence of blood at a crime scene
Solemate/treadmark
Treadmark uses four parameters to help identify outside sole impressions to ease time-consuming
recovery.
Solemate is a database holding manufacturer information and several pictorial images to help
determine the type of shoe the print belongs to. This database has over 12,000 different shoes
including work, sports, and casual shoes.
Dactyloscopy
the scientific study and identification of individuals through their unique fingerprints
Ballistics
the scientific examination of firearms, ammunition, and projectile behavior used to solve crimes
Visible prints and latent prints
those that are easily visible to the naked eye due to the transfer of a substance like blood, ink, or paint from a finger or thumb to a surface(visible)
invisible impressions of friction ridge skin (like fingerprints, palm prints, and footprints) that are not readily visible to the naked eye(latent)
Locards principle
“every contact leaves a trace”.
