• Body's largest organ?

  skin
• Why skin is considered as an organ?

  It consists of several types of tissues that function together.
• An epidermal hairless skin usually found in the palms and soles.


  Friction Skin
• Where are the fingerprints formed?

  Friction Skin
• The biological function to assist in our ability to grasp and hold onto objects.

  Friction
• The outer covering the skin.

  Epidermis
• The two main layers of the epidermis.

  Stratum Corneum

  Stratum Mucosum
• Five Subdivision of Stratum Corneum.

  Corneous layer

  Transparent Layer

  Granucar Layer

  Malpghian Layer

  Generating Layer
• The inner layer of the skin containing blood vessels, various glass and nerves. This is where the dermal papillae are found.

  Dermis
• The three layers of the skin?

  Epidermis

  Dermis

  Subcutaneous tissue
• Where are fingerprints generally found?


  Human Skin
• Tiny elevation of hill like structures found on the epidermis layers of the skin containing sweat pores. It appears black lines with tiny white dots called pores in an inked impression

  Ridges
• Component of the friction skin that actually forms the fingerprint impression.

  Ridge Surface
• Canal like impression or a depression found between the ridges which may be compare with the low area in a tire thread.


  Furrows
• Are found in the dermis layer of the skin which is responsible for the production of sweats.

  Sweat Glands
• Long host like structure that serves as the passage way for the sweat that exists as its mouth, the pore.

  Sweat Duct
• A small opening found anywhere across the ridge surface where the sweat comes out.

  Sweat Pores
• Ridge begin to form on the human fetus during what?

  3rd to 4th months of the fetus.
• Located on the forehead, chest, back, and abdomen with oily secretion called sebum


  Sebaceous Glands
• Are found in the pubic, mammary and anal areas.

  Apocrine Glands
• Kind of sweat glands that are found in all parts of the body and are only sweat glands found on the palms of the hand and the soles of the feet.

  Eccrine Glands
• How many human bones in human hands?

  27 bones
• A phalange of the finger located at the base portion just below the middle phalange.

  Basal Phalange
• The phalange of the finger located at the middle of the terminal and basal phalange.

  Middle Phalange
• The particular bone that is covered with the friction skin having all the different types of patterns and located near the top of the finger.

  Terminal Phalange
• Born with missing finger.

  Ectodactyl
• Having small finger

  Microdactyl
• Having enlarged finger.


  Macrodactyl
• Side fusion of the fingers.

  Syndactyl
• Born with more than ten fingers.

  Polydactyl
• It refers to the details of ridge structures, formation, and elements, which differentiate from one fingerprint to another and which impart individuality to each part.

  Ridge Characteristics
• Another term for Ridge Characteristics?

  Minutiae
• A single ridge that divides itself into two or more branches. It is sometimes called "fork".

  Bifurcation
• A ridge fromation characterized by a closed angular end and serves as a point of converge.

  Converging
• Two ridges that are flowing side by side and suddenly separating or spreading apart.

  Diverging Ridge
• A ridge that divides into two branches and meats to form the original ridge.

  Enclosure (Lake or Eyelet)
• An end point of the ridge with abrupt ending; single friction ridge that terminates with the friction ridge structure.

  Ending Ridge
• A kind of ridge fromation that curves back in the direction from which it started.

  Recurving Ridge or Loop Ridge
• A recurving ridge complete in its shoulder and is free from any appendage.

  Sufficient Recurve
• A short ridge found at the top or summit of a recurving ridge.

  Appendage (attachment or connection)
