Fingernail

FingernailA fingernail is produced by living skin cells in the finger. A fingernail consists of several parts including the nail plate (the visible part of the nail), the nail bed (the skin beneath the nail plate), the cuticle (the tissue that overlaps the plate and rims the base of the nail), the nail folds (the skin folds that frame and support the nail on three sides), the lunula (the whitish half-moon at the base of the nail) and the matrix (the hidden part of the nail unit under the cuticle).

Skin
Skin is an organ of the integumentary system; which is composed of a layer of tissues that protect underlying muscles and organs. Skin is used for insulation, vitamin D production, sensation, and excretion (through sweat).
Tissue
Biological tissue is a group of cells that perform a similar function.The study of tissues is known as histology, or, in connection with disease, histopathology.The classical tools for studying the tissues are the wax block, the tissue stain, and the optical microscope, though developments in electron microscopy, immunofluorescence, and frozen sections have all added to the sum of knowledge in the last couple of decades.
Base
A chemical compound that either donates hydroxide ions or absorbs hydrogen ions when dissolved in water. Bases and acids are referred to as opposites because the effect of an acid is to increase the hydronium ion concentration in water, whereas bases reduce this concentration. Arrhenius bases are water-soluble and always have a pH greater than 7 in solution.

Finger prick
A procedure in which a finger is pricked with a lancet to obtain a small quantity of capillary blood for testing. Also called a finger stick.

Fingerprint
1. The characteristic dermal ridges on the finger. This is the original meaning of fingerprint. 2. The characteristic pattern of the peptide fragments of a protein that have been subjected to electrophoresis and, at a right angle, chromatography. Peptide fingerprinting was invented by Vernon Ingram in 1957. 3. The characteristic pattern of DNA fragments identified by Southern hybridization or by PCR (polymerase chain reaction).
Fingers, six
The presence of an extra finger, a very common congenital malformation (birth defect). This condition is called hexadactyly. The word hexadactyly literally means six digits. In medical usage, hexadactyly does not specify whether the six digits are fingers or toes.
PREVIOUS AND NEXT TERMS--------------------------------------
Film, tear
The liquid layer bathing the cornea and conjunctiva. It creates a perfectly smooth liquid outer layer that polishes the corneal surface, mechanically traps and flushes out foreign bodies and chemicals, contains bacteriostatic substances that inhibit the growth of microorganisms, and reduces the surface friction associated with eyelid blinking and eye movement.
Filoviridae
A family of viruses that cause hemorrhagic fever. Filoviruses have single- stranded RNA as their genetic material. Ebola virus and the Marburg virus are both filoviruses.

Finished DNA sequence
A DNA sequence in which the bases are identified to an accuracy of no more than 1 error in 10,000 and are placed in the right order and orientation along a chromosome with almost no gaps. A finished sequence is as opposed to a draft DNA sequence.
Fire ant sting
A scourge, these red or yellow ants of small-to-medium size, originally from South America, have a severe sting that burns like fire. Their sting-like that of bees, yellow jackets, hornets and wasps -- can trigger allergic reactions varying greatly in severity. Avoidance and prompt treatment are essential. In selected cases, allergy injection therapy is highly effective.
Fire gilding
A perilous process for gold-plating in which an amalgam of mercury and gold is applied to an object and then exposed to heat to vaporize the mercury and leave the gold behind in a thin layer. Fire gilding also is applicable to plating silver, copper, and copper alloys. The process of fie gilding is still used when antique work is to be repaired or an exact replica made. Fire gilding is hazardous because mercury vapors are emitted even at room temperature, presenting an appreciable risk of mercury poisoning. Fire gilding is also called mercury gilding.
