Flying, fear of
|
|
Flying, fear ofAn irrational fear of flying is called aerophobia. Aerophobia also refers to irrational fear of fresh air or drafts of air. A virtual reality program that simulates the experience of take-offs, landings, normal flying and turbulence reportedly helps some people overcome their fear of flying.
RELATED TERMS--------------------------------------
Aerophobia
"An abnormal and persistent fear of flying. Sufferers experience severe anxiety even though they usually realize that the flying does not pose a threat commensurate with their fear. Aerophobia also means an irrational fear of fresh air or drafts of air. Derived from the Greek ""aero-"", air or gas + ""phobos"", fear = literally, fear of air."

PREVIOUS AND NEXT TERMS--------------------------------------
Fluoroscopy
An x-ray procedure that makes it possible to see internal organs in motion. Fluoroscopy uses x-ray to produce real-time video images. After the x-rays pass through the patient, instead of using film, they are captured by a device called an image intensifier and converted into light. The light is then captured by a TV camera and displayed on a video monitor.
Fluorosis
An abnormal condition caused by excessive intake of fluorine, characterized chiefly by mottling of the teeth.
Fluorouracil
A much-used anticancer drug that belongs to the family of drugs called antimetabolites. Full name: 5-fluorouracil. Abbreviation: 5-FU. 5-FU is a pyrimidine antagonist. 5-FU is similar in structure to the pyrimidine base thymine and functions to inhibit DNA synthesis both by blocking the formation of normal pyrimidine nucleotides via both enzyme inhibition and by interfering with DNA synthesis after incorporation into a growing DNA molecule. 5-FU is also able to block the production of RNA and thereby induce cell death. 5-FU affects the processing of messenger RNA (mRNA), ribosomal RNA (rRNA), transfer RNA (tRNA), and small nuclear RNA (snRNA). 5-FU may also inhibit cell growth is through its ability to prevent the synthesis of thymine nucleotides from uracil nucleotides.
Flush
(1) A redness of the skin, typically over the cheeks or neck. A flush is usually temporary and brought on by excitement, exercise, fever, or embarrassment. Flushing is an involuntary (uncontrollable) response of the nervous system leading to widening of the capillaries of the involved skin. Also referred to as a blush (or, as a verb, to blush). Flushing may also be caused by medications or other substances that cause widening of the capillaries, such as niacin. (2) Flush also means to wash out a wound or body area.
Flutter, atrial
Well-organized but overly rapid contractions of the atrium of the heart (usually at a rate of 250-350 contractions per minute).
Flying, fear of
FMDV
Foot-and-mouth disease virus.
FMF (familial Mediterranean fever)
An inherited disorder featuring short recurring crises of severe abdominal pain and bouts of fever. Other symptoms include arthritis, chest pain from inflammation of the lung cavity, and skin rashes. Between attacks, the patient seems healthy. Amyloidosis (the abnormal deposition of a particular protein, called amyloid, in various tissues of the body) is a potentially serious complication and can develop without overt attacks of FMF. The kidney is a prime target for the amyloid.
FMO3
Abbreviation for the enzyme, flavin-containing monooxygenase-3.
FMR1
The gene responsible for the production of a protein called FMRP. Lack of FMRP results in the fragile X syndrome. (FMRP is an acronym composed of the first letters of Familial Mental Retardation Protein).
FMRP
As stated in the entry for FMR1, FMRP is an acronym composed of the first letters of Familial Mental Retardation Protein.
