Aberration
|
|
Aberration (1) A deviation or irregularity. For example, a chromosome aberration is a deviation from the normal chromosome number or the normal chromosome structure. In this sense, aberration is also synonymous with deflection, departure, divergence, diversion, turning. (2) A mental aberration is a significant deviation from normal mental activity. In this sense, aberration is synonymous with mental derangement, mental illness, psychopathy.
RELATED TERMS--------------------------------------
Chromosome
A structural unit within a eukaryotic nucleus that carries genes. A chromosome consists of a long, continuous strand of DNA and associated proteins.

Abdominal pain
Pain in the belly (the abdomen). Abdominal pain can come from conditions affecting a variety of organs. The abdomen is an anatomical area that is bounded by the lower margin of the ribs above, the pelvic bone (pubic ramus) below, and the flanks on each side. Although abdominal pain can arise from the tissues of the abdominal wall that surround the abdominal cavity (the skin and abdominal wall muscles), the term abdominal pain generally is used to describe pain originating from organs within the abdominal cavity (from beneath the skin and muscles). These organs include the stomach, small intestine, colon, liver, gallbladder, and pancreas.
Abducent nerve
A small motor nerve that has one task: to supply a muscle called the lateral rectus muscle that moves the eye outward. Paralysis of the abducent nerve causes inward turning of the eye (internal strabismus) leading to double vision. The abducent nerve is the sixth cranial nerve. All 12 cranial nerves, the abducent nerve included, emerge from or enter the skull (the cranium), as opposed to the spinal nerves which emerge from the vertebral column.
Abduction
In medicine, the movement of a limb away from the midline of the body. Abduction of both legs spreads the legs. The opposite of abduction is adduction. Adduction of the legs brings them together.
Abductor muscle
Any muscle used to pull a body part away from the midline of the body. For example, the abductor muscles of the legs spread the legs away from the midline and away from one another.
Abductor spasmodic dysphonia
A disorder in which sudden muscle spasms cause the vocal folds (or vocal cords) to stay open. See spasmodic dysphonia.
Aberration
Arterial blood gas
ABG. The sampling of the blood levels of oxygen and carbon dioxide within the arteries, as opposed to the levels of oxygen and carbon dioxide in venous blood. Typically, the acidity, or pH, of the blood is measured simultaneously in ABG sampling.
Abiotic
1. Not associated with living organisms. 2. Anything in the environment incapable of life, such as the soil or weather. 3. Incompatible with life or antagonist to it. Also called abiological.
Abiotrophy
Loss of function or degeneration for reasons unknown. For example, cerebellar abiotrophy may affect coordination while cone-rod abiotrophy may cause blindness at birth.
Ablate
To remove. A tumor may be ablated. To ablate the thyroid gland is to remove it. The word "ablation" came from the Latin "ablatum" meaning to carry away.
