#anomaly

• ab origine - A Latin phrase meaning 'from the origin' or 'from the very beginning'. In medical genetics and embryology, it is used to describe a chromosomal anomaly, congenital malformation, or metabolic disorder present in the organism's biological framework since the moment of conception (ab origine), as opposed to conditions acquired later in life.
• aber - A neologic etymological root or abbreviated old medical variant for 'aberant' (aberrant, as found in anatomical structures like 'arteria aber'), utilized in early 20th-century Romanian and French surgical manuscripts. It denoted a blood vessel, nerve pathway, or glandular duct exhibiting a localization anomaly or deviation from the standard anatomical trajectory, analyzed to avoid accidental intraoperative injuries.
• aberanță - A state, manifestation, or structure presenting a pathological deviation from the normal or physiological type. In genetics, it represents a structural or numerical anomaly of chromosomes; in neuropsychiatry, it denotes a wandering of cognitive functions or a severe thought disorder; in ophthalmology, it indicates an optical error of the eye (refractive defect) preventing a clear image on the retina.
• aberație - A clear departure from what is normal, correct, logical, or natural. In genetics, it represents a profound modification in the number or sequence of genes within a chromosome (genetic aberration). In psychiatry, it denotes a thought disorder, a bizarre idea, or a severe behavioral deviation from social norms. In optics and astronomy, it indicates image distortion due to lens properties or the Earth's movement through space.
• aberativ - Characterized by aberration; generating deviations, anomalies, or distortions relative to a biological, physical, or logical norm. In optics, it describes a refractive medium or lens that introduces phase or spherical distortions into the light beam. In biology, it refers to mutagenic factors or processes that cause abnormal structural changes in the genetic material.
