Grasping Ideas in Words - Natural Learning and Remembering

NOTICE! (CAVIAT) - use General Search Box to find non-medical terms


Comment: Notions in words like life, death, wellness, or love incorporate timeless universal notions represented by mythic figures, emblems, icons, legends, ballads, and lullabies. In a way, such complex notions are like an Egyptian cartouche - a capsule of a cluster of ideas represented by a word (continued at the end of the following list of words). Suggestion: in addition to alphabetic search, if needed, add "word search" in this page (press control F) fuRTHERMORE, the whole Pandora Word Box is dedicate to illuminate meanings conveyed by images and words.

   counselling of conditions that may or may not be of "genetic nature", generally related to
   developmental anomalies (DA) and/or prognosis, associations with other DA, and
   reproductive recurrence or occurrence of similar DA. "Genetic counselling" aspires to be
   non-directional (to empower subjects to make their own decisions), however the term
   "counselling" contradicts such notion. Furthermore, "genetic" "counsellors" are trained
   and certified by similar experts, who generally are minimally trained in Teratology, which
   deals with environmental factors causing DA, for example alcohol. Such "Genetic" vs
   "Teratology" contrast and schism is being bridged by a newly emerging scientific
   discipline, Epigenetics. All DA are the result of modulation by independent epigenetic
   factors of teratogenic impacts regardless if genetic or environmental nature.

   lifespan (includes a mental optimal state) 

~ Helix;

~ Hemangiona; vascular tumor (general term akin to angioma, see ectasia) 

~ Hemi-;

~ Hermaphroditism; strictly speaking, there is no human hermaphroditism. The term
   implies the capacity of self-replication (it negates sexual reproduction). However,
   medical literature uses this term to describe, in most instances, ovo-testes or "mixed
   gonadal dysgenesis" (a high cancer risk anomalies thus an indication for surgical
   removal of such gonads). Pseudo-hermaphroditism, male variety (feminized males)
   and female variety (masculinized females). Personally, I find such "labels" offensive,
   degrading, arrogant, dogmatic and socially damaging. Personally, since the causes
   and pathogenesis of such disorders are multiple and complex, an acceptable alternative
   may be to describe actual clinical features as kindly as possible; gynecomastia for
   example does not have to be branded as an instance of "feminized male" or a large
   clitoris be branded as in instance of a pseudohermaphroditism or equally offensive
   branding as an instance of a "masculinized female". (more in an Overview on this
   subject)

   or

Comment continued: ... While etymology seeks to uncover linguistic roots of words, ideonomy seeks to illuminate clusters of ideas inherent in words. Perhaps a "play with words" such as "what is the idea in the notion of idea" may be a way for others to learn from you answer, what is "on you mind". 

What follows is an informal repository of brief definitions of medical terms with an emphasis on their inherent "ideas". More expansive presentations often are presented in the format "Word Ideas", as "Overviews", and other alternative styles. The access to these entries can be secured by a general search of the contents of Pandora Word Box by using particular key words.
