Apoptosis vs. necrosis

[CGE at CU.NIH.GOV]

The definition from Dorland's medical Dictionary:

Apoptosis is derived from the Greek Apo- [meaning separation
or derivation from] and -ptosis [silent p, meaning downward
displacement]. Apoptosis = a falling off.

Dale, what is so strange sounding about apo-tosis? There are
many 'pt' words with a silent p - pteridine, pterygoid, Ptolemy,
asymptote, pteridophyte, ptarmigan, ptomaine, and every kids
favorite - pterodactyl.
