Etymology

From Ancient Greek ἀ̆κρᾰ (akra), probably back-formed from German Akren as this is more easily encountered and even the English is most likely found in books written by Germans.

Noun

acra pl (plural only)

1. (anatomy, rare) The vascular areas of the body most removed from the heart

     The principal differential diagnostic considerations in the case of nevi situated at the acra are atypical nevus and melanoma and, occasionally Spitz nevus/tumor.

   • 2014 July 29, Ückert, Sandra, Cold Application in Training & Competition: The Influence of Temperature on Your Athletic Performance, Meyer & Meyer Verlag, →ISBN, page 52:

     The surface area to volume ratio requires that the surface temperature in the nearly cylinder-shaped body parts should be lower the smaller their radius is. Consequently skin temperatures drop toward the ends of the extremities. A quicker cooling of the acra compared to head or trunk also occurs.
