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)
- (anatomy, rare) The vascular areas of the body most removed from the heart.
- 2004 January 8, Raymond L. Barnhill, Michael Piepkorn, Klaus J. Busam, Pathology of Melanocytic Nevi and Malignant Melanoma, Springer Science & Business Media, →ISBN, page 89:
- 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, Sandra Ückert, 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.
