Origin: Formed within English, by clipping or shortening. Etymon: Latin nervus accelerans cordis.

Etymology: Shortened < scientific Latin nervus accelerans cordis (1873 or earlier in a German source; compare nervus cordis accelerans and nervus accelerans , both 1871 or earlier in German sources) < classical Latin nervus nerve n. + accelerāns , present participle of accelerāre accelerate v. + cordis , genitive singular of cor heart (see cordi- comb. form).

Physiology. Now rare and chiefly historical.

More fully accelerans cordis. Any of the sympathetic nerves supplying the heart and causing its rate of beating to increase. Frequently attributive, esp. in accelerans nerve. Cf. accelerator n. 2.
