autotomyn.

Brit.

/ɔːˈtɒtəmi/, U.S.

/ɔˈtɑdəmi/,

/ɑˈtɑdəmi/

Origin: Formed within English, by compounding; partly modelled on a German lexical item, and partly modelled on a French lexical item. Etymons: auto- comb. form¹, -tomy comb. form.

Etymology: < auto- comb. form¹ + -tomy comb. form, after German Autotomie (1884) and its model French autotomie (L. Fredericq 1883, in Arch. de zoologie expér. 1 413). Compare earlier autotomic adj.

Chiefly Zoology.

The casting off or ejection of a part the body as a reflex action in certain animals when they are disturbed or attacked. In later use also: self-harming of a denervated limb by a laboratory animal.

1887 Sc. Rev. July 205 ‘Zoology’ is confined to two subjects to which attention has been given in former numbers. The first of these is ‘Autotomy’, the other is the more practical question of the sardine fisheries.

1901 T. H. Morgan Regeneration 154 One of the most remarkable cases of autotomy is that in holothurians, in which the Cuverian organs, and even entire viscera, may be ejected when the animal is disturbed.

1919 J. A. Thomson Secrets Animal Life xxii. 167 The highest level at which autotomy is practised is among lizards.

1979 P. D. Wall et al. in Pain 7 103 When hindlimb peripheral nerves are cut across in rats and mice, there is a tendency for the animal to attack the anaesthetic limb. We have called this attack ‘autotomy’.

1992 Anesthesiology 76 1069 There is strong evidence that autotomy [in rats] is a response to painful or dysesthetic sensations referred to the anesthetic limb.

2005 T. M. Caro Antipredator Defenses in Birds Mammals xii. 431 Among invertebrates, autotomy of appendages is widespread.
