1615 H. Crooke Μικροκοσμογραϕια viii. iv. 550 The fourth..is called Abducens and Indignatorius, we may cal it the Scu-muscle or the Muscle of Disdaine.

1694 W. Cowper Μυοτομια Reformata viii. 48 It arises sharp, and Fleshy from the profoundest Part of the Orbit, near the Origination of the Abducens.

1712 Bibliotheca Anatomica II. 92/2 Its rise is sharp and fleshy from the deepest part of the Orbit, near the Origin of the Abducens.

1789 W. Merrick Classical Farrier (ed. 2) 28 And the fourth abducens or indignatorius, from its office of drawing the eye to the outer corner; which turn or aspect of the eye betokens anger or scorn.

1801 D. Hartley Observ. Man (ed. 4) 217 It is worthy of attention here, that the attollentes and deprimentes do not want the same external influence of light to make them move in a congruous manner, as the adducentes and abducentes; in as much as one adducens, and one abducens, must act together to make the eyes move congruously to the right and left.

1841 London Med. Gaz. 1 349/1 The pupil..was drawn diagonally outwards and upwards, as if by the superior rectus, and the upper fibres of the external, or abducens, muscle.

1909 Jrnl. Infectious Dis. 6 526 Twelve days before death unequal pupils and complete paralysis of left abducens muscle developed.

2. More fully abducens nerve. The sixth cranial nerve, which supplies the main abductor muscle of the eye (the lateral rectus).
