Pronunciation

Origin

Coined by Marshall Hall (physiologist), and first introduced on the 8th of March, 1832 in the reading of his paper entitled “On the Inverse Ratio which subsists between Respiration and Irritability in the Animal Kingdom; and on Hybernation” before the . Despite the initial uptake of this term, it failed to thrive, and is unattested beyond 1835, a mere three years after its coining.

Full definition of arterio-contractile

Adjective

1. (physiology, obsolete) Undergoing contraction due to stimulation by arterial blood. 1832–1835
• 1832: Philosophical Magazine, volume 11, page 454From the facts detailed by Harvey, Goodwyn and others, which establish that in asphyxia the left ventricle of the heart ceases to contract before the right ventricle, the author infers that the irritability of the latter is greater than that of the former; and proposes to distinguish the first as arterio-contractile, and the latter as veno-contractile, from the circumstance of their being stimulated respectively by arterial and by venous blood.
• 1833: The London Medical and Physical Journal, volume 69, page 58In fact, in the midst of a suspended respiration, and an impared condition of some other functions, one vital property is augmented. This is the irritability, and especially the irritability of the left side of the heart. The left side of the heart, which is, in the hybernating animal, in its state of activity, as in all the other mammalia, only arterio-contractile, becomes veno-contractile.
• 1835: James Frederick Palmer ed., The Works of John Hunter (surgeon): with notes, volume 3, page 78, footnote aGoodwyn conceived that the heart ceased to act because the left side, being only arterio-contractile, was incapable of being stimulated by venous blood; but this idea was fully disproved by the experiments of Bichat, which render it certain that the blood stimulates the ventricles not by its quality, but by its bulk.
