Furcula

In a barb, which in all its measurements was a little larger than the same rock-pigeon, the furcula was a quarter of an inch shorter. ❋ Charles Darwin (1845)

These arthropods have a fork-like structure (called furcula) at the hind end that is hooked under their abdomen. ❋ Unknown (2010)

The wishbone, called a furcula, is the fusion of two collarbones at the sternum. ❋ Unknown (2009)

- Snow fleas, like all springtails, have an unusual appendage (a furcula) that folds under the abdomen and can be used to suddenly propel the insects several inches. ❋ Unknown (2010)

I took 2 photos of it before it deployed its furcula and disappeared into thin air. ❋ AYDIN (2007)

But Archaeopteryx was very likely capable of powered fligh sic judging from its relatively massive furcula and the asymmetric rachis of its primary flight feathers Feduccia and Tordoff 1979; Olson and Feduccia 1979. ❋ Unknown (2005)

Mucrones: in Collembola the two small end pieces of the furcula, proceeding from the dentes. ❋ John. B. Smith (N/A)

Furca: a fork: the anal appendage used for leaping in Thysanura; see furcula: the forked ental processes of the sternum. ❋ John. B. Smith (N/A)

Gilbert, of course, supplies a formidable array of remedies for the disease, but tells us that the "very latest" is cauterization over the clavicles (_Novissimum autem consilium est cauterium in furcula pectoris_). ❋ Henry Ebenezer Handerson (N/A)

The first rudiment of the larynx consists of two arytenoid swellings, which appear, one on either side of the cephalic end of the laryngo-tracheal groove, and are continuous in front of the groove with a transverse ridge (furcula of His) which lies between the ventral ends of the third branchial arches and from which the epiglottis is subsequently developed (Figs. 980, 981). ❋ Unknown (1918)

This elevation was named by His the furcula, and is at first separated from the tuberculum impar by a depression, but later by a ridge, the copula, formed by the forward growth and fusion of the ventral ends of the second and third arches. ❋ Unknown (1918)

The size and shape of the apertures in the sternum are highly variable; so is the degree of divergence and relative size of the two arms of the furcula. ❋ Unknown (1909)

He read about the construction and habits of the owl: "In the tawny, or brown, owl there is a manubrial process; the furcula, far from being joined to the keel of the sternum, consists of two stylets, which do not even meet; while the posterior margin of the sternum presents two pairs of projections, with corresponding fissures between." ❋ John Galsworthy (1900)
