The Yoake-bone [tab. 7. figur. 6.VX] is called 〈 in non-Latin alphabet 〉〈 in non-Latin alphabet 〉, because it is made of two bones * 1.1 ioyned together. It is seated in the side of the face vnder the orbe of the eye. This is no peculiar bone though it haue a pecular name, but is compounded of two processes of two seuerall bones: one of the Temple bone another of the first bone of the vpper iaw, which two processes are in the middest ioyned together by an oblique suture [ta. 7. fig. 6.Y table 8. figur. 8.P] and so make one bone like a yoake, although me thinks it is better dompared to a bridge. On the outside it is gibbous, within hollow. The rootes on either side are thicke, but the middle of the processe which yssueth out of the Temple bone is but slen∣der.
The substance of it is hard and almost solid, almost I say, for it hath a cauity in it, such as it is, wherein it contayneth marrowe for his nourishment, yet is it somewhat solid too, * 1.2 the better to defend the Temporall muscle, especially his Tendon, before which it is pla∣ced, from outward iniuries: beside the muscle called manforius taketh his originall there∣from, and againe it strengthneth the Scull which is there but thinne. And finally sayeth Platerus and with him Laurentius, it giueth a great strength vnto the orb of the eye which swelleth out a little aboue it. And so much of the yoake bone: now we proceede vnto the vpper Iaw.
