THE Ligaments of the Head doe some of them belong to the whole Head, some to particular parts thereof: the whole Head is mooued aboue the first * 1.1 and the second vertebra or spondell of the necke, wherefore it was needfull that it shold be fastned with strong ligaments, otherwise a notable part had bin in danger of luxation. Of these Ligaments Bauhine reckoneth 4; Lau∣rentius but three, which notwithstanding (sayeth hee) may bee deuided into more par∣ticles.
The first is a very great and broade Ligament which tyeth the first Racke-bone vnto * 1.2 the Head and compasseth the whole ioynt round about. It hath two portions, one like a thicke membrane and runneth to the inside of the first spondel, the other part compasseth about the outside of the ioynt. It ariseth out of the Basis of the occiput or Nowle of the head, which is therfore exasperated, and in young children is scotched or cleft manifold: hence it is that the first and second vertebrae may sooner be broken then luxated.
The second Ligament fastneth the processe of the second Rackbone called the Tooth * 1.3 to the head, and it consisteth of three parts. Two arising from the outside of the Tooth are inserted into the inside of the circumference of the hole which is in the nowle-bone. The third is round like a nerue and ariseth from the foreside of the Tooth, and is infixed like∣wise into the hole of the Nowle to which it adheareth very strongly.
The third Ligament is very like a nerue and made with wonderful art, and compasseth * 1.4 the cauity of the first Racke-bone which was made to receiue the Tooth of the second, & constringeth the sayde tooth, so firming it that it cannot incline to either side; it safeguar∣deth also the spinall marrow least it should offend against the bare bone.
The fourth Ligament ioyneth the second Racke-bone to the first. It is membranous * 1.5 and of the same nature and vse with the other ligaments of the ioyntes; and these are the common ligaments of the head. There are also other proper ligaments in the head which belong to particular parts: as the ligament of the gristle of the Eare: a strong ligament, for it fastneth the roote of the gristle to the stony-bone, and ariseth with diuers propaga∣tions * 1.6 from the Pericranium, where it tendeth toward the Mammillary processe. These pro∣pagations when they come vnto the care do grow together into one ligamēt & it is inser∣ted into the vpper & gibbous part of the care to hold the gristle pricked vp & suspended.
There is a ligament also in the Eye called by Falopius, Ligamentum Ciliare, not because it is of the nature of a ligament, but because the grapy coat is thereby fastned to the verge * 1.7 or circumference of the membrane of the Christalline, but wee haue spoken of it suffici∣ently before in the end of the 7. Chapter of the 8. Booke.
The Ligaments of the vpper Iaw betweene the sutures and the harmonies are thin and * 1.8 membranous, made for the original of the muscles, for from them the tendons of the mus¦cles of the Face and of the neighbour partes take their originall. The articulation also, sayth Galen in the 20. Chapter of his first booke de vsu partium, of the lower Iaw with the Temple bones hath strong ligaments, which Bauhine out of Platerus calleth a common membranous ligament incircling the whole ioynt.
The Ligament of the Tongue Galen discourseth of in the 10. chapter of his 11. booke de vsu partium. It is strong, membranous and broad, but of it wee haue spoken before in * 1.9 the 32. chapter of the 8. booke. Of the ligaments of the bone Hyois we shall speake in the booke of Bones. Of the ligaments in the Heart, in the Rough Artery and the cutany li∣gament of the wombe we haue spoken before in their proper places, which wee will not now stand to repeat, but proceed on vnto the ligaments of the Spine and the Chest.
