CHAP. XX. Of the sixt, seauenth, and eight Coniugations of the Sinewes.

THE sixt Coniugation [Tab. 21, fig. 1, and 2, ^e Tab. 15, fig. 20. ^N] taketh his be∣ginning of a few fibres a little below the originall of the Nerue of hearing. These Nerues being instantly vnited doe make one notable Nerue as some haue thought, but indeed they are neuer so vnited but that they remaine two * 1.1 Nerues contained or held together in one membrane, and passe out at one hole, [Tab. 4, fig. 10. ^b] which is counted the 2. hole of the occipitium or Nowle-bone. The one of those is the forwarder & the lesser: the other the backwarder & the greter. The lesser runneth directly to the muscles of the tongue, and for the most part is spent in the mouth; * 1.2 the greater as soone as it is issued out of the Scul sendeth a branch backward [Tab. 21, fig. 2, ^f] which is diuersly distributed into the Mūcks-hood muscle of the shoulder blade. The trūk it selfe descending is tyed to the seauenth Coniugation, [Tab. 21, fig. 2. ^H] and at the sides of the throtle is increased with a branch from that seauenth Coniugation, [Table. 21, fig. 2, ⁱ] * 1.3 with which notwithstanding it is not mingled but onely colligated or tyed: after it sendeth surcles to the muscles of the Layrinx or throtle, [Tab. 21, fig. 2. ^g] as also some other smaller to the muscles of the Chops, thence it descendeth to the Chest, where we will leaue it til another time.

The seauenth Coniugation [Ta. 21, fig. 1, ^h fig. 2, ^H] moues the tongue, and is the hardest * 1.4 of all the sinewes proceeding out of the Scull; for it ariseth iust at the place where the mar∣row of the braine falleth out of the Scul. [Tab. 21, fig. 1, 2, ^E] It ariseth of many Roots some∣what * 1.5 distant each from other, which ioyning together into one do passe out of the Scull at an oblique hole bored in the bone of the Occipitium, and for more security is ioyned by strong membranes with the sixt Coniugation, yet not mingled therewith. For this seauenth paire keepeth his owne body and so runneth downward to the roote of the tongue, where * 1.6 the most part of it [Ta. 21, fig. 2, ^Z] is loosened into many fibres which giue motion therto. Other parts of it are deriued to the muscles of the bone Hyois and the Throtle to giue them motion; some surcles also it sendeth [Ta. 21, fig 2, ^l] to those muscles that arise from the ap∣pendix called Stylo-ides.

The eight Coniugation [Tab. 21, fig. 1, 2, ^d Table. 15, fig. 20, ^L] proceedeth out of the * 1.7 marrow of the braine aboue the Auditory Nerue betwixt the second and the third Coniu∣gations.

It perforateth betwixt those 2. paires the thicke Meninx and attayneth into the orbe of the eye through the hole that belongeth to the second coniugation, and is almost wholly spent into that muscle of the eye which draweth it vnto the vtter corner.
