CHAP. III. Of the muscles of the middle belly and of the parts of the necke.
THE Muscles of the middle venter are double, for either they lye vppon the ribbes or are scituated betweene them, yet all of them are not made onely for the motion of the Chest; for albeit they arise from the Chest, yet they moue either the armes or the shoulder blades or the backe or else the Chest it selfe, and such are called the proper muscles of the Chest, & these muscles are placed without or within: those that are seated without are on the forepart or on the back∣part.
1 Pectoralis, the pectorall, and it is the first muscle of the arme, which is broade and large * 1.1 and seated vnder the Pappes.
2 Serratus maior, the greater saw, the second muscle of the Chest which lyeth vppon the ribbs, and to them is inserted as it were with fingers, whence it hath the name of the saw, and occupieth especially the side.
3 Serratus minor, the lesser saw, or the first muscle of the shoulder-blade, it is triangular, and lieth vnder the pectorall muscle.
1 Cucullaris or the Munks-hood the greater part of the second muscle of the scapula or shoul∣der blade.
2 A part of the third muscle of the arme called Latissimus or the broadest muscle, because it taketh vp almost all the back-part of the lower belly.
3 Rhomboydes, the third muscle of the shoulder-blade scituate vnder the Munks-hoode.
4 Serratus Posticus superier, the vpper hinder saw, or the fourth muscle of the Chestlying vnder the Rhomboides.
5 Serratus posticus interior, the lower hinder saw, or the fift muscle of the Chest, scituated vnder the muscle called Latissimus.
6. Sacrolumbus, or the sixt of the chest.
7. Longissimus, the long muscle, the 2. of the backe.
8. Semi-spinatus, the fourth muscle of the backe.
9. Splenij pars inferior, the lower part of the spleniū or of the first muscle of the head placed vnder the vpper hinder saw.
10. Complexi pars inferior, the lower part of the Complexus, or the 2. muscle of the head.
On the inside there is one triangular, the sixt of the Chest; lying vnder the lower part of the brest-bone, of which in the 19. Chapter of this Book. Those muscles that are between * 1.3 the ribs called intercostales we shall intreat of by and by, when wee haue numbred vnto you the parts of the necke.
I do in this place describe the necke, because the chiefe parts therein contayned belong vnto the vitall parts, as the muscles of the voyce, the weazon, the larynx and such like.
It is therefore called Colum a colendo, because we vse to adorne this part with chaines & itwelles. Galen called it 〈 in non-Latin alphabet 〉〈 in non-Latin alphabet 〉 because of the sharpnesse of the bones of it. It is a mid∣dle * 1.4 part betweene the Chest and the head made for the vse of the Chest and the Lungs; long that in the length of it the voice might bee better modulated or tuned, and therefore birds haue the most variety of tunes of any vnreasonable creatures, but fishes because they
