Chap. 6. Of the Muscles of the Neck▪
THe Muscles of the Neck are on each side four. The two first extend, the two others do bend the same.
I. The two LONG ONES lye hid under the Oeso∣phagus or Gullet, arising from the first Vertebra of the Chest, with a beginning fleshy and sharp, they ascend into the extuberant Process of the first Vertebra, with an acute tendon, and sometimes are inserted into the Occiput, near its great Hole.
Its Use is, to bend the Neck right forwards and the Head withal: and if but one act, it turns it on the one side.
The SCALENI so called, which some count Muscles of the Chest, have a peculiar Hole, through which Veins and Arteries enter into the Arms. They arise fleshy, at the side of the Neck, from the first Rib; they are inserted inwardly into all the Vertebra's for the most part of the Neck, and especially into their trans∣verse Processes.
III. The TRANSVERSALES duo, seated in the back, do rise from the six Vertebra's of the Chest which are uppermost and outmost: they are inserted externally into all the transverse Processes of the Vertebra's of the Neck. And between these Nerves go out. Their Use is, to extend or to bend backwards, but if one act alone, to move obliquely.
IV. The two SPINATI possess the whole Neck be∣tween the Spinae, and are long and large. They arise from five Spines of the Vertebra's of the Neck, and seven of the Chest. They are strongly implanted into the whole lower part of the Spine of the second Verte∣bra. Their Use is the same as of the third pare.
