Wherefore when the first oblique moves the head obliquely forwards, the se∣cond puls it packe by the first Vertebra, this with his associate of the other side, may be truly termed the proper muscles of the neck, because they belong to no other part; whereas it is contrary in other muscles. But we must note, that the head (according to Galens opinion) hath two motions, one directly forwards and backwards, as ap∣peares in beckning it forwards; and casting it backwards; the other circular.
The first in Galens opinion is performed by the first Vertebra moved upon the second; the second by the head moved upon the first Vertebra; for which he is reproved by the latter Anatomists, who teach that the head cannot be turned round or circularly upon the first Vertebra without putting it out of joynt.
For the last, which bends the head, it ascends from the upper and side part of the Sternon, and the next part of the clavicle, obliquely to the Apophysis

Mastoides or mammillary processe of the hinde part of the head, whence it is called the
Mastoideus. You may divide this by reason of its manifold originall rather into two, than into three muscles. But it had beene better that the head might have beene moved every way, equally backwards and to the right and left sides; but thus it would often have beene strained to our great dammage and danger of life; neither could there have beene such facility of motion without a loosensse of the joynt. Therefore nature had rather bestow upon the head an harmelesse facultie of fewer motions, than one furnished with more variety, but with a great deale more uncertainty and danger. Wherefore it hath made this juncture not laxe or loose, but stiffe and strong.
