This muscle arises from the transverse processes of the seventh, eighth, ninth, and tenth dorsal vertebrae, by as many distinct tendons, which soon grow fleshy; and then again become tendinous, and are inserted into the spinous processes of the sixth or seventh uppermost dorsal, and two lowest cervical vertebrae, by as many tendons. Its action is, to extend the spine obliquely backwards.
