The =serratus anticus= is inserted into the fifth to the eighth ribs
inclusive, the serratus posticus into the last four or five ribs. There
are usually no digitations attached to the ninth and tenth ribs.
The =transversalis costarum= (Iliocostalis) extends to the wing of the
atlas.
The =spinalis et semispinalis= can be separated without much difficulty
from the longissimus dorsi, the division from the common mass of the
loins beginning about the first lumbar vertebra.
The =multifidus= resembles that of the horse.
=Interspinales= are present, as well as distinct =intertransversales= of
the back and loins.
