This muscle seems to continue backwards the semispinalis of the loins. It arises from the last two lumbar spines and from the spines of the sacrum, and it is inserted into the lateral aspect of the coccygeal bones.

It arises from the lower face of the sacrum, beginning about the 3rd foramen. The slips of the inner portion are inserted into the first six coccygeal vertebrte, while the outer portion extends to the extremity of the tail, and is provided with strong tendons of insertion. j^gfjn.
