Also, there is insertion by an aponeurosis anterior to M. adductor mandibular posterior as stated above.
It is covered by an aponeurosis, and in part by the great gluteal.
Anterior to the acetabulum the origin is aponeurotic, and the edge of this aponeurosis passes over the proximal end of the femur.
Fibers attach to the dorsal and ventral side of the aponeurosis.
Part of the aponeurosis becomes tendonlike in the middle of M. pterygoideus ventralis and separates its two divisions.
The aponeurosis is the same that gives origin to the fibers of pars lateralis.
In the pig, and especially in the horse, it passes further upwards, to arise from the aponeurosis of the coccygeal muscles.
The lateral tendon of M. pseudotemporalis superficialis converges with the aponeurosis.
All of the fibers of the muscle insert on the posteroventral surface of the aponeurosis before it divides.
The aponeurosis extends about three-fifths of the distance along the muscle and it is dorsal or superficial to all of the fibers.
aponeurosis ap·o·neu·ro·sis (āp'ə-nu-rō'sĭs, -nyu-)
A sheetlike fibrous membrane resembling a flattened tendon that serves as a fascia to bind muscles together or to connect muscle to bone.
