We remember, that the trapezius of man is partly inserted into the clavicle, and the disappearance of this latter cannot fail to bring modifications in the general disposition of the corresponding portion of the muscle.

When the trapezius acts as a whole the scapula is raised.
It is visible in the space limited by the trapeziusand the mastoido-humeral, the direction of which it crosses obliquely.
The cervical portion occupies, in the region of the neck, an area relatively smaller than the corresponding portion of the trapezius in man.
In the pig and in ruminants, in which the trapezius approaches more closely to the head, the mastoido-humeral occupies, in consequence, a less extent of the cervical region.
The trapezius in man similarly arises in part from the clavicle; for the reasons above indicated its clavicular fasciculi cannot exist in distinct form in the animals which have no clavicle.

Bradford inserts a portion of the trapezius into the humeral insertion of the deltoid.
The muscles most frequently at fault are the sterno-mastoid and trapezius of one side, and the posterior rotators of the opposite side.
The trapezius is markedly wasted, and is, therefore, less prominent in the neck than normally, and the functions of the arm and shoulder are impaired, especially in making overhead movements.

The first wound was slight; the second a deep flesh-wound over the trapezius muscle; the third extended from the right sterno-cleido-mastoid midway upward to the middle of the jaw and down to the rapine of the trachea.
The neck flap of the wound fell away from the muscular structures beneath it, exposing the trapezius muscle almost one-half the distance to the shoulder blade.
If the sternomastoid and homolateral trapezius are acting together, torsion of the neck is very pronounced and the skin over that area is deeply lined.
It may happen that the head is rotated and inclined to the same side, as in Grasset's case, where the curious combination occurred of clonic convulsion of left trapezius and pectoralis major with right pectoralis major and sternomastoid.
Fournier[144] has seen a case of convulsive twitching of the right sternomastoid and trapezius arrested when the head was reclining on a pillow.

The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "trapezius" in a variety of sentences. We hope that you will now be able to make sentences using this word.
