It has been customary to divide the obturator complex into two parts--an obturator internus and an obturator externus; the latter has often been further subdivided.
Usage of the term obturator internusis avoided because the muscle so named is considered not to be homologous with the mammalian muscle of the same name; the entire obturator complex is called M.
Applying these terms to Coccyzus, pars postica is equivalent to the entire obturator internus of Berger (1952).
Their obturator externus lies anterior and deep to the extrapelvic part of the obturator internus and inserts separately from the latter.
Therefore, the term obturator internus is inappropriate for the avian muscle and must be abandoned.
It appears to me that the dorsal part and a part of the ventral part of the obturator externus of Berger correspond to the extrapelvic fleshy part of the obturator internus of Hudson, et al.
The evidence is conclusive, it seems to me, that the obturator internusof Hudson is not homologous with the mammalian obturator internus.
He states that the former is homologous with the mammalian obturator internus and the latter with the obturator externus.
Furthermore, as in the case of the latter, the vastus externus and the vastus internus take their origin from the shaft of the femur, while the long portion arises from the pelvis.
We also partly see there, in these animals, the vastus internus and the rectus of the triceps (see Fig.
The two fasciculi then pass towards the knee, being in relation with the rectus and the vastus internus of the triceps.
The disorders to which the young are more peculiarly liable afford a presumption, that hydrocephalus internus is an inflammatory disease; and this is confirmed by the regularity of the period, within which it finishes its course.
If the meninges of the brain sympathize with other torpid parts, or are primarily affected, delirium, stupor, and perhaps hydrocephalus internus occur, see Class II.
He had convulsion fits two days preceding his death, and the well-known symptoms of hydrocephalus internus all made their appearance.
In nervous fever the pain of the head generally affects the middle of the forehead; in hydrocephalus internusit is generally on one side of the head.
The hydrocephalus internus is distinguished from apoplexy by its being attended with fever, and from nervous fever by the paroxysms being very irregular, with perfect intermissions many times in a day.
The head, thus brought to bear upon the lower and back part of the capsule, tears it and leaves the socket, passing upwards and coming to rest on the dorsum of the ilium, above and anterior to the tendon of the obturator internus (Fig.
Note relation of neck of femur to tendons of obturatorinternus and gemelli (diagrammatic).
As in strabotomy we cannot get at the obliques, it seems all the more desirable to offer them stronger resistance by greater tension of the internus by means of advancement.
I shortened the abducens (without touching the internus again).
In permanent divergent squint we shall have, as a rule, to combine shortening of the internus of the squinting eye with tenotomy of both externi, even if the convergent movement is still possible to a slight degree.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "internus" in a variety of sentences. We hope that you will now be able to make sentences using this word.
