In the 2010 census, for example, 94% of the U.S. population selected at least one of the five standard, government-defined racial categories â white, black, Asian, American Indian or Pacific Islander. Federal policy defines âHispanicâ not as a race, but as an ethnicity. And it prescribes that Hispanics can in fact be of any race. But these census findings suggest that standard U.S. racial categories might either be confusing or not provide relevant options for Hispanics to describe their racial identity.
A pupil-involving third-nerve palsy may be an unusual presentation of im-pending carotid occlusion. Baker LJ, Galetta SL, Yousem DM, Golden MA, Asbury AK. Pupil-involving third-nerve palsy and carotid stenosis: rapid recovery following endarterectomy.
Fourth cranial nerve palsy is a condition that causes weakness or paralysis to the superior oblique muscle.his condition often causes vertical or near vertical double vision as the weakened muscle prevents the eyes from moving in the same direction together. Because the fourth cranial nerve is the thinnest and has the longest intracranial course of the cranial nerves, it is particularly vulnerable to traumatic injury.
