1. sphere.
2. a spherical structure.
globus hyste´ricus the subjective sensation of a lump in the throat.
globus pal´lidus the smaller and more medial part of the lentiform nucleus of the brain; it is divided into two parts, lateral and medial, by the medial medullary lamina.

glo·bus pal·'li·dus

[TA]
the inner and lighter gray portion of the lentiform nucleus; composed of a lateral segment (globus pallidus lateralis [TA]) and a medial segment (globus pallidus medialis [TA]) separated by a vertically oriented lamina of fibers, the lamina medullaris medialis [TA] (medial medullary lamina [TA]). The medial segment may also be incompletely divided into a lateral part [TA] (pars laterallis [TA]) and a medial part [TA] (pars medialis [TA]) by the accessory medullary lamina [TA] (lamina medullaris accessoria [TA]).
