striate body

The caudate and lentiform (lenticular) nuclei; the striate appearance on section is caused by slender fascicles of myelinated fibres. Histologically, the striate body can be subdivided into the generally small-celled striatum, consisting of the caudate nucleus and the outer segment of the lentiform nucleus (the putamen), and a large-celled globus pallidus composed of the two segments.

Synonym: corpus striatum.
