putamen

 [pu-ta´men]
the larger, darker, and more lateral part of the lentiform nucleus, separated from the lateral globus pallidus by the lateral medullary lamina.

pu·ta·men

(pū-tā'men), [TA]
The outer, larger, and darker gray of the three portions into which the lenticular nucleus is divided by laminae of white fibers; it is connected with the caudate nucleus by bridging bands of gray substance that penetrate the internal capsule. Its histologic structure is similar to that of the caudate nucleus together with which it composes the striatum.
See also: striate body, lenticular nucleus.
[L. that which falls off in pruning, fr. puto, to prune]

putamen

/pu·ta·men/ (pu-ta´men) the larger and more lateral part of the lentiform nucleus.

putamen

putamen

The outer shell of the lentiform nucleus of the BASAL GANGLIA of the brain.

basal ganglia

central nervous system ganglia (i.e. caudate nucleus and putamen [i.e. the striatum], lentiform nucleus and substantia nigra) that control and coordinate fine movement; their output inhibits movement (other than postural reflexes) when at rest, and assists movement initiation by inhibiting postural reflexes

putamen

the larger and more lateral part of the lenticular nucleus.
