Basal Ganglia Flashcards
Components of the basal ganglia
Caudate Putamen Globus pallidus Substantia innominata Subthalamic nucleus Substantia nigra Nucleus acumbens
Striatum and lenticular nucleus
Most important/high yield portions of basal ganglia
Striatum - Caudate + putamen
Lenticular nucleus- Globus pallidus + putamen
Dorsal basal nucleus consists of
Caudate nucleus
Putamen
Globus pallidus
Ventral striatum consists of
Nucleus acumbens
Olfactory nucleus
Ventral palladium consists of
Substantia innominata
Striatal complex consists of
Caudate nucleus
Putamen
Nucleus acumbens
Olfactory tubercle
Palladial complex consists of
Globus pallidus
Substantia innominata
Paleostriatum consists of
Globus pallidus
Input to basal ganglia is done by which nuclei
Striatal complex minus olfactory tubercle
Caudate nucleus
Putamen
Nucleus accumbens
Output from basal ganglia is done by which nuclei
Globus pallidus - internal segment - limb/trunk control
Ventral pallidum - output part - motions
Substantia nigria- cognition/eye movements
Skeletomotor loop
Primary motor/supplementary motor area–>
Putamen–>
Globus pallidus/substantia nigra–>
Ventral anterior/ventral lateral thalamic nuclei
