Terms in this set (34)
The term basal ganglia refers to a collection of ----- cell bodies (ganglia) located at the base of the ----- hemispheres (basal).
However, this term is somewhat misleading since the nuclei included in the basal ganglia are located deep within the cerebral hemispheres, in the -----, and in the -----.
These nuclei are the caudate nucleus, putamen, ----- pallidus, ---- nucleus, and substantia nigra. All are ----- structures.
globus; subthalamic; bilateral
consists of the caudate nucleus and the lentiform nucleus.
t consists of putamen and caudate nucleus.
Neostriatum or striatum:
It consists of putamen and the globus pallidus. Globus pallidus is medial to putamen. GP is divided into external and internal parts by a lamina of nerve fibers.
Globus pallidus is ----- to putamen. GP is divided into external and internal parts by a ---- of nerve fibers.
The lentiform nucleus is bounded laterally by a thin layer of ---- matter that constitutes the ---- capsule.
The extreme capsule separates the claustrum from the ----.
The medial surface of ---- nucleus lies against ---- capsule.
It consists of an ---- portion or head which then tapers into a slender tail extending backward and then forward into the ---- lobe.
The caudate nucleus tail terminates at the ----- body.
The head of the caudate nucleus bulges into the frontal horn of the ----- ventricle.
The first part of the tail lies along the ----- margin of the central part of the ventricle.
receives fibers from the cerebral cortex, thalamus, and substantia nigra.
