3.4.2 Flashcards
Sensory Association Cortex
Those
regions of the cerebral cortex that receive
information from the regions of the primary sensory cortex.
Primary Motor Cortex
The region of the
posterior frontal lobe that contains neurons that control movements of skeletal
muscles
Motor Association cortex
The region
of the frontal lobe rostral to the primary
motor cortex; also known as the premotor
cortex
Prefrontal Cortex
The region of the
frontal lobe rostral to the motor association cortex
Corpus callosum
A
large bundle of axons that interconnects
corresponding regions of the association
cortex on each side of the brain.
Limbic cortex
Phylogenetically old cortex, located at the medial edge (“ limbus”) of the cerebral hemispheres; part of the limbic system.
Cingulate Gyrus
A strip of
limbic cortex lying along the lateral walls
of the groove separating the cerebral hemispheres, just above the corpus callosum
Limbic system
A group of brain regions
including the anterior thalamic nuclei,
amygdala, hippocampus, limbic cortex,
and parts of the hypothalamus, as well as
their interconnecting fiber bundles.
Hippocampus
A forebrain structure of
the temporal lobe, constituting an important part of the limbic system.
Amygdala
A structure in the
interior of the rostral temporal lobe, containing a set of nuclei; part of the limbic system.
Fornix
A fiber bundle that connects the
hippocampus with other parts of the brain,
including the mammillary bodies of the
hypothalamus; part of the limbic system
Mammillary Bodies
A protrusion of the bottom of the brain at
the posterior end of the hypothalamus,
containing some hypothalamic nuclei;
part of the limbic system
Basal Ganglia
A group of subcortical
nuclei in the telencephalon, the caudate
nucleus, the globus pallidus, and the putamen; important parts of the motor system
Nucleus
An identifiable
group of neural cell bodies in the central
nervous system.
Diencephalon
A
region of the forebrain surrounding the
third ventricle; includes the thalamus and
the hypothalamus
