Cerebrum - LectureCapture Flashcards
Diencephalon contains what 2 structures?
Thalamus and hypothalamus
Telencephalon contains what 2 structures?
Cerebral cortex and subcortical regions
Cerebrum develops from the
Prosencephalon
Which structure grows to surround the other in development of the cerebrum?
Telencephalon surrounds the diencephalon
What is important about the cerebral cortex in relation to gyri and sulci?
Although there are gyri and sulci, the cerebrum remains one continuous sheet
What structure lies at the floor of the lateral fissure?
Insular lobe
Where is the amygdala located?
Medial temporal lobe
What region of cortex is the first to receive sensory input for any modality?
Primary sensory cortex (AKA postcentral gyrus)
What structure is the primary sensory cortex?
Postcentral gyrus
What is the primary motor cortex? (what is located there?)
UMNs for parts of the corticospinal and corticonuclear systems
What structure is the primary motor cortex?
Precentral gyrus
Frontal eye fields contain what?
UMN for CN 3,4,6
What is the purpose of the secondary association cortex?
To process complex information (to and from primary cortices)
What is the purpose of the tertiary association cortex?
To allow multiple sensory or motor systems to come together (like Wernicke’s area)
Visual input that is complex goes where to be processed?
From primary visual cortex to visual association cortex
Thalamocortical neurons (pathway and input)
Go from thalamus to cortex, have somatosensory input and motor input (cerebrocerebellar)
