THE CORTEX - MODULE Flashcards
Major sulci are given ____
names i.e. Central Sulcus q
Large sulci are called ____
fissures i.e. lateral fissure
Gyri are named based on…
their function and/or their location
The lobes of the brain are named after…
the bones of the skull
The ___ lobe is not a discrete lobe
limbic
It spans portions of the frontal, parietal, and temporal lobes
What are primary cortical areas
areas that receive information from peripheral receptors, with little interpretation of the meaning of information
Primary cortical areas are concerned with….
receiving sensory information and executing motor tasks
What are association areas
Areas that receive input from the primary area and are involved in higher order processing, integrating, and interpreting information
Where are association areas located
adjacent to primary areas
Association areas can be classified as either…
unimodal or heteromodal
Outflow from the primary motor areas makes up the _____
corticospinal tract
Where does the supplementary motor area lie
anterior to the primary motor cortex and superior to the premotor area
What is found in the supplementary motor area
Motor maps for postures
What is the role of the premotor association area
involved in higher order processing and integration of motor information
Where is the somatosensory association area located
adjacent to the primary somatosensory area in the parietal lobe
What is the role of the somatosensory association area
Interpretation of the significance of sensory information, such as touch, pressure, and proprioception
Where is the primary visual cortex found
located on the banks of the calcarine sulcus on the medial aspect of the occipital lobe
How is the primary visual cortex organized
retinotopically
Fibers from the upper visual field project to the…
lower bank of the calcarine sulcus
Fibers from the lower visual field project to the…
superior bank of the calcarine sulcus
where is the fovea represented
near the occipital pole
Where is the visual association area found
surrounding the primary visual cortex on the medial surface of the occipital lobe
What does the visual association area do
give meaning and interpretation to visual information
Where are the frontal eye fields located
in the supplementary motor area and extend anteriorly
