The Parietal Lobe
What are the three functional areas of the parietal lobe
- Primary somatosensory cortex - Wernicke's area (inferior parietal lobule) - The rest (super specific, right?)
What is on the medial side of the parietal lobe?
- posterior paracentral lobule (extension of the postcentral gyrus) - precuneus
Where is the primary somatosensory cortex located?
Postcentral gyrus
What are the three areas of the parietal lobe on the lateral side?
Postcentral gyrus Superior Parietal Lobule Inferior Parietal Lobule
Where is the postcentral gyrus
Posterior to the central sulcus and parallel to it. It extends to the postcentral sulcus
The precuneus is an "extension" of what?
Superior Parietal Lobule
What does the intraparietal sulcus demarcate?
The superior and inferior parietal lobules
How many areas is the parietal lobe divided into?
Three
What is the function of the remainder of the parietal lobe?
complex aspects of spatial orientation and directing attention
Where is Wernicke's area located?
inferior parietal lobule and parts of temporal lobe
What is the function of the primary somatosensory cortex?
intitial cortical processing of tactile and proprioceptive information
Where is the supramarginal gyrus located?
it caps the upturned end of the lateral sulcus
Where is the intraparietal sulcus?
it runs posteriorly from the postcentral sulcus toward the occipital lobe
What is the function of wernicke's area?
language comprehension
The precentral and postcentral gyri can be collectively referred to as what?
paracentral lobule - partly in the frontal lobe and partly in the parietal lobe
What does the angular gyrus cap?
superior temporal gyrus
What is the inferior parietal lobule composed of?
supramarginal gyrus and angular gyrus
