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
