Inferior Parietal Lobule
HIDEInteractive Transcript
0:01
Let's talk about the superior and inferior parietal lobule,
0:04
especially the inferior parietal lobule.
0:06
Just to get you oriented,
0:08
here's your staircase descending precentral sulcus,
0:12
which means this has to be the precentral gyrus,
0:15
which means that is the central sulcus.
0:17
That is the subcentral sulcus.
0:19
Remember, these two,
0:20
the Sylvian fissure and the central sulcus,
0:23
don't communicate.
0:23
And there is the post-central sulcus.
0:26
There's a method to my madness
0:27
because the postcentral sulcus becomes this structure,
0:33
an arcuate shape or horseshoe-shaped structure
0:36
called the intraparietal sulcus.
0:38
Sometimes I use the term interparietal,
0:41
which is actually technically incorrect,
0:43
so forgive me if I do.
0:44
The intraparietal sulcus.
0:47
Above that is going to be the superior parietal lobule.
0:49
Below it, the inferior parietal lobule.
0:51
So, let's say it again one more time.
0:53
I know you're listening on tape,
0:56
so you can review it again.
0:57
But there is the postcentral sulcus.
1:00
Central sulcus.
1:01
Postcentral sulcus is the upswing of this arcuate shape,
1:05
there it is again,
1:06
this arcuate-shaped intraparietal sulcus.
1:09
The intraparietal sulcus separates the superior parietal
1:12
lobule from the inferior parietal lobule.
1:14
What's in the inferior parietal lobule?
1:16
Well, right above the Sylvian fissure,
1:18
supermarginal gyrus,
1:20
right above the superior temporal sulcus?
1:23
The angular gyrus.
1:25
Inferior parietal lobule.
1:26
You got it.
