Dr. P here talking about the glossopharyngeal
0:03
or 9th cranial nerve,
0:05
arising from the medulla oblongata.
0:07
Here's 9, 10, and 11 right here.
0:10
And the nerve passes anterolaterally.
0:12
So, let's go down.
0:14
Now, it courses right next to the flocculus,
0:17
part of the flocculo nodular lobe of the cerebellum.
0:20
Here's the flocculus.
0:21
So, you can see the close proximity
0:24
of the glossopharyngeal nerve to the flocculus.
0:26
Here's the glossopharyngeal nerve.
0:27
There's the flocculus right next to it.
0:29
And then we follow it into the region of the jugular fossa,
0:33
which is going to be right here.
0:34
Now, it's difficult to follow contiguously,
0:38
but you see part of it right there.
0:39
And again,
0:40
we're going to talk about nerves 9, 10, and 11 together.
0:43
They're all going into the jugular foramen through
0:46
the central part of the jugular foramen.
0:49
Not as easily seen on this T1-weighted image,
0:52
but it is seen, as it is on this T2-weighted
0:55
cisternographic image.
0:57
Now, as the nerve hits the jugular foramen,
1:00
I want to talk about what happens in here,
1:02
which is very difficult to see anatomically.
1:04
But you've got superior and inferior ganglia in the jugular foramen,
1:08
and they have their own sheath of dura mater.
1:11
The inferior ganglion sits on the inferior surface of the
1:15
petrous part of the temporal bone and is
1:18
related with a triangular depression into which
1:20
the aqueduct of the cochlea actually opens.
1:24
Let's have a look at that anatomic information on CT.
1:28
So on this accompanying CT image,
1:31
you see a triangular shaped space in the region of the
1:34
jugular fossa with the jugular tympanic spine.
1:37
And this is known as the petrosal fossula
1:41
and contains the inferior ganglion of nine.
1:44
