Dr. P here to talk about the spinal accessory
0:04
or accessory nerve, nerve number eleven.
0:06
It's a cranial nerve that supplies the
0:09
sternocleidomastoid and trapezius muscles,
0:11
and it's considered the 11th of twelve
0:13
pairs of cranial nerves.
0:15
It was formerly believed to originate in the brain,
0:18
but that's no longer really accepted dogma.
0:21
As you know,
0:21
the sternocleidomastoid muscle
0:23
tilts and rotates the head,
0:24
while the trapezius muscle connected to the
0:26
scapula acts in shoulder shrugging.
0:29
So here we have an axial image level of the pyramid
0:33
and restiform body.
0:34
That's a vessel right there.
0:36
There's your glossopharyngeal nerve right there.
0:39
Here is your vagus nerve.
0:41
And right behind that,
0:42
this little reit, or complex posteriorly,
0:46
the third of these three nerves,
0:48
A, B and C, right there,
0:51
is the lowermost portion of the spinal accessory nerve.
0:55
Now, the spinal accessory nerve
0:57
has traditional descriptions that divide it up
1:00
into a spinal part and a cranial part.
1:03
The cranial component rapidly joins the vagus nerve,
1:06
so there's some debate about whether the cranial part
1:09
should actually be considered part
1:11
of the spinal accessory nerve.
1:13
And we're going to get into those two
1:15
major contributions, one up higher,
1:17
one down lower in the sagittal projection,
1:20
in the next vignette.
