00:01
Next, we're gonna look at
the largest salivary
gland, the parotid gland,
as well as the facial
nerves branches.
00:08
And we're looking
at them together
because we're gonna see
that the facial nerve
is very closely related
to the product gland.
00:16
So the parotid gland is
a very descriptive name
because par-otid
means next to the ear,
and we can see the parotid gland
sits very closely to the ear.
00:29
We see that the parotid gland
being pretty far from the
mouth relatively speaking
compared to other
salivary glands,
it's gonna have a long duct
called the parotid duct
in order to reach
the oral cavity.
00:42
That parotid duct
is going to run over
this muscle of mastication or
chewing called the masseter.
00:49
Pass a buccal fat pad,
again, buccal refers to cheek
and then pierce is
one of the muscles
of facial expression
called the Buccinator.
00:59
The one that helps press
food between the two teeth.
01:05
Internally,
it's going to terminate at
a little bump on the inside
of the mouth called
the parotid papilla.
01:13
And that's where it's going
to deliver its salivary fluid.
01:19
Now we have to point out
the parotid gland here
in order to talk
about the facial nerve
because it actually runs
through the parotid gland.
01:27
So we have to fade
away the parotid land
in order to see the facial nerve
which is going to innervate these
muscles of facial expression.
01:38
So if we zoom in,
here, we can see it exiting
the stylomastoid foramen,
that little hole or opening
between the styloid process
and the mastoid process
of the temporal bone.
01:50
There are going to be several
branches of the facial nerve
that are going to go off and supply
all those muscles we talked about
in the muscles of
facial expression.
01:59
There are going to
be temporal branches,
zygomatic branches,
buccal branches,
cervical branches,
posterior auricular
cervical branches,
posterior auricular branches
and all of those names give you
a general idea of the location
that they're going
to and supplying.
