hello all this is dr. Allsop and in this
video we are going to focus on the
muscles of the soft palate there are
five and we will work through some
strategies for identification of these
five so let's get started we will start
with the two that are more superiorly
located and that will most directly
affect the soft palate with contraction
of their muscle fibers and these are the
veli palatini muscles they are guarding
the palate that is what that means and
let's just kind of get our bearings in
terms of where we are at here in the
nasal Concha right here this is going to
be the Taurus two Baris right here and
then this is the opening of or the
Ferengi eloping of the fringo tympanic
tube so we can kind of get an idea of
where we are located right here and just
inferior to these structures you are
going to have the muscle bellies of the
valley palatini muscles that you can see
are heading towards the soft palate so
here's your soft palate this will be the
hard palate right here the levator veli
palatini is the deeper or more medial of
the two but it actually looks
superficial in this view and that makes
sense because we're looking at kind of
on to the internal portions or the more
medial portions of the Hemi sectin head
it has proximal attachments on the
temporal bone as well as the sphenoid
and even there's going to be some
attachments to the fringo tympanic tube
as well and the more distal attachments
or the insertions are going to be on the
soft palate as well as the Palatine
aponeurosis the tensor veli palatini
will originate on the sphenoid and
fringo tympanic tube as well and insert
on the Palatine bone and put in its
tendon will play a big role in terms of
widening and forming a great portion of
the Palatine
sis so let's talk a little bit about the
Palatine aponeurosis
which you can see a little bit of right
here it's going to be this shiny
tendinous portion right in this region
aponeurosis means a widened tendon so it
is mainly formed by the widened tendon
of the tensor veli palatini but it's
important to note that all of these soft
palate muscles have some attachment to
the Palatine aponeurosis so you can
always ID this structure as this
tenderness looking area once the mucosa
has been removed on the posterior border
of the hard palate and here is the hard
palate so we're kind of looking at the
opposite side in this region here's the
soft palate all right in this particular
dissection the mucosa has been removed
for these three remaining muscles and if
there were still mucosa covering these
muscles this would be referred to as the
plateau gloss plateau glassy arch and
this would be the plateau for in GEOSS
arch but the mucosa has been removed so
we're actually looking at the muscle
fibers there and I think the key to
being able to identify these next two is
to really focus on the second part of
the names of these muscles so you're
going to have the plateau glosses is
going to be between the soft palate and
the tongue so here's your tongue here's
the soft palate as we identified so this
will be the pilato glosses whereas the
plateau fringes will extend from the
soft palate to the pharynx and so this
will be your plateau purchase you can
imagine here that if these muscles
contract and shorten they will actually
more greatly affect the more distal
structure so the tongue and the pharynx
and less so in terms of the soft palate
lastly the musculus uvula is a pretty
distinct muscle if you are looking at
muscle on the uvula you are looking at
the musculus you really so it's just
to be any of them those muscle fibers
associated with that and those are the
soft palate muscles five muscles I think
with pretty intuitive names particularly
the these last three that we're looking
at right here please make sure to review
the learning objective videos to better
understand the actions and innovation of
these muscles and as always if after you
review there any lingering questions
please feel free to reach out to me or
my Anatomy colleagues with any questions
thanks for your time and attention
