temporal muscle

That was why.

And, uh, yesterday I did get a little, like, uh, medical, dental treatment, um, for, like in my masseter and temporalis muscles, and, um, I'm having, like, kind of a wild reaction to it.

Uh, inflammatory you may say.

[laughs] Ugh.

Yes.

So there is a temporalis muzzle that's very active, you know, in patients with migraines.

And there is also the masseter muzzle that takes like a lot of stress when you when you suffer with headaches and migraines, because this is all related, the facial muscles.

Nerve kind of inner weights, like all these temple area, the masseter muscle area and all.

The pain receptors are in the periosteum of the bone.

So when you have these big muscles, the masseter, the temporalis, the internal external pterygoid, the myohyloid, These muscles get tight, they pull on the bone and wherever they're attached to the bone, origin and or insertion is where it's gonna hurt.

And this pain can move around from side to side, from muscle to muscle.

And sometimes patients will come in, they'll show you exactly where the anatomy is.

I mean, the number of times people come in and it hurts right there every morning.

Well, Jessica, what is there? what is right there

now you're telling me you're you're you're insertion you're yeah you're talking you're the temporalis muscle yeah you're the insertion points right there

right there and they're telling you what this disease is all about almost i don't they don't know but anyway so now but if that holding trying to hold the jaw still which you can't right if you continue to brooks you got to eat a couple times a day whatever you're doing you're talking you're on the cell phone You're moving your joint.

They're designed for a developing jaw that basically lacks the massive muscular force of adulthood.

But then, you know, the skull grows, the masseter and temporalis muscles bulk up and the mechanical requirements of the mouth just completely change.

Right.

The arches have to adapt to handle significantly higher occlusal loads.

Now, we're going to look in a moment at the infratemporal fossa, but let's get rid of, first of all, of the temporal fossa.

The temporal fossa is a space beneath the temporalis muscle.

Its roof is the temporalis fascia, and its floor is the surface of the skull at the terion.

Anterolateral to it is the zygoma and the zygomatic process, and it contains the temporalis muscle with the deep temporal arteries and the deep temporal nerves.

If we now turn to the infratemporal fossa, we'll see that this is a much deeper area.

It lies beneath the base of the skull and essentially exists between the lateral pterygoid plate and the mandible, so that its lateral wall is the ramus of the mandible itself with its coronoid process.

Its posterior wall is the carotid sheath and its anterior wall is the posterior part of the maxilla and the inferior orbital fissure.

When the contents of the fossa need to be exposed, we need to remove the coronoid process of the mandible.
