Petrous region, mastoid region, squamous region, and tympanic region
|
|
|
What holes are in the petrous region?

Petrous region, part of the temporal bone; malleus, incus, and stapes (hammer, anvil, and stirrup); internal acoustic meatus
|
|
|
What is the carotid canal, what region is it located in and what bone?
|
Allows the entry of the internal carotid artery.
|
|
|
What is located between the petrous portion of the temporal bone, the sphenoid bone, and the occiptial bone?
|
The foramen lacerum
|
|
|
What is the foramen lacerum located between?
|
the petrous portion of the temporal bone, the spheonoid bone, and the occipital bone
|
|
|
In a living person, is the foramen lacerum open or closed?
|
Closed off by connective tissue
|
|
|
What is just posterior to the carotid canal?
|
The jugular foramen
|
|
|
Where is the jugular foramen located? What is its function of the vein that goes through it?

|
What can easily palpated behind your ear lobe?
|
Mastoid region
|
|
|
What is the mastoid process and what does it do?
|
Bony knob, Serves as an attachment site for the muscles that flex or rotate the head.

|
|
What is mastioditis? How come it can develop?
|
Mastoiditis is an ear infection that spreads to the mastoid air cells. Rather than being solid, each mastoid process is filled with many small, interconnected air cells that communicate with the middle ear.

|
It's about the temporomandibular joint and the pain that is associated with having joint stress due to an uneven bite, or mental stress and structural defomities. AKA phantom pain
