Condylar Process, Mandibular Notch, Ramus, Angle, Body, Submandibluar Fossa, Mental foreman, Mandibular Foreman, Coronoid Process.
What is the strongest and only moveable Facial bone?

List all of the Facial bones
Nasal bones, Lacrimal bones, Palatine bones, Inferior Nasal conchea, Vomer, Maxilla, Zygomatic bones, Mandible.
What does the term “Broken Nose” refer to most of the time?
This most of the time refers to the broken Septal Cartilage rather than the Nasal bone itself breaking.
What does the Nasal Septum Consist of?
The 3 components to the nasal septum are:
Vomor
Septal Cartilage
Perpendicular plate of the Ethmoid bone
What are paranasal Sinus?
These are cavities within certain cranial and Facial bones near the nasal cavity.
Lined with mucus membrane that are continuos with the Nasal cavity.
What do the Nasal Bones consist of and what are their purpose?
Small, Flattened, Rectangular shaped that form the bridge of the nose.
Provides muscle attachment and protects the upper nasal cavity.
What is Cleft Palate/lip?
This is a condition that is caused by the The Palatine Process of the Maxilla bone fails to Fuse during growth early in the Fetus.
Another form of this condition called Cleft Lip is a split in the upper lip causing speech problems.
These 2 conditions usually form together.
What do the Lacrimal bones consist of and where are they located?
Thin and flat and resemble a thumbnail in size and shape. Smallest bones in the face.
Posterior-Lateral to the Nasal bones. Help form the medial wall of the orbit.
Contain the Lacrimal Fossa forms with the Maxilla bone and holds the Lacrimal Sac.
What is the Lacrimal Sac?
This helps gather tears and passes them into the Nasal Cavity.
What does the Palatine bone consist of and where is it located in the face?
A pair of L-Shpaed bones
They form part of the posterior of the Hard Palate
Part of the lateral wall and floor of the Nasal Cavity
And a small portion of the Orbits.
The Portion of the Hard Palate is formed by the Horizontal plates of the Palatine Bones.
What Bone forms the Horizontal plates of the Hard Palate?
This is the portion of the Palatine bone called the Horizontal Plates.
What does the Inferior Nasal Conchae consist of and where is it located?
These are separate bones not apart of the Ethmoid Conchae/Bone.
They form part of the inferior-lateral wall of the Nasal cavity and project into the Nasal cavity.
What is the purpose for all of the Nasal conchae in the Nasal Cavity?
The propose for these structures is to swirl the air and filter it before entering the Lungs.
which of the Nasal Conchae is involved in the Sense of smell?
