| Question | Answer |
|---|---|
| Superior to the Orbit, Anterior to the brain | Frontal bone |
| Inferior to the Parietal and Connected by the Lamboidal suture, contains the Foramen Magnum | Occipital bone (aak·si·puh·tl) |
| The Keystone bone, Posterior to the Orbit, anterior to the Occipital, Inferior to the Frontal | Sphenoid bone (Sfee-Noyd) |
| Medial to both Orbits, posterior to the Nasal, separates the nasal cavity from the brain | Ethmoid (eth·moyd) |
| Posterior to the Frontal, Superior to the Temporal, Split by the Sagittal suture | Parietal (pr·ai·uh·tl) |
| Posterior to the Sphenoid, Inferior to the Parietal and connected by the Squamosal suture | Temporal |
| Inferior to the Maxilla, The lower Jaw bone | Mandible |
| Inferior to the Ethmoid, Superior to the Roof of the mouth | Vomer |
| Lateral to the Nasal, half of the inferior part of the orbit, the Upper Jaw | Maxilla |
| Lateral to the Maxilla in the orbit, The cheek bone | Zygomatic |
| Part the medial wall of the orbit, sits anterior to the Superior Optical Fissure and posterior to the maxilla | Lacrimal |
| Medial to the maxilla, Inferior to the Frontal, superior to the Anterior Nasal Aperture | Nasal |
| Posterior to the Maxilla, Medial from the rear Molars, The Back of the roof of the mouth | Palatine (pa·luh·tine) |
| Medial to the maxilla, inferior to the Nasal, Located in the Posterior to the Anterior Nasal Aperture | Nasal Concha |
| The Suture that connects the Frontal and the parietal | Coronal |
| The suture that splits the Parietal | Sagittal |
| The suture that Connects the Parietal and Temporal | Squamos |
| The suture that connects the Parietal and Occipital | Lambdoid |
| Name the four Paranasal Sinuses | Frontal Sinus Sphenoid Sinus Maxilla Sinus Ethmoid Sinus |
| What is the function of a Sinus? | Add moisture and heat to the air we breath Help fight Infection Reduce weight of skull |
| Part of the Temporal Bone, extending downward and forward from the undersurface of the temporal bone | Styloid Process |
| Connects the Temporal to the Zygomatic Bone | Zygomantic Process of the Temporal |
| Posterior Part of the Temporal bone, Inferior to the parietal bone, Gives attachment to various muscles | Mastoid process |

| Inferior to the orbit, lateral to the anterior Nasal Aperture on both sides | Infraorbital Foramen |
| Inferior to the Teeth, Located on both sides of the mandible | Mental Foramen |
| Medial to the Superior Orbital Fissure, Located In the Sphenoid bone | Optic Canals |
| Located in the Posterior of the Sphenoid bone, Allows Passage of the mandibular nerve, One of the larger of the holes | Foramen Ovale |
| Posterior to the Foramen Ovale, anterior and lateral to the Foramen Magnum | Carotid Canal |
| Formed by the temporal bone anteriorly and the occipital bone posteriorly, its directly posterior to the carotid canal | Jugular foramen |
| the soft spot on the babies head, allows for the babies head to fit through the birth canal and allows rapid growth of the brain | Fontanelles |
| Protrusion on each side of the foramen Magnum | Occipital Condyles |
| extended from Zygomantic Process of the Temporal, connects the process to the Zygomantic bone | Zygomantic arch |
| Bony eye socket | Orbit |
| Saddle shaped depression on the Superior side of the Sphenoid. | Sella turcica (seh·luh tur·kuh·kuh) |
| wedge shaped vertical line on the Superior Side of the Ethmoid bone, Posterior to the Nasal | Crista Galli (kri·stuh ga·lee) |
| Directly Inferior to the Crista Galli, Posterior to the nasal, | Cribiform Plates |
| Outer ear canal | External Acostic meatus |
| Formed by the Palatine Process and the palatine | Hard Palate |
