Bones of the Skull

Page 2: Bones of the Skull. Frontal Forehead Superior eye orbits Frontal sinus Inferior connection –Zygomatic process –Temporal bone

Frontal

• Forehead

• Superior eye orbits

• Frontal sinus

• Inferior connection– Zygomatic process– Temporal bone

Page 3: Bones of the Skull. Frontal Forehead Superior eye orbits Frontal sinus Inferior connection –Zygomatic process –Temporal bone

Parietal

• Paired bones

• Anterior – Frontal– Coronal Suture

• Middle – Sagittal Suture

• Inferior – Temporal

• Posterior – Occipital– Lambdoid Suture

Page 4: Bones of the Skull. Frontal Forehead Superior eye orbits Frontal sinus Inferior connection –Zygomatic process –Temporal bone

Temporal

• Paired bones

• Articulates with:– Zygomatic process– Parietal bones– Mandible

• Processes:– Mastoid– Styloid

Page 5: Bones of the Skull. Frontal Forehead Superior eye orbits Frontal sinus Inferior connection –Zygomatic process –Temporal bone

Occipital

• Foramen Magnum

• Occipital Condyles

Page 6: Bones of the Skull. Frontal Forehead Superior eye orbits Frontal sinus Inferior connection –Zygomatic process –Temporal bone

Sphenoid

• Greater Wing - Foramen Rotundum– Cranial Nerve V

• Lesser Wing – optic foramen– CN II foramen passage

• Sphenoid sinus

Page 7: Bones of the Skull. Frontal Forehead Superior eye orbits Frontal sinus Inferior connection –Zygomatic process –Temporal bone

Ethmoid

• Mid-Sagittal

• Cribriform Plates – Cranial Nerve I

Page 8: Bones of the Skull. Frontal Forehead Superior eye orbits Frontal sinus Inferior connection –Zygomatic process –Temporal bone

Lacrimal

• Smallest facial bone

• Medial wall of the eye orbit

Page 9: Bones of the Skull. Frontal Forehead Superior eye orbits Frontal sinus Inferior connection –Zygomatic process –Temporal bone

Nasal

• Bridge of the nose

• Articulates with:– Mandible

Page 10: Bones of the Skull. Frontal Forehead Superior eye orbits Frontal sinus Inferior connection –Zygomatic process –Temporal bone

Zygomatic

• Cheek bones

• Processes:– Frontal– Marginal– Temporal– Maxillary

Page 11: Bones of the Skull. Frontal Forehead Superior eye orbits Frontal sinus Inferior connection –Zygomatic process –Temporal bone

Maxillae

• Upper Jaw – Alveolar Process– Upper teeth

• Inferior Eye Orbit

• Maxillary Sinus

• Zygomatic Process

• Palatine Portion– Anterior portion of the hard palate

Page 12: Bones of the Skull. Frontal Forehead Superior eye orbits Frontal sinus Inferior connection –Zygomatic process –Temporal bone

Palatine

• Posterior ½ of the hard palate

Page 13: Bones of the Skull. Frontal Forehead Superior eye orbits Frontal sinus Inferior connection –Zygomatic process –Temporal bone

Mandible

• Lower Jaw

• Alveolar process – teeth

• Articulates with:– Temporal (TMJ)– Maxillae

Page 14: Bones of the Skull. Frontal Forehead Superior eye orbits Frontal sinus Inferior connection –Zygomatic process –Temporal bone

Vomer

• Forms part of the nasal septum

• Articulates with:– Maxillae– Palatines– Ethmoid– Sphenoid
