The Skull

• Occipital Bone
• Interparietal Bone
• Parietal Bones
• Temporal Bones
• Frontal Bones
• Ethmoid
• Sphenoid

• Occipital Bone- CaudoVentral portion or cranium
• Interpariatel Bones - Dorsal portion between Occipital/Parietal Bones
• Parietal Bone-Dorsal Lateral Portion of skull.
• Frontal Bone- RostroLateral Portion of skull.
• Temporal Bone- VentroLateral Portion of skull.
• Sphenoid Bone- Ventral portion of the skull.
• Ethmoid Bone- Is Rostral to sphenoid bone

The Frontal Bones and the zygomatic bones 

Frontal Bones contain frontal sinuses

The Foramen Magnum is the large opening located on the Occipital Bone. Its it where the Spinal Chord exists the skull

Occipital Condyles are found in the Occipital Bone where they form a joint w/ the Atlas 

(Atlas-1st Cervical Vertebra)

Temporal bones contain the External Acustic Meatus Opening, leads to the middle/inner ear cavities

• The Temporal Bone forms PORTION of the Zygomatic Arch.
•             AND
• The Temporo-Mandibular Joint W/ the Mandible.

The Bulla is an egg shaped swelling on the Ventral Surface, containing the middle ear structure.

• The External Face Bones are: 
• Nasal
• Incisive/Premaxilla
• Zygomatic/Zygomatic Arch
• Maxilla
• Palantine
• Bulla
• Mandible

The incisive Bone is made up of the 2  most rostral skull Bones.

It houses Incisor Teeth/Dental pad

• The Nasal Bone is composed of 2 Bones 
• located in the dorsal part of the nasal cavity, forming the bridge of nose.

• The Maxillary Bone is  made of 2 bones, located as the majority of the upper Jaw.
• Houses upper Canine Teeth/Premolar Teeth.
• Contains Maxillary Sinuses.
• Forms PORTION of hard palate.

The Maxillary Bone Houses Canine & Pre molar teeth

The lacrimal Bone is made up of 2 SMALL bones. Located in part of the eye orbit.

contains lacrimal sacs (Part of Tear Draining System)

The Zygomatic Bone is made of 2 bones. Just below and behind eyes. forming Portion of eye orbit.

The Zygomatic Arch is the widest Bone in the skull . Easily palpated on each side just below nd behind the eyes

The Mandible Bone is made of 2 bones united Rostrally by Mandibular Synthesis. It forms the lower jaw.

The Mandible Bone is Composed of the shaft (Horizantal Part) and the Ramus (Verticle Part)

The shaft is the Horizantal part of the Mandible Bone. It is attached to the Ramus by Mandibular Synthesis and houses all lower teeth

The Ramus is part of the verticle part of the Mandible Bone attached to the shaft by mandibular synthesis. Its claudal end forms Temporamadibular joint w/ Temporal bone.

Powerful jaw muscles attach at the Ramus

The Internal Bones of the face is/are Turbinates

Turbinates are thin scroll like bones that fill majority of the space in the nasal cavity.

Turbinates play an important role in "conditioning air".

• The Sphenoid Bone is made of 2 bones.
• Located on the ventral portion of the skull.

contains Pituitary Fossa and Sphenoid Sinus

The Ethmoid bone is a single bone located on rostral to the Sphenoid Bone.

It contains Cribriform Plate as well as ethmoidal sinus

The Cribriform plate is located in the Ethmoid bone, where olfactory nerves pass through the upper portion of the nasal cavity into the brain, (sense of smell)
