Study Notes

Skull Bone Markings and Bones Overview

Sphenoid Bone: Complex base of the skull, resembling a butterfly; has orbital surfaces.
Ethmoid Bone: Contributes to the nasal cavity and eye socket; contains the perpendicular plate.
Lacrimal Bone: Smallest facial bones; located in the medial wall of the orbit, housing the tear duct.
Vomer: Forms part of the nasal septum; contributes to nasal cavity structure.
Maxilla: Two fused bones forming the upper jaw; houses the upper teeth and forms part of the orbit.
Mandible: The lower jawbone; strongest bone of the face; supports lower teeth.
Nasal Bone: Small bones forming the bridge of the nose; contributes to facial shape.
Palatine Bone: Comprises part of the palate, contributing to the oral and nasal cavities.
Zygomatic Bone: Cheekbone; part of the orbit, contributing to the facial structure.
Temporal Bone: Houses structures of the inner ear; involved in jaw movement via the temporomandibular joint.

Specific Features and Markings

Orbital surfaces of the sphenoid and ethmoid bones contribute to the eye's orbit.
Perpendicular Plate of the ethmoid bone forms part of the nasal septum.
Mandibular Angle: Angled point where the body and ramus of the mandible meet, important for jaw structure and function.
Mandibular Condyle: Articulates with the temporal bone at the temporomandibular joint; crucial for movement.
Coronoid Process: Point of muscle attachment on the mandible, aiding in chewing.
Horizontal Plate of the Palatine Bone: Forms the hard palate of the mouth; separates oral and nasal cavities.
Zygomatic Process: Projection of the temporal bone contributing to the cheekbone structure; aids in facial aesthetics and function.
Temporal Process of the Zygomatic Bone: Extension that connects to the temporal bone, forming part of the zygomatic arch.

Anatomy Connections

Inferior Nasal Conchae: Curved bones in the nasal cavity that create turbulence in inhaled air, aiding filtration and warming.
Fontanelles: Soft spots on an infant’s skull that enable growth; anterior and posterior fontanelles are particularly notable.
Maxillae and Palatine Bones: Important for the structure of the mouth and attachment of teeth.

Repeated and Highlighted Structures

Zygomatic Bone: Mentioned multiple times; essential for the structure of the face and eye sockets.
Lacrimal Bone: Frequently referenced due to its role in the tear duct system and the medial wall of the orbit.
Vomer: Critical in nasal septum formation, indicated multiple times emphasizing its anatomical significance.
