Support Structures (Bones)

Frontal Bone

Articulates with parietal, zygomatic, and nasal bones

Parietal Bone

2 pieces; articulates with frontal bone, temporal bone (sides), occipital bone (back)

Occipital Bone

Articulates with temporal, parietal, and atlas of vertebral column

Temporal Bone

Articulates with parietal, occipital, sphenoid, zygomatic, and mandible

Parts of Temporal Bone

Squamous part; Mastoid process; Styloid process; Zygomatic process; External auditory meatus

Ethmoid Bone

perpendicular plate that divides the nasal cavity into left/right

Sphenoid Bone

butterfly shaped; bulk of the floor of the cranial cavity

Mandible

largest, strongest bone of the facial skeleton; unpaired in adult; attachment for muscles of tongue and jaw

5 Parts of Mandible

Body; Ramus; Mental Protuberance; Coronoid Process; Condylar Process

Coronoid Process of Mandible

muscle attachment of mandible

Condylar Process of Mandible

articulates with temporal bone to form the temporomandibular joint (TMJ)

Maxillae

Paired bones (left/right) making up the upper jaw and roof of mouth (hard palate)

4 Processes of Maxillae

Alveolar, Palatine, Frontal, Zygomatic

Nasal Bones

Small and make up the superior nasal surface

Nasal bones articulate with _______ superiorly

…Frontal bones…

Nasal bones articulate with _______ laterally

…Maxillae…

Nasal bones articulate with _______ posteriorly

…Ethmoid bone…

Nasal bones articulate with _______ anteriorly

…Nasal cartilage…

Vomer

unpaired midline bone making up the inferior and posterior nasal septum (divides two nasal cavities)

Zygomatic Bone

lateral part of the face; cheekbones

3 Articulations with Zygomatic Bone

maxilla (anterior); temporal bone (posterior); frontal bone (superior)
