|
Coronal suture |
Where parietal bones meet frontal bone anteriorly |
|
|
Sagittal suture |
Where parietal bones meet superiorly at cranial midline |
|
|
Lambdoid suture |
Where parietal bones meet occipital bones posteriorly |
|
|
Squamous suture |
Where parietal bone and temporal bone meet on the lateral aspect of the skull |
|
|
Mandible |
Lower jawbone, largest strongest bone of face Forms chin and two upright rami Alveolar process- where teeth are embedded Mandibular symphysis- where two mandibular bones fused together |
|
|
Mandibular foramina |
Permit the nerves responsible for tooth sensation to pass to teeth in lower jaw |
|
|
Mental foramina (mandible) |
Openings that allow blood vessels and nerves to pass to the skin of chin |
|
|
Maxillary bones
|
Fused, form upper jaw and central portion of facial skeleton Palatine process- forms 2/3 of roof of mouth Incisive canal- passageway for blood vessels and nerves
|
|
|
Frontal processes (maxillary) |
Extend superiorly to the frontal bone Forms part of lateral aspects of bridge of nose |
|
|
Maxillary sinuses |
Largest paranasal sinuses Extend from orbits to roots of upper teeth |
|
|
Inferior orbital fissure (maxillary) |
Deep within the orbit Permits zygomatic nerve, the maxillary nerve, and blood vessels to pass through face |
|
|
Infraorbital foramen (maxillary) |
Allows the infraorbital nerve and artery to reach the face |
|
|
Zygomatic bones |
Cheekbones |
|
|
Nasal bones |
Fused medially, forming bridge of nose |
|
|
Lacrimal bones |
Fingernail-shaped, contribute to the walls of orbits Lacrimal fossa- allows tears to drain from eyes |
|
|
Palatine bones |
Horizontal plate- complete posterior portion of hard palate Perpendicular plate- form part of nasal cavity and small part of orbit walls 3 articular processes- pyramidal, sphenoidal, orbital |
|
|
Vomer |
Lies in nasal, forms parts of nasal septum |
|
|
Inferior Nasal Conchae |
Thin, curved bones that project medially from lateral walls of nasal cavity |
|
|
Axial skeleton |
Skull, vertebral column, and thoracic cage |
|
|
Hyoid bone |
Lies in anterior neck just inferior to mandible Only bone that does not articulate with any other bone Helps for swallowing |
|
|
Typical vertebra |
Oval body- wider from side to side Spinous process- projects directly back, is bifid Vertebral foramen- large, triangular |
|
|
Intervertebral foramina |
Notches on superior and inferior border, provides lateral openings between adjacent vertebrae Spinal nerves pass through here |
|
|
Atlas |
First vertebrae, has no body or spinous process Its a ring of bone with arches and lateral mass on each side Allow you to say yes |
|
|
Axis |
2nd vertebrae, has a body and other typical features Dens- act as pivot for rotation of atlas, allows for you to nod no |
|
|
Sternum |
Fusion of manubrium, the body, and xiphoid process Clavicular notches- articulates with clavicles and first two pairs of ribs |
|
|
Jugular notch (sternum) |
Central notch indentation |
|
|
Sternal angle |
Where the manubrium joins sternal body |
|
|
Xiphisternal joint |
Point where the sternal body and xiphoid process fuse Lies at level of ninth thoracic vertebra |
|
|
Paranasal sinuses |
Frontal, sphenoid, ethmoid, and maxillary |
|
|
Cervical |
Small oval body Triangular large foramen Contain foramina Superior facets directed superposteriorly Inferior facets directed infernoanteriorly |
