| Question | Answer |
|---|---|
| Name the bones of the Skull | Frontal, lateral/medial Parietal and Temporal, Occipital, Sphenoid, Ethmoid |
| Frontal bone structures/holes | Supraorbital Foramen Glabella |
| Temporal Bone structures/holes | Zygomatic Process, mandibular fossa, External Auditory Meatus, Mastoid Process, Styloid process, jugular foramen, carotid foramen/canal, Internal acoustic meatus |
| Occipital Bone structures/holes | Occipital Condyle, Foramen Magnum |
| Sphenoid Bone structures/holes | Sella Turcica, optic foramina, Lesser wing, Superior orbital fissure, Greater Wing, foramen ovale |
| Ethmoid bone structures/holes | crista galli, cribiform plates, olfactory foramina |
| Maxilla structures/holes | infraorbital foramen, palatine processes, incisive foramen |
| Mandible structures/holes | mandibular symphysis, mental foramina, body, angle, rami, mandibular condyle, mandibular notch, coronoid process, alveoli (margins around teeth) |
| paired bone posterior to palatine processes | palatine bone |
| zygomatic process connects the temporal bone to this facial bone... | zygomatic bone |
| This bone is located in throat above larynx. Serves as point of attachment for many tongue and neck muscles | hyoid bone |
| Blade shaped bone in median plane of nasal cavity; forms posterior and inferior nasal septum | vomer |
| bone medial to either maxilla directly inferior to the glabella | Nasal Bone |
| Bones that are to either side of the sagittal suture? | Parietal bones |
| What suture divides the parietal and temporal bones? | The squamous suture |
| What suture divides the parietal and occipital bones? | lamboid suture |
| What suture divides the frontal bone from the parietal bones? | Coronal suture |
| What are the curved bones protruding medially form the lateral walls of the nasal cavity? | inferior nasal conchae |
| What is the name of the fingernail sized bones forming a part of the medial orbit walls b/w maxilla (more superficial) and the ethmoid (deeper in reference to this bone)? | lacrimal bone |
| What are the 8 identifying areas on the Atlas of the cervical vertebrae? | posterior tubercle, posterior arch, transverse process, *transverse foramen*, anterior tuburcle, *inferior articular facet*,superior articular facet, vertebral foramen |
| Remembering trick of the atlas | Face lying prone (inferior view): face with widely spaced eyes(inferior articular facet). Chin(posterior tubercle), Cheeks(Posterior arch), Ears(Transverse Processes) with the canals(transverse foramen), Top of head(anterior arch), vertebral foramen |
| 8 Identifying marks of the Axis? | Odontoid Process, Body, Superior articular facet, transverse process, transverse foramen, spinous process, inferior articular facet, vertebral foramen |
| Cervical vertebrae difference | transverse foramen* |
| Thoracic vertebrae difference | rib facet* |
| Similarities b/w vertebrae | -spinous process, -vertebral foramen, -superior/inferior articular process -superior/inferior articular facet -body -transverse process |
| Lumbar vertebrae difference | no transverse foramen or rib facet |
| Sacrum (5 fused vertebrae) | Sacral canal sacral promentory posterior sacral foramina median sacral crest |
| description of where the 4 defining characteristics of the sacrum can be found. | sacrum: sacral canal viewed fr the superior posterior angle with multiple posterior sacral foramina linearly arranged on either side of the median sacral crest. On the anterior side,the most superior portion of the sacrum is called the sacral promentory. |
| Name the bone that has (3-5 fused vertebrae) | Coccyx |
| Sternum | -jugular notch -clavicular notch -manubrium -sternal angle -body -xiphoid process |
| Ribs | -costal cartilage -false rib -tubercle -head -floating rib -shaft -true rib -neck |
| Which ribs are considered true? # to # | Ribs 1-7 |
| Which ribs are considered false ribs? # to # | Ribs 8-12 |
