50 Cards in this Set
- Front
- Back
|
Frontal Bone- Superior anterior portion of the skull |
|
|
Parietal Bone- Superior posterior skull portion; connect at the sagittal suture |
|
|
Coronal Suture- Connects the parietal bones and the frontal bone |
|
|
Sagittal Suture- Connects the two parietal bone |
|
|
Squamous Suture- Connects the temporal bone with the parietal bone |
|
|
Lamboid Suture- Connects the occipital bone to the parietal bones |
|
|
Occipitomastoid Suture- Connects the temporal bone to the occipital bone |
|
|
Temporal Bone- Left and Right lateral skull portions inferior to the parietal bone; house the auditory ossicles (six tiny bones) |
|
|
Zygomatic Process- Squamous region of the temporal bone; suture projects outward |
|
|
Mandibular Fossa- Articular depression; only movable joint in the skull, articulates with the mandibular condyles |
|
|
External Acoustic Meatus- Conducts sound waves toward the eardrum |
|
|
Styloid Process- A sharp projection that serves as the attachment site for muscles |
|
|
Mastoid Process- Projection that serves as an attachment site for neck muscles |
|
|
Jugular Foramen- Temporal bone; passage for three cranial nerves and internal jugular vein, takes blood from the brain |
|
|
Carotid Canal- Passage for the internal carotid artery, delivers blood to the brain |
|
|
Internal Acoustic Meatus- Passage for two cranial nerves; mostly filled with hyaline cartilage |
|
|
Foramen Lacerum- Passage for small arteries supplying blood to the inner surface of the cranium |
|
|
Occipital Bone- Forms inferior posterior part of the cranium, most of the skull base |
|
|
Foramen Magnum- Located in the cranial base; allows passage of the spinal cord |
|
|
Occipital Condyle- Rounded projections that connect with the 1st cervical vertebrae to form the atlantooccipital joint; allows us to nod yes |
|
|
External Occipital Protuberance- Small, midline bump at the end of the external occipital crest; at junction between base and posterior wall of the skull |
|
|
Ethmoid Bone- Deeply situated in the skull |
|
|
Crista Galli- Projection of bone; ethmoid bone, helps secure the brain in the cranial cavity |
|
|
Perpendicular Plate- Ethmoid bone, forms the superior portion of the nasal septum |
|
Superior and Middle Nasal Conchae |
Thin scrolls of bone that project into the nasal cavity on either side of the perpendicular plate, slows air (warms/ moistens it) |
|
|
Sphenoid Bone- "Bat shaped," posterior to the frontal bone, connects with every other cranial bone ("key stone" bone) |
|
|
Pterygoid Process- Projects from the greater wings and serve as an attachment site for muscles |
|
|
Superior Orbital Fissure- Slit or crack in the greater wing of the sphenoid bone, passage for cranial nerves |
|
|
Sella Turcica- Saddle shaped area in the midline of the sphenoid bone containing hypophyseal fossa which houses the pituitary gland |
|
|
Hypophyseal Fossa- "seat of the saddle" houses the pituitary gland |
|
|
Optic Canal- Openings at the base of the lesser wings that serve as passageways for the optic nerves |
|
|
Foramen Ovale- oval shaped, posterior to sella turcica |
|
|
Mandible- Lower jawbone, connects with the temporal bones at the mandibular fossa; forms only movable skull joints |
|
|
Mandibular Condyle- Rounded projections that connect with the mandibular fossa to form the temporomandibular joint |
|
|
Maxillae- Forms the upper jawbone, "keystone" bones of the face because it connects with all the other bones except mandible |
|
|
Alveolar Process- Inferior border of maxillae, contains the tooth |
|
|
Infraorbital Foramen- Opening below the orbits |
|
|
Palatine Bone- With the palatine processes, forms the hard palate (roof of the mouth) |
|
|
Zygomatic Bone- Lateral to the eye sockets (orbits) form the lateral rims of the orbits |
|
|
Lacrimal Bone- The smallest bones in the skull, located in the medial portion of each orbit |
|
|
Lacrimal Fossa- Deep groove; contains a lacrimal sac- collects tears and drains the fluid into the nasal cavity |
|
|
Vomer- Forms the inferior portion of the nasal septum |
|
|
Inferior Nasal Concha- Paired bones that project medially to form the lower, lateral walls of the nasal cavity |
|
|
Nasal Bone- Form the bridge of the bone |
|
Cervical Vertebrae Body |

Cervical Vertebral Foramen |
Triangular |
|
Cervical Vertebral Spinous Process |
Short, bifid (forked); projects directly posteriorly |
|
Cervical Vertebral Transverse Foramen |
