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)

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
