Bones and Sutures of the cranium Flashcards
bones that house and protect the brain and structures associated with the inner ear
bones of the cranium
bones located more anteriorly and surround the orbital and nasal cavities, giving shape to the face
bones of the face
frontal bone
most anterior bone
occipital bone
most posterior bone
parietal bones
most superior bones
temporal bones
most lateral bones
sphenoid bone
anterior to temporal bones
coronal/frontal suture
between frontal and parietal bones
sagittal suture
between left and right parietal bones
lambdoidal suture
between occipital bone and parietal/temporal bones
squamosal suture
between temporal bones and sphenoid/parietal bones
fontanelles
soft spots in infant skull
metopic suture
separates frontal bone in 2 in infancy
temporal lines
lines in parietal bones
anterior cranial fossa
internal side of the frontal bone
occipital condyles
form atlanto-occipital joint with concave facets of the atlas
nuchal lines
where neck muscles attach
posterior cranial fossa
internal side of occipital bone
zygomatic process
superior and anterior to meatus, forms zygomatic arch with zygomatic bone
zygomatic arch
formed by zygomatic bone and zygomatic process
styloid process
attachment point for several muscles and ligaments
mastoid process
muscle attachment site
glenoid (mandibular) fossa
between styloid process and zygomatic process, articulates with condyle of mandible
temporomandibular joint
formed by glenoid fossa and condyle of mandible
parts of the sphenoid bone
greater and lesser wings, lateral and medial pterygoid plates
