QuestionAnswer
skull composed of two sets of boes: cranial bones and facial bones. All skull bones except the mandible are joined by immovable interlocking articulations called sutures
frontal bone forms forehead and superior portion of orbit
parietal bone forms a large portion of the lateral and superior aspect of the cranium on each side
temporal bone inferior to parietal bone
external auditory meatus external ear passageway leading to eardrum
mastoid process rounded eminence on the inferior surface, just posterior to the external auditory meatus, serves as attachment site for neck muscles
styloid process slende process extending downward from bottom of temporal bone. Attachment site for throat and neck muscles
zygomatic process slender process extending forward from the temporal bone. Forms part of the zygomatic arch
mandibular fossa oval shaped depression located just anterior to the external auditory meatus. Articulates with a condyle on the lower jaw to form the teporomandibular joint.
shenoid connected to frontal bone anteriorly and temporal bone posterioly. Forms part of the lateral side of the cranium and part of the posterior surface of the orbit
occipital bone forms posterior, inferior portion of the cranium
foramen magnum large hole in infeior surface. serves as a passageway for the spinal cord as it passes through the cranium to connect to the brain
occipital condyles rounded eminences located on each side of the foramen magnum. Articulate with fossae on the first cervical vertebra, the atlas
coronal suture between frontal bone and each parietal bone
sagittal where parietal bones meet at the midline
squamosal junction between inferior border of the parietal bone and superior border of the sphenoid and temporal bones
lambdoidal joins occipital bone to both parietal bones
wormian bones small islets of bone formed within a suture. most commonly found within the lambdoidal suture
frontanels the fetal skull at birth contains unossified membranous areas called frontanels, which allow compression of the skull during delivery.
Ethmoid bone forms a small portion of the anterior cranial floor, roof of the nasal cavity, upper portion of the nasal septum and part of the medial aspect of the orbit
crista galli vertical projectio. serves as point of attachment for the dura matter (outermost membrane covering the brain
cribiform plate lateral to the crista gall. Contains numerous holes for passage of olfactory nerves between the nasal cavity and the brain
occipital bone forms posterior portion of cranial floor. Contains foramen magnum
maxilla upper jaw
palatine bones unite at midline to form posterior 1/3 of hard palate
zygomatic bone cheek bone
temporal process long, slender process of temporal bone that fuses with the maxilla to form the zygomatic arch
vomer forms the inferior portion of the nasal septum. Aticulates with the perpendicular plate superiorly and hard palate inferiorly
inferior nasal canchae scroll shaped plates of bone protruding from lateral, inferior walls of the nasal cavity
mandible lower jaw.
hypid bone horse-shoe shaped bone inferior to the mandible.
centrum (body) load-bearing portion
vertebral foramen large hole in the center for passage of the spinal cord
transverse processes lateral projections. serve as attachment site for muscles
spinous process posterior projection. Serves as attachment for muscles
lamina portion between transverse and spinous process
pedicle portion between centrum and tranverse process
superior and inferior articular facets surfaces where vertebrea articulate with other vertebrae
sternum breastbone. composed of 3 bones fused together: manubrium, gladiolous and xiphoid process
sternal extremity flattened end. articulates with sternum
vertebral extremity end that articulates with thoracic vertebrae
head enlarged terminal portion of the vertebral extremity. articulates with centrum of thoracic vertebrae
tubercle small bump near head. articulates with the costal facet on the transverse process of a thoracic vertebrae
neck portion between head and tubercle
costal groove groove on inner, inferior edge
