test2 ch 7 Flashcards
frontal bone
anterior portion of the cranium and roof of orbits
supraorbital foramen provie passage for blood vessels that supply the eyebrow, eyelid, and frontal sinuses;
frontal sinuses
coronal suture
parietal bone
form part of the superior and lateral surface of the cranium; sagital and squamous sutures
occipital bone
the posterior and inferior surface of cranium;
occipital condyle- site of articulation b/t skull and atlas
foramen magnum- hole for spinal cord
lamboidal suture
temporal bone
part of lateral walls of cranium and zygomatic arches; only articulation with the mandible;
mastoid process- attachment point for muscles that rotate and extend the head
zygomatic process-cheekbone
styloid process- support hyoid bone
external auditory meatus- ear hole
jugular foramen
caratoid canal
sphenoid bone
floor of cranium, crossbrace sella turcica-turkish saddle hypophyseal fossa- holds pituitary gland greater wing sphenoid sinus
ethmoid bone
anteriomedial floor of the cranium, roof of nasal cavity, part of nasal septum and medial orbital wall crista galli cribiform plate perpendicular plate ethmoid sinus
zygomatic-F
rim and lateral wall of the orbit and part of zygomatic arch
maxilla-F
upper teeth and inferior orbital rim, most of hard palate
palatine process-hard palate
maxillary sinus
mandible
lower jaw mandibular condyle- articulation point w mandibular fossa of temporal bone body coronoid process- closes the jaws ramus-ascending part of jaw angle
lacrimal-F
small bones that are part of the medial orbit between the maxilla and ethmoid
nasal
bridge of nose
palatine
paired bones form posterior hard palate and part of orbit
vomer
posterior and inferior nasal septum
inferior nasal concha
thin curved bones of nasal cavity
eye orbit
frontal, maxilla, lacriminal, ethmoid, palatine, zygomatic, sphenoid
vertebral columns
7 cervical, 12 thoracic, 5 lumbar
primary curves
thoracic and sacral
secondary curves
lumbar and cervical
cervical vertebrae
atlas-holds head, lacks body and spinous process w large foramen
axis- “no”
thoracic vertebrae
heart shaped body
lumbar vertebrae
large body, no costal facets
body
transfers weight along axis
vertebral foramen
opening enclosed by the body and vertebral arch for spinal cord
spinous process
single medial and posterior projection
transverse foramen
cervical only, notches in pedicles
transverse process
2 lateral projections
vertebral arch
composed of pedicles, laminae, and a spinous process
articular process
articulations w other vertebrae
sternum
manubrium, body (gladiolus), xiphoid process
