sCranial bones
Frontal bone-above eye sockets Frontal squamous- forehead Supra-orbital notch-where eyebrows would be
Parietal bone-top of head, behind frontal bone
Temporal bone- around ear area, bellow parietal
Squamous- boarders squamous sutures Mandibular fossa- where mandible (chin) connects Zygomatic process- behind check bone Mastoid process- bump behind jaw Styloid process –“twig” Petrous part- inner part of bone, bumpy back part External acoustic meatus- hole behind zygomatic process Internal acoustic meatus- dent not hole in inner part of bone Carotid canal- squiggly line above foramen magnum Foramen lacerum- where cowboy puts feet
Occipital bone- back of head external occipital protuberance- very back bump occipital condyles- crescent shape bumps on either side of foramen magmun foramen magnum- biggest hole in the middle jugular foramen- hole closest to foramen magnum and occipital condyle hypoglossal canals – inside foramen magnum sphenoid bone-looks like winged animal
sphenoid body- middle part sella turcica- saddle shaped part hypophyseal fossa-A depression within the sella turcica lesser wings- smaller wings greater wings- bigger wings optical canals- eye hole ? superior orbital fissure? foramen rotundrum? foramen ovale- tear drop shaped hole foramen spinosum bellow foramen ovale
Ethmoid bone Cribiform plate- Floor of the cranium, Roof of the nasal cavity Middle nasal conchae Olfactory foramina- In the cribriform plate
Cranial sutures Lambdoid suture-“counting lambs”- separating parietal from occipital Coronal suture – “crown” separating frontal from parietal Saggital suture- middle separating parietal bones Squamous suture – above temporal bone
Facial bones
Maxillae-support upper teeth
Orbital rim- under eye
Alverolar process-borders the mouth and supports upper teeth
Palatine process-form the hard palate (roof of mouth)
Infra-orbital(inferior-orbital) foramen- small hone under orbital rim
Palatine bone –back third of roof of mouth
Nasal bone- between eye orbitals
Vomer-line in middle of nose
Inferior nasal conchae-bottom things between vomer
Zygomatic bones- check bone
Temporal process- close to temporal bone
Lacrimal bones- inside eye?
Mandible
Body -jaw
Mental protuberance- chin dimple area
Ramus -ascending from the mandibular angle on either side
Condylar process- after head
Coronoid process- “shark fin”
Mandibular notch- after condylar process
Mental foramen – hole in body
Thoracic cage
Specific cervical vertebrae
Atlas (C1)- first one,
Axis (C2)
Dens part that connects axis and atlas together
Cervical vertebrae (C2 –C7)- does not look lie any animal
Spinous process – part that sticks out, noes
Body-thickest part
Transverse process- make up the side hole
Transverse foramina- side holes
Vertebral foramen – big middle hole
Thoracic vertebrae (T1-T12)- looks like giraffe
Spinous process
Trasverse process
Superior and inferior articular processes
Body
vertebral foramen lumbar vertebrae (L1-L5) spinous process transverse process superior articular process inferior articular process vertebral foramen sacrum medial sacral crest lateral sacral crest sacral canal sacral foramina coccyx ribs head (capitulum) neck body (shaft) sternum mandibular body xiphoid process other to know ???? intervertebral foramen
