Lab 2: Self-Exercise Flashcards
which bones contribute to the orbit of the eye (6-7)
sphenoid, frontal, zygomatic, ethmoid, lacrimal, maxilla, palatine
which bones contribute to the brain case (6 named bones, some are paired)
frontal, parietal, occipital, temporal, sphenoid, ethmoid
which bones contribute to the nasal complex (9 named bones, some are paired)
frontal, sphenoid, ethmoid, maxillary, lacrimal, inferior nasal conchae, nasal, palatine, vomer
which bones contribute to the facial part of the skull (8 named bones, some are paired)
maxillae, palatine x2, nasal x2, inferior nasal conchae x2, zygomatic x2, lacrimal x2, vomer, mandible
which bones contribute to the hard palate (2 named bones, but they are paired)
maxilla and palatine
which bones contribute to the oral cavity
mandible, sphenoid, maxillary, palatine
what bones border the anterior (frontal) fontanel in a neonate (4)
frontal x2 and parietal x2
what bones border the posterior (occipital) fontanel in a neonate (3)
parietal x2, occipital
what bones border the mastoid fontanel in a neonate (3)
temporal, parietal, occipital
what bones border the sphenoid fontanel in a neonate (4)
parietal, frontal, temporal, sphenoid
identify the 2 types of bone formation and explain the differences.
endochondral ossification: osteoblasts lay down bone matrix where cartilage was - replaces cartilage
intramembranous ossification: osteoblasts lay down bone matrix between 2 membranes - no cartilage
why is this difference from the previous question so important?
intra - helps heal bone fractures and is fast
endo - lengthens bones
which bones in your body are formed in each manner?
endochondral - most appendicular bones, long bones
intramembranous - flat bones of the skull and mandible
what is the purpose of the paranasal sinuses?
lighten skull bones, produce mucus, resonate during sound production, warm/humidify incoming air
why can’t the carotid canal be seen from a superior view in every case?
the angle and direction of the carotid canal is visibly blocked
