axial skeleton Flashcards
what made up the axial skeleton and appendicular skeleton
Axial (skull, vertebral column, & thoracic cage)
- Appendicular (UE, LE, Pelvic Girdle)
name the fossa of the skull

parietal and frontal
which bone make the lambdoidal suture
parietal and occipital
which bone formsposterior wall and floor of cranium
occipital
which bone make the squamosal suture
temporal and parietal
what form the sphenoid bone in cranium
Forms lower lat. wall of cranium, part of floor of cranium and post wall of orbit

what forms the vertical plate of palatine
help form lateral wall of nasal cavity
where is located the nasal bone
Join at midline to form bridge of nose between orbits
where is located the lacrimal bone in comparison with the maxilla and nasal
Posterior and lateral to nasal and maxillary bones
