Lecture 2- Skull Flashcards
Mastery
Axial and appendicular skeleton
axial is the trunk and main part
appendicular is the limbs
5 bone classifications
F.I.L.S.S
Flat- thin and curvedfound in axial
Irregular- Axial and complex bones
Long- Appendicular and longer than wide(femur, phalanges)
Sesamoid- locked in tendons and reduces friction on tendon
Short- cube like in appendicular
Diversions of the skull and how many bones in each
Neuro(head) and Viscero(face)
8 in neuro 14 in Viscero
8 skull bones

Skull sutures?
fibrous immovable joints that hold tgth skull bones
coronal suture
Sagittal suture

medial and posterior to eyes
Ethmoid bone
posterior and inferior to the noise
sits on the vomer bone

protrusions-areas of bone that stick out superficially
Articulations-landmarks that fit into one another
Openings-cavities or grooves that allow for tissue to run thru
