Flashcards in Practical 3 Deck (53):
form bridge of nose.
Cribiform Plate &Crista Galli
cock's comb. Vertical projection, point of attachment for dura matter.
bony plates lateral to crista galli
Blade shaped bone. forms posterior/ inferior nasal septum
paired bones posterior to palatine processes. forms posterior hard palate and part of orbit. meet at median palatine process
Located in the throat above larynx. Horseshoe shaped. Point of attachment for tongue/ neck muscles.
Keystone of cranium. superior orbital fissure,greater/lesser wings, sella turcica, optic fissue (canal)
Superior Orbital Fissures
jagged openings in orbit. provides passage for cranial nerves III, IV, V, and VI.
Larger portion of sphenoid bone exteriorly anterior to temporal. forms part of eye orbit.
Bat shaped portion of sphenoid anterior to sella turcica
Turk's Saddle. saddle shaped region in sphenoid midline.
circular hole through which optic nerve passes.
fingernail sized bone. forms medial orbit walls between maxilla and ethmoid
Point of articulation of parietal bones with the frontal bone
Mid-line articulation point of the two parietal bones
Point of articulation of the temporal bone with the parietal bone.
Point of articulation of the occipital bone and the parietal bones.
Soft stop on top of skull. just forward of center.
soft spot on the back of the skull
24 single bones &2 fused. Makes up vertebral column.
Body of vertebrae
AKA Centrum. Rounded central portion of vertebrae. faces anteriorly in human vertebral column.
soft spot near temporal bone
soft spot between temporal and occipital bones
Opening enclosed by the body and vertebral arch. Passageway for spinal cord.
Two lateral projections from vertebral arch
Single medial and posterior projection from vertebral arch.
connects transverse and spinous processes
protrudes off body to become superior articular facet
Superior Articular Surfaces
Allows for articulation with vertebra above
Inferior Articular Surface
Allows for articulation with vertebra below
Upper most 7 vertebrae. Include axis and atlas
Holes in transverse process in cervical vertebra
C1. No body. Lateral processes contain large concave depressions that receive occipital condyles of skull. "Yes" movement.
C2. Pivot for rotation of axis. "No" movement.
Pivot point for rotation of axis.
12 vertebra below cervical. Articulate with ribs.
Articulate with the head of the rib.
5 below thoracic. Lower back
5 fused vertebra. Below Lumbar.
Articulate with coccyx
Top of sacrum. articulates with lumbar.
Median Sacral Crest
Dorsal side. bumps on midline that would be spinus process if not fused.
Lateral Sacral Crest
Dorsal side. Bumps off midline that would be transverse processes if not fused.
3-5 vertebrae. articulate with sacrum
Uppermost part of sternum. Looks like knot of tie
Point of articulation between the sternum and clavicle
Body of sternum
inferior end of sternum
24. 1-7 true, 8-12 false.
Articulates with costal facets
