naming bones Flashcards
condyle
knuckle-like, smooth, rounded articular surface - carpals (condyloid), elbow (hinge)
facet
two flat surfaces, smooth nearly flat articulated surface - vertebrae (amphiarthroses), tarsals (gliding)
head
rounded, enlarged rounded end of bone - only on humerus and femur (ball and socket)
crest
narrow ridge of bone - iliac crest, articular crests
epicondyle
above and outside condyles, bony bulge above a condyle - distal end of humerus
process
any projection on bone, oft pointed and sharp - mastoid process, styloid process of ulna
spine
sharp, slender projection - spinous process of vertebrae, spine of scapula
trochanter
large, blunt irregular projections - only on femur, greater and lesser
tubercle
small, rounded, knob-like projection -greater and lesser on humerus
tuberosity
larger, rounded knob-like projection - on tibia
fissure
long, narrow cleft or slit - superior orbital fissure
foramen
rounded, opening thru a bone, foramen magnum
frontal bone
forehead
sinus
open cavity in bone - in nasal passage way
meatus
tunnel - external to internal acoustic meatus
fossa
smooth, shallow depression - supraspinous fossa of scapula, pituitary fossa
parietal bones
behind coronal suture, on either side of sagittal suture
bregma
point where coronal and sagittal sutures meet
lambda
point where sagittal and lambdoidal sutures meet
occipital bone
beneath lambdoidal suture
temporal bone
weakest bones in skull, behind frontal bone on either side
zygomatic arch
on outside of temporal bone
external occipital protuberance
bump on the bottom of the skull
parietal eminences
bumps on either parietal bone
