tubercle
small rounded projection
horn
a pointed projection
ethmoid (cg)
crista galli
ulna
-olecranon process
-coronoid process
-trochlear notch
-radial notch
-styloid process
fossa
hollow or depressed area-scapula
margin
an edge or boreder
axial skeleton (spine)
vertebral column
curve
a bend with no angle
PROCESS
ANY BONY PROMINENCE (ANY BONE)
Sharp, slender, often pointed projection
Spine
pterygoid process
the pterygoid muscles originate here
Head
bony expantion or a narrow neck
CONDYLE
ROUNDED KNOB THAT ARTICULATES WITH ANOTHER BONE
condoyle
large, convex articular surface (may have special names)
Shallow, basinlike depression in a bone, often serving as an articular surface
Fossa
trapezium
this carpal forms the saddle joint with the first metacarpal
internal auditory meatus
the vestibulocochlear nerve passes through this foramen
Foramen
round or oval opening through a bone
tubercule
a nodule or small, rough, rounded eminence
SULCUS
GROOVE FOR TENDON, NERVE OR BLOOD VESSEL
iliac crest
marking is what your belt rests on
Sinus
space within a bone, filled with air, and lined with mucus membrane
What is Tuberosity?
Large, rounded Projection; may be roughened.
mandibular foramen
blood vessels and nerves to the lower teeth pass through this foramen
line, ridge
a long, thin projection, often with a rough surface
What is a narrow ridge of a bone that is less prominent?
Line
DEPPRESSIONS AND OPENINGS FOR NERVES OR BLOOD ( FOSSA)
SHALLOW BASINLIKE DEPRESSION IN A BONE OFTEN SERVING AS AN ARTICULAR SURFACE
Ethmoid
Conchae
border
the boundary line
Frontal bone
frontal sinus
temporal (m) process
mastoid process
facet
small, slightly depressed,articular surface
crest
narrow prominent ridge of bone
sphenoid sinuses
these structures produce mucus, lighten the skull and serve as a resonating chamber for sound
gluteal tuberosity
gluteus maxmus muscle inserts here
canal
a narrow tubular passage or channel
cervical (vertebral column)
small size (3 holes)
Skeletal elements derived from embryonic gill arches. They include the hyoid bones and ear ossicles
Visceral Skeleton
Narrow ridge of bone; usually prominent
Crest
talus
this tarsal bone articulates with the tibia and fibula
foramen ovale
the mandibular branch of the trigeminal nerve passes through this foramen
optic foramen
the optic nerve passes through this foramen
What is the round or oval opening through a bone?
Foramen
external occipital protuberance
the attachment site for the nuchal ligaments (ligament nuchae)
Ramus
An extension of the bone at an angle to the rest of the structure
What is a line?
Narrow ridge of bone; less prominent than a crest.
FACET ( PROJECTION THAT HALP MAKE UP A JOINT
