styloid process
the styloglossus and stylohyoid muscles originates here
acromion
this marking articulates with the clavicle
concha
a part that resembles a shell
articulation
the region where adjacent bones contact each other - a joint.
Tuberosity
Large rounded projection; may be roughened
sulcus
groove in the bone (sigmoid sulcus)
Shallow, basinlike depression in a bone, often serving as an articular surface
Fossa
transverse foramina
the vertebral arteries pass through these foramina

articular process
a projection that contacts an adjacent bone
Space within a bone, filled with air and lined with mucous membrane
Sinus
ischial tuberosity
this marking is the "sit bone"; it also is the origin site for the biceps femoris semitendinosis, and semimembranosis

Meatus/canal
A passageway through the bone
Sharp, slender, often pointed projection
Spine
scaphoid
this carpal articulates with the radius and is the carpal most often broken
What is a Process?
Any bony prominence.
skull misc. markings

-cribriform plate
 
Fossae
depression or cavity in the bone
head
bony expansion carried on a narrow neck
lateral epicondyl
the supinator, extensor carpi ulnaris, and the extensor digitorum muscles originate here
acetabulum
this marking on the coxal bone articulates with the femur
What is a Ramus?
Armlike bar of bone.
Narrow ridge of bone; Less prominent than a crest
Line
xiphoid process
the diaphragm originates here and the rectus abdominis muscle inserts here
wing
a structure resembling the wing of a bird
top (right & left) halves of skull
parietal bone
DEPRESSIONS AND OPENINGS FOR NERVES OR BLOOD ( MEATUS )
CANAL -LIKE PASSAGWAY
fovea capitis
marking is the attachment site of the capitate ligament
corocoid fossa
this marking is the origin site of the biceps brachii muscle
What is an Epicondyle?
Raised area on or above a condyle.

temporal (j) foramen
jugular foramen
Armlike bar of bone
Ramus
arch
a curved or bowlike outline
What is the Meatus?
Canal-like passageway.
Small rounded projection or process
Tubercle
manubrium
the clavicle articulates with this portion of the sternum
ethmoid sinuses
these structures produce mucus, lighten the skull and serve as a resonating chamber for sound
line
narrow less prominent ridge of bone
What is a Fissure?
Narrow, slitlike opening.
lumbar (vertebral column)
largest size (triangular hole)
Narrow ridge of bone; usually prominent
Crest
cribriform plate
the olfactory nerves pass through these foramina
eminence
a slightly raised area above the surrounding surface
What is a sharp, slender, often pointed projection?
Spine
 Head
The expanded end of the epiphysis. Articulates with adjacent bone.
trapezium
carpal forms the saddle joint with the first metacarpal
What is a Tubercole?
Small, rounded projection or process.
A line remaining after two bones have joined together and fused
Suture
lateral malleolus
this marking is what you call your ankle bone on the lateral side of your leg
What is the Crest?
Narrow ridge of bone; usually prominent.
petrous portion
the middle and inner ear are housed by this portion of the temporal bone
What is a Sinus?
Cavity within a bone, filled with air and lines with mucous membrane.
