MARKING
Bone Surface Markings
DESCRIPTION
EXAMPLE
Depressions and Openings: sites allowing passage of soft tissue (nerves, blood vessels,
ligaments, tendons) or formation of joints
Fissure
Narrow slit or groove between adjacent parts Superior orbital fissure of
of bone through which blood vessels, nerves the sphenoid bone
or ligaments pass
Foramen
Opening (hole) through which blood vessels, Foramen magnum
nerves or ligaments pass
Fossa
Shallow depression
Coranoid fossa of humerus
Sulcus
Furrow or groove along a bone surface that
Intertubercular sulcus of the
accommodates a blood vessel, nerve or
humerus
tendon
Meatus
Tube-like opening (passageway)
Ext. auditory meatus of
temporal bone
Processes: Projections or outgrowths on bone that form joints or are attachment points for
connective tissue such as ligaments and tendons.
Processes that form joints
Condyle
Large, round protuberance at the end of a
bone
Facet
Smooth, flat articular surface
Head
Rounded articular projection supported on
the neck (constricted portion) of a bone
Processes that form attachment points for connective tissue
Crest
Prominent ridge or elongated projection
Epicondyle
Projection above a condyle
Linea or line
Spinous process
Long narrow ridge or border (less prominent
than a crest)
Sharp, slender projection
Styloid
Slender pointed process
Trochanter
Very large projection
Tubercle
Small rounded knob-like projection
Tuberosity
Large, rounded usually roughened projection
Suture
Sinus
Fontanel
fovea
Misc Terms
An immovable fibrous joint between skull
bones
A cavity or space within a bone
A membrane covered spot where bone
formation is not yet complete
Tiny pit or depression
Lateral condyle of the femur
Superior facet of a vertebra
Head of the femur
Iliac crest of the hip bone
Medial epicondyle of the
femur
Linea aspera of the femur
Spinous process of a
vertebra
Styloid process of temporal
bone, radius & ulna
Greater trochanter of the
femur
Greater tubercle of the
humerus
Ischial tuberosity of the hip
bone
