Bone Markings Flashcards
angle
A corner
Body
The main portion of a bone
The diaphysis of long bones such as the humerus.
Condyle
Rounded bump or large rounded prominence. Such rounded surfaces usually fit into a fossa on another bone to form a joint.
Process - forms joints
Crest
Moderately raised and therefore prominent border or ridge. Such crests are often sites for a muscle attachment.
Process - attach connective tissues
Diaphysis
Shaft (main section) of a long-bone
The long straight sections of e.g. the humerus, fibula, tibia and femur.
Epicondyle
Bump near a condyle; often give appearance of a “bump on a bump”; for muscle attachment.
Process - attach connective tissues
Epiphysis
The end part of a long bone which usually has a larger diameter than the shaft-part of the bone (which is called the diaphysis).
Facet
A smooth flat articular surface. Such flat surfaces may form a joint with another facet or flat bone.
Process - forms joints
Fissure
Long, crack-line hole for blood vessels and nerves.
Channel-like cleft or crack
Foramen
Round hole through which blood vessels, nerves or ligaments pass.
Fossa
A shallow depression (the word suggests “ditch” or “trench”).
Head
A rounded projection that forms part of a joint.
Process - forms joints
Line
Similar to a crest but not raised as much - may be relatively faint
Margin
Edge of a flat bone or flat portion of the edge of a flat area
Meatus
A tube-like opening or channel extending within a bone.
Channel through bone
Neck
A section of bone (esp. of long bones) between the “head” and the “shaft” of the bone, the “neck” of a bone is a narrowed portion, usually located at the base of the “head” of the bone.
Notch
A V-like depression in the margin or edge of a flat area
Articulatory surface
Process
A raised area or projection.
Process - attach connective tissues
Ramus
Curved portion of a bone, like a ram’s horn.
Curved surface
Sinus
Cavity within a bone
Spine or
Spinous process
Similar to a crest but raised higher; a sharp, pointed, slender projection. Such sharp raised projections called spines are often sites for muscle attachment.
Process - attach connective tissues
Trochanter
Large blunt bump-like projection (larger than a tuberosity, which is in turn larger than a tubercle).
Process - attach connective tissues
Tuberosity
Large rounded or oblong projection that may look like a raised bump.
Such rounded/oblong projections called tuberosities are often sites for muscle attachment.
Process - attach connective tissues
Tubercle
Small tuberosity that may also be described as a round nodule or warty outgrowth.
Process - attach connective tissues; can also form articular surfaces
