Names of bone markings exercise 9 figure 9.1

suture

- The line of union in an immovable articulation (as between the bones of the skull); also : such an articulation - a strand or fiber used to sew parts of the living body

Others Sinus

Bone cavity, filled with air and lined with mucous membrane Cavity within a bone Cavity

Projections that are sites of muscle and ligament attachment Line

Narrow ridge of bone; less prominent then a crest

Projections that are sites of muscle and ligament attachment crest

Narrow ridge of bone; usually prominent

Depressions and Openings for Passages of Blood Vessels and Nerves Fissure

Narrow, slitlike opening

Others Fossa

Shallow basinlike depression in a bone, often serving as an articular surface. A shallow depression (the word suggests "ditch" or "trench"). Such depressions in the surface of bones often receive another articulating bone with which a joint is formed. (Shallow) depression

Projections that are sites of muscle and ligament attachment Trochanter

Very large blunt, irregularly shaped process (the only examples are on the femur) Large blunt bump-like projection (larger than a tuberosity, which is in turn larger than a tubercle) Process - attach connective tissues

Projections that are sites of muscle and ligament attachment Process

any bony prominence raised area or projection Process - attach connective tissues

Projections That Help Form Joints Ramus

armlike bar of bone Curved portion of a bone, like a ram's horn. Curved surface

Projections That Help Form Joints Head

bony expansion carried on a narrow neck

Others Meatus

canal like passageway A tube-like opening or channel extending within a bone. Channel through bone

Irregular Bones

do not fall in the three bone categories (vertebrae)

trochlea

fully-shaped part of structure a bony structure through which a tendon passes with which other structures articulate

Flat Bones

generally thing, two wafer like layers of compact bones sandwiching a layer of spongy bone, many are curved (skull bones)

Depressions and Openings for Passages of Blood Vessels and Nerves Notch

indentation at the edge of a structure A V-like depression in the margin or edge of a flat area Articulatory surface

Projections that are sites of muscle and ligament attachment tuberosity

large rounded projection; may be roughened Process - attach connective tissues

Long bone

much longer than they are wide (femur phalanges(finger bones)) normally have shaft with heads at either end, composed predominantly of compact bone.

Projections that are sites of muscle and ligament attachment Epicondyle

raised area on or above a condyle Bump near a condyle; often give appearance of a "bump on a bump"; for muscle attachment Process - attach connective tissues

Depressions and Openings for Passages of Blood Vessels and Nerves Foreman

round or oval opening through a bone Round hole through which blood vessels, nerves or ligaments pass. Hole

Projections That Help Form Joints Condyle

rounded articular projection Rounded bump or large rounded prominence. Such rounded surfaces usually fit into a fossa on another bone to form a joint. Process - forms joints

Projections that are sites of muscle and ligament attachment Spine

sharp, slender, often pointed projection

Projections that are sites of muscle and ligament attachment Tubercle

small rounded projections or process small tuberosity that may also be described as a round nodule or warty outgrowth. Process - attach connective tissues; can also form articular surfaces

Projections That Help Form Joints Facet

smooth, nearly flat articular surface 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). Articular part (ends) of long bones.

Short Bones

typically cubed shaped, contain more spongy bone than compact bone (tarsal, carpal)

Depressions and Openings for Passages of Blood Vessels and Nerves Groove

Furrow, a narrow, linear hollow or depression.
