Bones and Skeletal Tissue

meatus

(depressions and openings allowing blood vessels and nerves to pass) canal-like passageway

sinus

(depressions and openings allowing blood vessels and nerves to pass) cavity within a bone, filled with air and lined with mucous membrane

groove

(depressions and openings allowing blood vessels and nerves to pass) furrow

fissure

(depressions and openings allowing blood vessels and nerves to pass) narrow, slitlike opening

foramen

(depressions and openings allowing blood vessels and nerves to pass) round or oval opening through a bone

fossa

(depressions and openings allowing blood vessels and nerves to pass) shallow, basinlike depression in a bone, often serving as an articular surface

process

(projections that are sites of muscle and ligament attachment) any bony prominence

tuberosity

(projections that are sites of muscle and ligament attachment) large rounded projection; may be roughened

line

(projections that are sites of muscle and ligament attachment) narrow ridge of bone; less prominent than a crest

crest

(projections that are sites of muscle and ligament attachment) narrow ridges of bone; usually prominent

epicondyle

(projections that are sites of muscle and ligament attachment) raised area on or above a condyle

spine

(projections that are sites of muscle and ligament attachment) sharp, slender, often pointed projection

tubercle

(projections that are sites of muscle and ligament attachment) small rounded projection or process

trochanter

(projections that are sites of muscle and ligament attachment) very large, blunt, irregularly shaped process (The only examples are on the femur)

ramus

(projections that help to form joints) armilke bar of bone

head

(projections that help to form joints) bony expansion carried on a narrow neck

condyle

(projections that help to form joints) rounded articular projection

facet

(projections that help to form joints) smooth, nearly flat articular surface
