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
