(1) Canal-like passageway. (2) Depression or Opening

Sinus

(1) Cavity within a bone, filled with aira and lined with a mucous membrane. (2) Depression or Opening

Groove

(1) Furrow. (2) Depression or Opening

Notch

(1) Indentation at the edge of a structure. (2) Depression or Opening

Tuberosity

(1) Large rounded projection; may be roughened. (2) Projection that is a site of muscle or ligament attachment

Line

(1) Narrow ridge of bone; less prominent than a crest. (2) Projection that is a site of muscle or ligament attachment

(1) Round or oval opening through a bone. (2) Depression or Opening

Condyle

(1) Rounded (knuckle-like) articular projection. (2) Projection that help to form joints

Fossa

(1) Shallow, basinlike depression in a bone, often serving as an articular surface. (2) Depression or Opening
