Facet
Head
Condyle articulating surface
Large smooth rounded oval structure
Facet articulating surface
Small, flat, shallow surface
Head articulating surface
Prominent, rounded, epiphysis
Three types of depressions
Alveolus, fossa, sulcus
Alveolus depressions
Deep pit or socket in the maxillae or mandible
Fossa depressions
Flattened or shallow depression
Sulcus depressions
Narrow grove
9 types of projections
Crest, epicondyle, line, process, Ramus, spine, trochanter, tubercle, tuberosity
Crest projection
Narrow, prominent, ridgelike projections
Epicondyle projections
Projection adjacent to condyle
Line projection
Low ridge
Process projection
Any marked bony prominence
Ramus projection

Spine projection
Pointed, slender process
Trochanter projection
Massive, rough projection found only on the femur
Tubercle projection
Small, round projection
Tuberosity projection
Large, rough projection
5 types of openings
Canal, fissure, foramen, meatus, sinus
Canal opening
