Crest
Narrow ridge of bone; usually prominent
Trochanter
Very large, blunt, irregularly shaped process (only example is femur)
Line
Narrow ridge of bone *less prominent then a crest
Tubercle
Small rounded projection or process
Epicondyle
Raised area on or above a condyle
Spine
Sharp, slender, often pointed projection
Process
Any bone prominence
Head
Bony expansion carried on a narrow neck
Facet
Smooth, nearly flat articulate surface
Condyle
Rounded articulate projection
Ramus
Armlike bar of bone
Groove
Furrow
Fissure
Narrow, slitlike opening
Foramen
Round or oval opening through a bone
Notch
Indentation at the edge of a structure
Meatus
Canal-like passageway
Sinus

Long bones
Longer than they are wide
Ex. Humerus, femur, radius, ulna, metacarpals, phalanges
Short bones
Cube shaped; about equal in length and width
Ex. Carpals, tarsals

Thin, flat
Ex. Bones of the cranium, sternum, ribs, scapulae
Sutural bones
Small flat bones located within the sutures of cranial bones
Ex. Where the fontanels existed in the baby
Irregular bones
Complex shapes
Ex. Vertebrae, facial bones, vocal bones, calcaneus
Sesamoid bones
Develops within tendons, protect and increase mechanical effect of tendon by changing the direction of pull
Ex. Patellar of knee, pisiform of the carpal
Tuberous it’s
