depressions or openings

fissure, foramen, fossa, fovea, meatus, sinus, sulcus

process

projection or prominence

ramus

branch or extension of a bone

neck

a narrowing of a long bone

condyle

smooth articular protuberance

facet

small, nearly flat articular surface

what is the difference between the anatomical neck and the surgical neck

anatomical neck lies just below the head whereas when the surgical neck continues along down the humerus

where are fractures more common in the humerus?
