TYPES OF BONE Divided in to four classes: 1) long bone:dyaphysis(body,shaft),epiphysis 2)Short bone 3)Flate bone 4)Irreglar bone
Surfaces of bone EMINENCES AND DEPRESSION TWO KINDS: 1)Articular eminences and depression 2)Non-articular eminences and depression
ARTICULAR EMINENCES ARTICULAR DEPRESSION NON-ARTICULAR EMINENCES: Tuberosity,protuberance,process…..tubercle…spine…. crest,ridge,line NON-ARTICULAR DEPRESSION:fossa,pit,depression,groves Fissures,notches,furrows
Processes formed for articulation
.head ,neck .condyl .trochlea .facet
OPENINGS .FORAMEN .CANAL. .SINUS AND ANTRUM
