Long bones
greater in length than width
Flat bone
Thin
SHort bones
cube shaped
Irregular bones
complex shaped
Articulating surfaces bone markings
condyle, facet, head, trochlea
Condyle
Large, smooth, rounded, oval structure (end of femur)
facet
Small, flat, shallow surface
head
Prominent, rounded epiphysis (little bone at the tip of pelvis)
Trochlea
Smooth, grooved, pulleylike process (Bottom of humorous)
Depression
Alveolus, fossa, sulcus
Alveolus
deep pit or socket in the maxillae or mandible
Fossa
flattened (indent at the bottom of the humerus
Sulcus
narrow groove ( top of humorous)
Projections
Crest, epicondyle, line, process, ramus, spine, trochanter, tubercle, tubersity
Crest
Narrow, prominent, ridge-like 9(EDGE OF PELVIS)
Epicondyle
projection adjacent to a condyle
line
low ridge (the inside of the hole in pelvis)
Process
any marked bony prominence (cheek bone)
Ramus
angular extension of a bone relative to the rest of the structure (top of jaw)
Spine
Pointed slender process (bottom of edge of pelvis)
Trochanter
massive, rough projection found only on femur ( the top)
