short bone
cube like in shape
approximately equal in length, width and thickness
carpals and tarsals
provide stability and support as well as some limited motion
flat bones
thin, and curved
protection of internal organs, but also points of attachments for muscles
irregular bone
one that does not have a characterized shape and does not fit into any other classification
tend to have more complex shape
many facial bones and vertebrae
sesamoid bone
small round bone suspended within a tendon or ligament
these bones form within tendons when a great amount of pressure or friction is generated over time
protect tendons by helping them overcome compressive forces
vary in number and placement person to person
patella is the only common sesamoid bone found in every person
articulation
joint where two bone surfaces come together
tend to conform one another ie/ one rounded and one cumed
depression
sunken in portion of the bone where a softer structure, like a blood vessel or organ rests
projection
area of a bone that projects above the surface of the bone
attachment points for tendons and ligaments
size and shape is an indication of the forces that the bone pulls through
hole
opening or groove in the bone that allows some structure like a blood vessel or nerve to pass through the bone
condyle
condyle - rounded surface - ie/ occipital condyles
articulating surfaces
facet
articulating surfaces
facet - flat surface - ie/ vertebrae
head
articulating surfaces
head - prominent rounded surface - head of femur
trochlea
articulating surfaces
trochlea - rounded articulating surface - trochlea of humerus
sulcus
sulcus - groove - sigmoid sulcus of the temporal bones
depressions
fossa
depressions
fossa - elongated basin - ie/ mandibular fossa
crest
crest - ridge - ie/ iliac crest
projections
epicondyle
projections
epicondyle - projection off a condyle - lateral and medial epicondyles of humerus
line
projections
line - slight, elongated ridge - temporal lines of the parietal bones
process
projections
process - prominent feature - transverse process of vertebra
ramus
projections
ramus - long projection (branch) - mandibular ramus
spine
spine - rough round projection for muscle attachment - greater trochanter of femur
projections
tubercle
projections
tubercle - small rounded process - tubercle of humerus
canal
canal - passage in bone - ie/ auditory canal
openings and spaces
fissure
openings and spaces
fissure - slit through bone - articular fissure
foramen
openings and spaces
foramen - opening in bone - foramen magnum in the occipital bone
