BONE SHAPES:
SUTURAL BONES: [Wormian bones]
Flat, irregularly shaped bones between the flat bones of the skull.
There are individual variations in the number, shape and position of
the sutural bones.
,IRREGULAR BONES:
Have complex shapes.
SHORT BONES:
Boxy
With approximately equal dimensions.
FLAT BONES:
Have thin, parallel surfaces.
Which produce a flattened shape.
LONG BONES:
Relatively long and slender.
Consisting of a shaft with two ends that are wider than the shaft.
SESAMOID BONES:
Usually small, round and flat.
Shaped somewhat like sesame seed.
They tend to develop with tendons.
May form in at least twenty-six locations.
BONE MARKINGS:
Characteristics of a bone’s surface that have specific functions, such as
joint formation, muscle attachment or the passage of nerves and blood
vessels.
Mature bone cells are called osteocytes, bone
building cells are called osteoblasts.
Osteoclasts are bone resorbing cells.
Detailed examination of bone markings in can yield anatomical
information. Ex. Anthropologists, criminologists and pathologists can
determine the size, shape, age, sex, and general appearance.
Bone markings provide fixed landmarks that can help to determine
the position of the soft tissue components of other organ systems.
