Five Primary Functions of the Skeleton System
Found between the flat bones of the skull (Form close to suture)
Small irregular bones
Have complex Shapes Example: spinal vertebrae, pelvic bones (don’t fit a generalized shape)
Irregular Bones
Small and thick Example: ankle and wrist bones (short and boxy found in cluster)
Short Bones
Thin with parallel surfaces
Found in the skull, sternum, ribs, scapulae (Bigger bone between the suture)
Flat Bones
Long and thin
Found in arm legs, hands, feet, fingers and toes
Long bones
Small and Flat
Develop inside tendons near joints of knees, hands and feet
Sesamoid Bones
Depressions (fossa) or grooves
Bone markings
Where blood and nerves enter bone
tunnels (canal, channels)
(bone cells) within lacunae organized around blood vessels
Osteocytes
Form pathways for blood vessels
Exchange nutrients and wastes
Canaliculi
Two thirds of bone matrix is
calcium phosphate, Ca3(PO4)2
