Functions of the bone
provides the supportive framework for the body
allows for attachment for muscles
Types of bones based on shapes
long bones short bones flat bones irregular bones sesamoid bones
Long bones
femur, humerus
Short bones
wrist, ankle
length and width equal
Flat bones
ribs, skull
plate like broad surface
Irregular bones
vertebrae
variety of shapes
Sesamoid bones
patella
small, rounded within tendons
