Bone Anatomy Flashcards
Diaphysis
The long central shaft of the bone (green)
Epiphysis
Forms the larger rounded ends of long bones (blue)
Metaphysis
Area between the diaphysis and epiphysis at both ends of the bone (brown)
Physis
Plates of cartilage, also known as growth plates which allow the long bones to grow in length (red)
Apophysis
A normal bony outgrowth that arises from separate ossification center and fuses with the bone in course of time (yellow)
True or False: Closure times are site and species specific
