Draw and Label a CHILD’S LONG BONE; include a brief statement about each item.


Here are the 5 Regions and 10 Structures you must specifically address in the sketch, with your
labels, and in your brief narrative:


I.   5 Regions:       1)   Proximal Epiphysis
                      2)   Proximal Metaphysis*
                      3)   Diaphysis
                      4)   Distal Metaphysis*
                      5)   Distal Epiphysis

(* Note: These regions will assume different forms depending on the age and stage of
         development of the individual.)




II. 10 Structures:    1) Articular cartilage (and what tissue subtype/type it is composed of)
                      2) Spongy bone (and what structural unit goes with this type of osseous c.t.)
                                        (Also, what substance is contained within it)
                      3) Compact bone (and what structural unit goes with this type of osseous c.t.)
                      4) Epiphyseal plate (in a child’s bone)
                      5) Medullary cavity (and what substance is contained within it)
                      6) Specific type of bone marrow
                      7) Periosteum – including the TWO layers of which it is composed
                      8) Endosteum – including the TWO layers of which it is composed
                      9) Nutrient foramen
