Identify the features of a

typical long bone.

1. Diaphysis (bone

shaft)

2. 2 epiphyses (both ends of the bone at the joints)

3. 2 metaphyses(region between diaphysis and epiphysis)

diaphysis)

6. Medullary cavity (hollow space within diaphysis)

7. Endosteum (thin membrane lining the medulary cavity)
