Diaphysis
Epiphysis
Medullar Cavity
Periosteum
Endosteum
Describe the microscopic structure of compact bone. - ✔✔✔ Correct
Answer > consists of osteons (Haversian systems) with central
canals, lamellae (concentric layers), lacunae (spaces for
osteocytes), and canaliculi (tiny channels connecting lacunae).
What is compact bone? - ✔✔✔ Correct Answer > Dense, organized into
osteons, provides strength.
