#5
What is the basic structural unit of compact bone, consisting of concentric layers of calcified matrix?
Osteon
ExplanationThe Osteon is the basic unit of compact bone, composed of concentric layers surrounding a central canal.
#6
Which structure connects osteocytes in compact bone?
Canaliculi
ExplanationCanaliculi are small channels connecting osteocytes in compact bone, facilitating communication and nutrient exchange.
