What is the function of interstitial lamellae in bone tissue?

They are responsible for bone formation directly from connective tissue.

They represent remnants of old Haversian systems partially obliterated by newly formed osteons. (correct)

They are formed on the inner surface of the bone by osteoblasts derived from the endosteum.

They are laid down by osteoblasts from the periosteum on the outer side of the bone.

Which type of ossification involves the formation of bone directly from connective tissue?

Intramembranous ossification (correct)

Periosteal ossification

Endochondral ossification

Interstitial ossification

What is the primary role of osteoclasts in bone remodeling?

Initiate intramembranous ossification

Form circumferential lamellae
