Bone Matrix

Multinucleated cells that break down the calcified matrix of bone.

• osteoblasts

• osteoclasts

• osteons

• osteocytes

Mixture of calcium salts and collagen fibers that form the rings of compact bone

• lamella

• osteons

• bone matrix

• osteocytes

what are the rings around the haversian canal called?

• lacunae

• lamella

• osteocyte

• volkmann's canal

Dense bone tissue that have a continuous extracellular matrix with no gaps.

• Spongy Bone

• Endosteum

• Compact Bone

• Periosteum

This type of cell dissolves and reshapes bone.

• osteocyte

• osteoclast

• osteoblast

• osteon

OSTEOBLASTS

• bone stem cells able to differentiate into the other types of cells

• bone-building cells that secrete  matrix

• remodel bones and cause them to release calcium

True or False. Bone structure reflects its function.

• True

• False

Central canals contain _________ that nourish the cells of osteons.

• Food sources

• Marrow

• Blood vessels

• Oxygen

Compact Bones

• dense bone in which the bony matrix is solidly filled with organic ground substance and inorganic salts

• consists of plates and bars of bone adjacent to small, irregular cavities that contain red bone marrow

• long cylinders that act as tiny weight-bearing pillars in the bone

• runs through the middle of each osteon and contains small blood vessels for nourishment and nerve fibers for signaling
