Bone & Bone Tissue: Physiology II

These flashcards cover key vocabulary related to bone and bone tissue physiology, their structures, types, and growth processes.

Collagen fibers

Protein fibers that provide structural support and strength to bone tissue.

Osteocytes

Mature bone cells that maintain bone tissue.

Osteoblasts

Bone-forming cells that synthesize new bone matrix.

Osteoclasts

Bone-resorbing cells that break down bone tissue.

Woven Bone

Bone tissue with collagen fibers randomly oriented, formed during embryonic development.

Lamellar Bone

Organized bone tissue structured into sheets called lamellae.

Spongy Bone

Bone with a porous structure, found inside irregular bones and flat bones.

Compact Bone

Dense bone tissue that forms the outer layer of bones, providing structural support.

Trabeculae

The supporting structures in spongy bone that are rod-like or plate-like.

Osteon

The functional unit of compact bone, consisting of central canals surrounded by lamellae.

Periosteum

Connective tissue that covers the outer surface of bones.

Endosteum

Membrane that lines the inner surfaces of bones, including the medullary cavity.

Epiphyseal Plate

A cartilaginous area that allows for bone growth in length during development.

Intramembranous Ossification

Bone development process that occurs directly within connective tissue membranes.

Endochondral Ossification

Bone formation process where cartilage is replaced by bone.

Appositional Growth

Bone growth that occurs by adding new bone on the surface of existing bone.

Bone Remodeling

The ongoing replacement of old bone tissue by new bone tissue.
