Q

Articulating cartilage

A

Protective covering over the articulating ends of long bones.

30
Q

Periosteum

A

Outer covering of bones. Provides attachment for ligaments and tendons and functions in formation and repair of bone.

31
Q

Endosteum

A

Thin membrane containing bone-forming cells. Lines the medullary cavity and the spaces of the spongy bone.

32
Q

Collagen fibers

A

Strong, flexible fibers like those of tendons and ligaments.

33
Q

Osteocytes

A

Bone cell (mature osteoblasts)

34
Q

Lacunae

A

Small pockets where osteocytes are found.

35
Q

Canaliculi

A

“Little canals” Passageways through which cellular processes can pass nutrients and waste from cell to cell.

36
Q

Lamellae

A

Sheets of calcified matrix that surround the osteon. The lacunae are found in between the lamellae.

37
Q

Matrix

A

Fibers and ground substance that surround cells.

38
Q

Ground substance

A

Material that can vary in consistency from liquid to solid. Provided a way to transfer material between the blood supply and cells.

39
Q

Osteon

A

Basic functional unit of compact bone.

40
Q

Central canal

A

Central of the osteon which contains blood vessels and nerves.

41
Q

Perforating canals

A

Canals that run perpendicular to the central canals, they also contain blood and nerves.

42
Q

Spongy bone

A

Has no osteon, the lamellae form rods called trabeculae.

43
Q

Trabeculae

A

Rods that branch frequently forming the extensive open networks of spongy bone.

44
Q

Osteocytes

A

Mature bone cells that under go the normal functions of cells, transferring nutrients and waste to and from nearby cells.

45
Q

Osteoclasts

A

Clasts = break.

Giant multinucleated cells that secrete and acid to dissolve the bony matrix, osteocytes.

46
Q

Osteoblasts

A

Blast= builds

They are responsible for osteogenesis

47
Q

Osteogenesis

A

The formation of the new bone.

48
Q

Ossification

A

The replacement of the other tissues with osseous tissue.

49
Q

IntraMembranous ossification

A

Bone with sheets or membrane, like connective tissue.

50
Q

Ossification center

A

Where ossification begins

51
Q

Endochondral ossification

A

Osseous tissue replaces an existing cartilage model.

52
Q

Primary ossification center

A

Wher the tissue begins to form

53
Q
