30
Q

Sesamoid bone

A

located in the tendons

31
Q

Ectopic bone

A

pathological bone formation

32
Q

Epiphysis

A

two ends of a long bone which are wider than the shaft and take part in the formation of a joint

33
Q

Diaphysis

A

shaft of a long bone

34
Q

Compact bone

A

bone laid down in layers making it appear solid, forms the outer surface of all bones, thicker in the diaphysis and thinner in the epiphysis

35
Q

Spongy bone

A

composed of very thin, plates of bone that meet, other, bones at various, angles, leaving spaces between them. located in the epiphysis

36
Q

Periosteum

A

connective tissue composed of 2 layers.

37
Q

Periosteum outer layer

A

tough fibrous layer that serves as a place of insertion for muscle tendons

38
Q

Periosteum inner layer

A

delicate cellular layer responsible for promoting growth and diameter of the bone

39
Q

Endostem

A

is a thin, cellular layer found lining the medullary cavity and the cavities of spongy
bone. Primary function is to destroy the bone allowing for growth in diameter of the marrow cavity

40
Q

medullary cavity

A

A cavity running the length of the diaphysis that contains either red marrow (which actively forms
blood cells), yellow marrow (where fat cells are stored), or a combination of the two.

41
Q

Articular cartilage

A

Thin layer of hyaline cartilage covering the articular surface of each epiphysis. This cushions the joints

42
Q

Articular capsule

A

connects the bone and encircles the join. Has two layers an outer layer and inner.

43
Q

Epiphyseal disc

A

allows for growth in the long bone, it is not present once growth is complete

44
Q

Metaphysis

A

spongy bone tissue

45
Q

hyaline cartilage

A

embryo, epiphyseal discs, articular cartilages, costal cartilges, larynx, trachea, and bronchi, and nasal cartilages

46
Q

Fibrocartilage

A

interpubic disc and intervertebral discs

47
Q

Elastic cartilage

A

Auricle (ear), auditory tube and epiglottic
