21
Q

Sinus

A

Air-filled space in bone

22
Q

Osteocyte

A

maintains bone tissue (mineral concentration)
primary mature bone cell. inside lacuna. secretes enzymes to keep mineral concentration

23
Q

Osteoblast

A

Forms bone matrix (bone formation)

24
Q

Osteogenic cell

A

Stem cell - into osteoblasts

25
Q

Osteoclast

A

Resorbs bone (injury)

26
Q

Diaphysis

A

shaft running between proximal and distal ends of the bone

27
Q

Epiphysis

A

end of each bone, filled with spongy bone

28
Q

medullary cavity

A

hollow region in diaphysis, filled with yellow marrow

29
Q

Compact bone

A

Dense and hard, fills walls of diaphysis

30
Q

Red marrow

A

Fills spongy bone, produces blood cells

31
Q

Epiphyseal plate

A

hyaline layer of cartilage in growing bone; turns to epiphyseal line in adulthood because it is replaced by osseous tisue

32
Q

endosteum

A

membrane lining of medullary cavity, for bone growth and repair

33
Q

long bone

A

cylindrical, greater length than width. arms, legs, fingers, toes. act as levers

34
Q

short bone

A

cube-like, roughly equal l w h. carpals. stability and support

35
Q

flat bone

A

thin and curved. cranium, scapulae, sternum, ribs. point of attachment for muscles, protect internal organs

36
Q

irregular bone

A

all the weird ones. vertebrae, facial bones (sinus)

37
Q

sesamoid bone

A

small and round. in tendons with pressure from joints (knee cap/patella).

38
Q

endosteum

A

membrane in medullary cavity for bone growth and repair

39
Q

diaphysis

A

shaft between proximal and distal ends

40
Q

medullary cavity

A

hollow region in diaphysis

41
Q

compact bone

A

walls of diaphysis, dense and hard

42
Q

epiphysis

A

ends of bone, full of spongy bone and red marrow

43
Q

periosteum

A

surrounds bone, fibrous. blood/lymphatic vessels, nerves here. tendons and ligaments connect t othese

44
Q

joints covered by

A

articular cartilage

45
Q

diploe

A

spongy bone, surrounded by compact bone

46
Q

osteoblast

A

forms new bone, doesn’t divide. secretes collagen and Ca salt.

47
Q

lacuna

A

the little caves in bones

48
Q

canaliculi channels

A

does communication and nutrition movement, in bone matrix

49
Q

osteogenic cell

A

undifferentiated, divides rapidly

50
Q

osteon

A

made of lamellae. one of the little cells seen in microscope

51
Q

central canal

A

runs down osteon, holds vessels and nerves

52
Q

perforating canal

A

lets vessels and nerves out of central canal and into periosteum and endosteum
