A

supportive framework

22
Q

what fibers is reticular tissue made of?

A

reticular fibers

23
Q

where is reticular tissue found in the body?

A

BONE MARROW, liver, kidney, spleen, lymph nodes

24
Q

what are the three different type of blood cells?

A

red, white blood cells, and platelets

25
Q

bone/cartilage - what is osteogenic?

A

beginning of the bone, bone stem cells

26
Q

bone/cartilage - what is osteoblast?

A

builds and repairs the bones

27
Q

bone/cartilage - what is osteoclast?

A

breaks down bones

28
Q

bone/cartilage - what is an osteocyte?

A

bone cells

29
Q

bone/cartilage - what is osteon?

A

the functional unit of the bone

30
Q

structures inside the osteon - what is haversion?

A

the central canal that houses blood vessels and nerves

31
Q

structures inside the osteon - what is lacunae?

A

small spaces that contain osteocytes (bone cells), 1 osteocyte for every lacunae

32
Q

structures inside the osteon - what is canaliculi?

A

small canal, runs through bones solid matrix

33
Q

what is spongy bone?

A

looks like a spongy structure, less compact, and formed by trabeculae

34
Q

what type of tissue is found in bone marrow in the spongy bone?

A

reticular tissue

35
Q

where is spongy bone found in the body?

A

where bones aren’t heavily stressed (long/flat bones)

36
Q

what is the structure of cartilage?

A

spaced out, lots of matrix (cellular fluid)

37
Q

what does cartilage hold/contain?

A

has lacunae, holds chondrocytes (cartilage cells)

38
Q

what does cartilage rely on?

A

diffusion for nutrients to get rid of cellular waste

39
Q

what are the 3 types of cartilage?

A

hyaline, elastic, fibrocartilage

40
Q

what is hyaline cartilage?

A

most common type of cartilage in the body, it is strong but flexible

41
Q

where can you find hyaline?

A

around bones, specifically the tip of your nose below the bridge

42
Q

what kind of fiber is in hyaline cartilage?

A

elastic fibers

43
Q

what is elastic cartilage?

A

cartilage that is not clumped in a specific way and is able to expand and be flexible

44
Q

what is the function of elastic cartilage?

A

provides support and tolerates distortion

45
Q

where is elastic cartilage found?

A

the outside of the ear (moves easily), auricle of external care

46
Q

what is fibrocartilage?

A

cartilage that resists compression

47
Q

what fibers are found in fibrocartilage?

A

collagen fibers

48
Q

what is the function of fibrocartilage?

A

it is durable/doesn’t move much, resists compression

49
Q

where is fibrocartilage found in the body?

A

vertebrae/meniscus, pads within the knee joint
