Q

Adipocytes Fibers

A

All three types (Elastic, Colleagen, and Reticular)

23
Q

Adipocytes Ground Substance

A

colorless, not much

24
Q

Adipocytes Cells

A

Adipocytes (adipose cells) large cells full of fat in living tissue.

25
Q

Adipose Cells

A

large, globular cells in adipose tissue, nucleus pushed to the edge, signet ring appearance

26
Q

Chondrocytes

A

Cartilage Cells

27
Q

Osteocytes

A

Bone Cells

28
Q

Blood Cells

A

Red blood cells, white blood cells, platelets

29
Q

Defense Cells (not in blood) Macrophages

A

eats bacteria and old cells

30
Q

Defense Cells (not in blood) Mast Cells

A

Produce histamine in inflammation

31
Q

Hyaline Cartilage

A

enclosed by perichondrium (vascular), Chondroblasts, Chondrocytes, refractive index of fibers is same as the matrix. You cannot see the collagen

32
Q

Hyaline Cartilage Function

A

Resists compression and a good shock absorber

33
Q

Hyaline Cartilage Location

A

over ends of long bones in many joints, respiratory tract, connections between ribs and sternum

34
Q

Elastic Cartilage

A

Very similar to Hyaline Cartilage except it has lots of elastic fibers in matrix (looks black). Chondrocytes are typically closer together and larger than hyaline.

35
Q

Elastic Cartilage Function

A

resists compression, absorbs shock, maintains shape after twisting/deforming

36
Q

Elastic Cartilage Location

A

ears and nose

37
Q

Fibrocartilage

A

Chondrocytes are typically arrange in rows, separated by coarse collagen fibers, strongest type of fibers

38
Q

Fibrocartilage Function

A

Protection, absorbs shock, found where great pressure is applied to joints

39
Q

Fibrocartilage Location

A

vertebral disks, meniscus of knee

40
Q

Bone (Both Types)

A

osseous connective tissue

41
Q

Bone (Both Types) Fibers

A

Collagen

42
Q

Bone (Both Types) Ground substance

A

Calcified (hard)

43
Q

Bone (Both Types) Cells

A

Osteocytes

44
Q

Bone (Both Types) Functions

A

Support and protection, muscle attachment, and blood cell formation (bone marrow)

45
Q

Long Bone

A

Spongy bone is on the ends, calcified bone is in the shaft

46
Q

Osteon

A

Found in the bone and looks like tree rings

47
Q

Haversian Canal

A

Surrounds nerve and blood vessels

48
Q

Lamellae

A

Surrounds the Haversain Canal

49
Q

Canaliculi

A

Canals between the lacuna of the bone

50
Q

Blood (all 3 types)

A

specialist cells formed inside bones

51
Q

Red blood Cells (erythrocytes)

A

contains hemoglobin which binds to oxygen

52
Q

White Blood Cells (Leukocytes)

A

protects the body from bacteria, viruses and cancer

53
Q

Platelets (Thrombocytes)

A

Shed from very large cells, helps blood clot, very tiny dots in the blood vessels
