19
Q

What three types of cells can a fibroblast become?

A

adipocyte, chondrocyte, osteoblast

20

21
Q

What are the two functions of fibroblasts?

Which is the main function?

A

Structural and Defensive

Structural

22
Q

What is a mature fibroblast?

23
Q

What is the function of fibrocytes?

What can it not do that a fibroblast can do?

A

make ground substance

24
Which type of cell appears flat? a. fibroblast b. fibrocyte c. myofibroblast d. adipocyte Which doesn,t divide? Which is responsible for wound healing and tooth eruption?
b. c
25
Adipocytes are usually derived from what type of cell?
mesenchyme cells
26
plasma cells are derive from what?
B lymphocytes
27
What cells produce antibodies?
plasma cells
28
What cells contain residual bodies?
macrophages
29
T/F | Macrophages can divide.
True
30
T/F | Macrophages are derived from mesenchyme cells
F | derived from monocytes
31
Where do macrophages typically come from?
bone marrow
32
What are some examples of macrophages?
Kupffer cells, alveolar macrophages, monocytes, microgliaLangerhans cells, osteoclasts
33
What kind of granules do mast cells contain?
cytoplasmic
34
Do mast cells divide?
yes
35
Mast cells are derived from what? What where they originally thought to be derived from?
bone marrow basophils
36
Mast cells mediate what events?
A. Inflammation B. Immediate Hypersensitivity Response C. Anaphylaxis D. Asthma – most types
37
What are the four primary mediators that mast cells release?
Histamine, Heparin, ECF, NCF
38
T/F | Heparin increases blood flow to affected area by vasodilating arteriole and small vessels
false Histamine is the on switch
39
Histamine causes the contraction of any __________ __________ muscle
smooth visceral
40
What does ECF do?
attracts eosinophil
41
What are the effects of eosinophil?
- Inhibit leukotrienes - Produce a factor that inhibits mast cell degranulation - Phagocytize IgE-allergin complexes and mast cell granules - Secretes histaminase
42
Eosinophils limit the effect of what two primary mediators?
histamine and leukotrienes
43
Leukotrienes amply the effect of what?
histmine
