25
If a macrophage is present in CT it is called
Histiocytes
26
Has well developed phagocytic ability and specialize in turnover of protein fibers and removal of dead cells and other materials
Macrophage
27
Key component of immune response
Macrophage
28
Antigen presenting cells
Macrophage
29
Differentiated cells
Mature
30
undifferentiated cells
immature
31
Macrophages derived from
bone marrow precursor cells that devide, producing monocytes that circulates in blood. These cells cross epithelial wall of venules to penetrate CT, where they differentiate further, mature and acquire morphologic features of Phagocytic cells.
32
Mast cells granules provide
Matachromasia. which means they can change the color of basic dyes.
33
Mast cells contains
Basophilic secretory granules
34
Basophilic secretory granules serve to
function to loacal inflammatory response, innate immunity and tissue repair.
35
Basophilic secretory granules
``` Heparin Histamine Serene proteases Eosinophil and neutrophil chemotactic factors Cytokines Phospholipids ```
36
Heparin
anticoagulant
37
Histamine
provide increased vascular permeability and smooth muscle contraction
38
Serene proteases
activate various mediators for inflammation
39
Eosinophil and neutrophil chemotactic factors
attracts leukocytes
40
Cytokines
direct activities of leukocytes and other cells of immune system
41
Phospholipids
precursor for conversion of prostaglandins, leukotrienes, and other lipid mediators of the inflammatory response.
42
Sceretes antibodies/immunoglobulin
Plasma Cells
43
B-lymphocytes derived
Plasma Cells
44
Part of humoral immunity-antibodies
Plasma Cells
45
appearance of plasma cells
clockface/cartwheel
46
came from blood/napadaan lang
Transcient cells
47
transcient cells came from blood and migrate to venules to CT by the process called
Diapedesis
48
called by mast cells through chemotactic factor
leukocytes
49
hold our body | tensile strength
collagen fiber
50
stretches | resiliency
elastic fiber
51
very fine/delicate | structural framework
reticular fiber
52
makes up population of wondering cells
leukocytes
53
extremely strong and resilient
collagen fiber
54
most abundant protein in human body
Collagen fiber
55
what type of collagen in reticular fiber
Type III collagen
56
forms reticulum and extremely thin heavily glycocylated fibers
Type III collagen
57
agyrophilic
reticulat fiber
58
thinner than type I collagen
Elastic fiber
59
only seen in blood vessels
Elastic fiber
60
fills spaces between cells and fibers in CT
Ground substance
61
Gags also known as
mucopolysaccharides
62
gags can be
Uronic acis and Hexosamine
63
unoric acid
Glunoric acid and iduronic acid
64
hexosamine
glucosamine and galactosamine
65
composed of core protein which are conveniently attached to various no./combination of gags
proteogylcans
66
milti adhesive glycoprotein
laminin and fibronectin
67
for adhesion
laminin
68
from insoluble fibral netwrok althroughout CT.
fibronectin
69
TYPES OF CT
Loose CT | Dense CT
70
areolar tisse
loose CT
71
regular/irreg
Dense CT
72
common and generally support epithelial tissue
Loose CT
73
flexible/not very resistant to stress
Loose CT
74
more ground substance/cells
Loose CT
75
has more fiber
Dense CT
76
adapted to offer stress resistance and protection
Dense CT
77
has fewer cells
Dense CT
78
bundle of collagen fibers that appear randomly interwoven
Dense irregular CT
79
arranged in a defined pattern with fiber
Dense rregular CT
80
Consist of ground substance with fewer colagen fiber
embreyonic mesenchyme
81
source of multipotent stemcells
embreyonic mesenchyme
82
undifferentiated and have large nuclei with prominent nucleus and fine chromatin
embreyonic mesenchyme
83
embreyonic type of CT
mucoid tissue
84
Found in umbilical chord and fetal organs
mucoid tissue
85
abundant ground substance and composed of hyalunoric acid
mucoid tissue
86
jellylike with sparse collagen fiber and scattered fibroblast
mucoid tissue
87
mucoid tissue is principal component of
wartons jelly
88
reticular tissue is produced by
modified fibroblast called reticular cell
89
reticular tissue seen in
bone marrow, lymph nodes and spleen
