It Support and bind cells, store water and organic molecules
Ground substance
26
The main adhesion protein that bind collagen fibers and cells to the ground substance
Fibronectin
27
Are very strong, resists pulling (tension), flexible
Collagen fiber
28
It is the most abundant protein in the body (25% of protein in the body)
Collagen fiber
29
It is smaller than collagen, connects fibrous networks within a connective tissue and adds strength and stability
Elastic fiber
30
Retic means?
Net
31
Collagen coated with glycoprotein, provide support forms Stroma (Supporting framework) of many soft organs
Reticular fibers
32
Are Thicker, more densely packed than other types of connective tissues
DENSE CONNECTIVE TISSUE
33
Three types of Dense connective tissues
 Dense Regular Dense Irregular Elastic Connective Tissue
34
A Regularly arranged bundle of fibroblasts in rows
DENSE REGULAR CT
35
Which dense CT is located in the tendons?
DENSE REGULAR CT
36
It Provide strong attachment between various structures, withstand pulling tensions
DENSE REGULAR CT
37
collagen fibers that are irregularly arranged with few fibroblasts
DENSE IRREGULAR CONNECTIVE TISSUE
38
Which dense CT is located in the dermis of skin?
DENSE IRREGULAR CONNECTIVE TISSUE
39
It gives tensile strength
DENSE IRREGULAR CONNECTIVE TISSUE
40
Elastic fiber rich tissue that is yellow when unstained
ELASTIC CONNECTIVE TISSUE
41
Which dense CT is located in the lung?
ELASTIC CONNECTIVE TISSUE
42
It functions for stretching and elasticity
ELASTIC CONNECTIVE TISSUE
43

Group of Chondrocytes
lacunae
47
lacunae means?
Little lakes
48
Dense covering is called?
pericondrium
49
Is glassy, resilient, embedded with chondrocytes found in lacunae surrounded by perichondrium
HYALINE CARTILAGE
50
Which cartilage is the most abundant in the body?
HYALINE CARTILAGE
51
It provide smooth surfaces for movement, flexibility and support, weakest type of cartilage
HYALINE CARTILAGE

It Support and join structure together, strongest type of cartilage
FIBROCARTILAGE
55
Are Chondrocytes in threadlike network of elastic fibers, perichondrium present
ELASTIC CARTILAGE
56
Which cartilage is located in Auricle of ears?
ELASTIC CARTILAGE
