1. myofibroblasts
2. fibroblasts
3. Adipocytes
4. Mast Cells
5. White blood cells

Question 3

Answer 3

…

Question 4

How do you differentiate between the different cell types found in connective tissue?

Answer 4

…

Question 5

What are the structural and functional characteristics of connective tissue?

Answer 5

…

Question 6

myofibroblasts

Answer 6

• derived from primitive mesenchyme
• relatively unspecialized
• irregular, star shaped (stellate) or spindle shaped (fusiform) with delicate branching cytoplasmic extensions which form an interlacing network throughout the tissues

Question 7

Fibroblasts

Answer 7

Question 8

fibroblasts

Answer 8

Study the appearance of mature fibroblast found in relatively loose connective tissues

Fibroblasts nuclei are condensed and elongated in the direction of the collagen fibers.

Cytoplasm is greatly reduced in volume

Main function is to maintain the integrity of supporting tissues

There is continuous slow turnover of the extracellular matrix constituents

Question 9

ACTIVE FIBROBLAST IN HEALING WOUND

Answer 9

commonly seen in wound healing

• The nucleus is large and rounded in shape with prominent nucleoli reflecting active protein synthesis
• Cytoplasm is extensive and strongly stained, granular appearance may be evidence of an extensive system of rough endoplasmic reticulum that are involved in protein synthesis

Question 10

Which type of fibroblasts play important role in contraction and shrinkage of the resultant scar in wound healing?

Answer 10

myofibroblasts

Question 11

what are the 3 main forms of connective tissue?

Answer 11

1. connective tissue proper
2. connective tissue with special properties
3. supporting connective tissues

Question 12

connective tissue proper is divided into:

Answer 12

1. loose (areolar)
2. dense regular
3. dense irregular

Question 13

which are the connective tissues with special properties?

Answer 13

1. adipose tissue
2. elastic tissue
3. lymphatic and myeloid tissue
4. mucous tissue

Question 14

supporting connective tissue includes:

Answer 14

1. cartilage

2. bone
