Connective tissue overview

Question 1

structure of the overall tissue

Answer 1

1.large intercellular spaces
2. loosely packed tissue
3.a significant part consists of only matrix

Question 2

connective tissue cell structure

Answer 2

1.living
2.loosely spaced
3.low in number

Question 3

Matrix of connective tissue

Answer 3

1.can be fluid, gel-like or hard and solid
2.non-living
3.fills the gaps between the loosely packed connective tissue cells
4.fibrous in nature
5.the nature of the matrix decides the function of the connective tissue

Question 4

Matrix origin
extra information

Answer 4

1.it is secreted by the component cells. they contain a chemical, GAGs, called glycosaminoglycans or mucopolysaccharides

Question 5

material inside the matrix

Answer 5

as it is fibrous;
1.White collagen fibers—strength
2.Yellow elastic fibers or elastin—–flexibility
3.Reticular fibers by reticulin

Question 6

functions

Answer 6

1.binding of other body organs or tissues together
2.creates a packaging around organs to prevent displacement while movement of the body
3.connecting and anchors body organs

Question 7

Cells of connective tissue

Answer 7

1.FIBROBLASTS—-form ground substance and fibers like collagen
2.MACROPHAGES—-free-moving or fixed phagocytes/WBCs/leucocytes. remove damaged cells from tissues
3.ADIPOSE CELLS—-store fats and lipids in the form of fat globules in their vacuoles
4.MAST CELLS—-secrete substances like, heparin, serotonin and histamine. promote inflammation of infected area
5.IMMUNOCYTES—leucocytes, produce antibodies, improve immune response

Question 8

Types of connective tissues

Answer 8

1.Dense Regular:
*tendons
*ligaments
2.Areolar
3.Adipose
4.Skeletal:
*bone
*cartilage
5.Fluid:
*blood
*lymph
