Question

Parts A,B,C and D of the areolar connective tissue are shown in the diagram. Selection the option which gives correct identification along with its functions/ characteristics

• A. A-Macrophage,secrete maximum amount of matrix / ground substance ,help in phagocytosis.
• B. B-collagen fibres most abundant protein in biosphere.
• C. C-mast cells ,their granules contain chemicals like histamine,heparin and serotonin.
• D. D-Fibroblast principal cells of this tissue and secret maximum amount of matrix

Answer 1

Answer: (C)

C-mast cells ,their granules contain chemicals like histamine,heparin and serotonin.

Areolar connective tissue is a loosely arranged connective tissue that is widely distributed in the Body and contains collagen fibres, reticular fibres and a few elastic fibres embedded in a thin, almost fluid-like ground substance.

A- Fibroblast - responsible for synthesizing (creating) the collagen, elastin, and reticular fibres of the tissue.

B- Collagen fibres- thickest of the fibres within areolar tissue. Collagen fibres provide the tissue with a high degree of stretch while protecting the tissue from tearing.

C- Mast cells - responsible for synthesizing histamines, which act as an immune response to allergens and result in tissue inflammation.

D- Macrophage - these cells phagocytize (eat up) pathogens or germs or infectious cells found in the body

So the answer is 'C-mast cells, their granules contain chemicals like histamine, heparin and serotonin'.
