Types of Connective Tissue

Ø      Loose connective tissue

§         Areolar tissue

§         Adipose tissue

§         Reticular tissue

Ø      Dense connective tissue

§         Dense regular connective      tissue

§         Dense irregular connective tissue

1) Loose Areolar Tissue

•         Widely distributed, delicate, flexible, well-vascularized, flexible and not very resistant to stress

•         Embedding medium for many structures including blood vessels & nerves, Stroma of most organs

•         Chief examples are s/c tissue, mesentery, omentum

•         All the three basic components of CT are best represented

•         Two most common cell types are fibroblasts & histiocytes

•         Among fibrous components, collagen fibres are most abundant

•         The ground substance is relatively fluid like and occupies many small areas (areolae) in which no structure is seen in H&E stain

2) Adipose Tissue

  • Fat Cells
  • White or unilocular adipose tissue
  • Brown or multilocular adipose tissue
  • ‘Signet ring’
  • More proportion of cells than intercellular substance
  • Found wherever areolar tissue is located

Ø      Functions

•         Temperature regulation

•         Energy reserve

•         Mechanical

3) Reticular Tissue

•         Specialized fibroblasts, reticular cells and reticular fibers

•         Reticular cells are ‘stellate’ shaped with long processes

•         reticular tissue forms a delicate 3-D network.

•         Protoplasmic processes of reticular cells are wrapped around or extend along reticular fibers forming a ‘sponge-like’ appearance

•         Present in liver, spleen, kidney,  bone marrow and lymphoid tissue

Dense connective tissue

•         Closely packed fibers

•         Same components found in loose connective tissue, but there are fewer cells and a clear predominance of collagen fibers and lesser amount of ground substance

•         Less flexible and far more resistant to stress

•         Two types

•         Dense regular connective tissue

•         Dense irregular connective tissue

1) Dense Regular Connective Tissue

•         Dense fibers are arranged parallel to each other in the form of cords or bands

•         Examples: tendons, aponeurosis, ligaments

2) Dense Irregular Connective Tissue

•         Occurs in the from of sheets

•         The component fibers interlace to form dense network

•         Examples: dermis of skin, periosteum, perichondrium, capsules of some organs (liver, testis, lymph nodes)

Elastic Tissue

•         Composed of bundles of thick, parallel elastic fibers

•         Space between these fibers is occupied by thin collagen fibers and flattened fibroblasts

•         Very Elastic

•         Found in the lungs, walls of  arteries, bronchial tubes, ligaments of the vertebral column and in the suspensory ligament of the penis.

  1. Finally something fresh and new that make sense! I would like to see more about this and that is what I’m going to do.

  2. thanx.this is a good site that make concepts clear..
