Question

Name three types of dense connective tissue and their features

Answer 1

Answer

Three types of dense connective tissue are :

• Dense regular connective tissue
• Dense irregular connective tissue
• Elastic connective tissue

Features :

1) Dense regular connective tissue

• It is made up of collagen fibers that are arranged parallel to each other.
• The primary type of cells present in fibroblast.
• This tissue contains very little amount of elastin fibers.
• Example : Tendons and Ligaments

2) Dense irregular connective tissue

• It is also primarily made up of collagen fibers and contains fibroblast cells.
• But, the arrangement of collgen fibers is irregular.
• This tissue functions to resist tension.
• Dermis (second layer of the skin) is made up of dense irregular connective tissue.

3) Elastic connective tissue

• This tissue contains less amount of fibroblast cells and collagen fibers.
• The fibroblast cells secrete elastin fibers.
• The elastic fibers provides the ability to stretch and recoil its original shape.
• Example : Tissue in lungs (helps in inhalation and exhalation)
