Dense connective tissues

Dense connective tissue

It contains tightly packed collagen fibres, making it stronger than loose connective tissue, and it is of two types : dense irregular tissue and dense regular tissue. You can find Connective Tissue Examples below.

Dense irregular tissue has fibroblasts and many fibres (mostly collagen) that are oriented differently. This type of connective tissue produces tough coverings that package organs, such as capsules of kidneys and adrenal glands. It also covers muscle as epimysium, nerves as perineurium and bones as periosteum. The above image represents a Chart of Connective Tissue Types.

• Dense regular tissue has collagen fibres present in rows between many parallel bundles of fibres. It is of two types as discussed in the table below:

Types connective tissue:

White fibrous tissue

Structure: It consists of mainly white (collagen) fibres which are arranged in bundles. The fibroblasts are present in rows between the bundles.

Types – Sheets & Cords

Sheets: The sheets formed by this tissue occur in the dermis of the skin, connective tissue sheaths of muscles and nerves and tunica adventitia of large blood vessel, periosteum, perichondrium, pericardium, duramater and renal capsule, etc.

Cords: The white fibrous connective tissue forms cords called tendons, which connect the skeletal muscles with the bones.

Function: It has great strength, however its flexibility is limited. The presence of white fibrous tissue at the joints between skull bones makes them immovable.

Yellow elastic tissue

Structure: This tissue is mainly made up of much thicker branched loose network of yellow elastic fibres. The fibroblasts are irregularly scattered.

Sheets: The sheets formed by this tissue occur in the walls of blood vessels, lungs, bronchioles, true vocal cords, cartilage of larynx and trachea.

Cords: The yellow elastic connective tissue forms cords called ligaments which join bones to bones.

Function connective tissue: This tissue has considerable strength and remarkable elasticity. Thus, it allows stretching of various organs. Any anomaly in the synthesis in this tissue may lead to Connective Tissue Disorders.
