Dense Regular Connective Tissue

   Dense connective tissue is characterized by an abundance of fibres with fewer cells, as compared to the loose connective tissue.  It is also called fibrous or collagenous connective tissue because of the abundance of collagen (collagenous) fibres. Little intercellular substance is present. Furthermore, in this tissue type, the fibres are organized in a regular, parallel pattern.. Hence, the name – dense regular  connective tissue
