All of the following are made of dense collagen except:
Correct Answer: Periosteum
Description: Ans. d. Periosteum Periosteum is not formed by dense regular connective tissue. 'Structures formed by dense regular connective tissue are tendons, ligaments and aponeurosis Dense Regular Connective Tissue (DRCT) Provides connection between different tissues in the human body The collagen fibers are bundled in a parallel fashion. In this kind of tissue, elastic and reticular fibers are completely absent. Dense regular tissue can be divided into white fibrous connective tissue and yellow fibrous connective tissue. Both of these types can be arranged in cord or sheet arrangement. Dense Regular Connective Tissue Cord arrangement Bundles of collagen and matrix are distributed in regular alternate patterns Sheet arrangement Collagen bundles and matrix are distributed in irregular patterns, Similar to areolar tissue Dense Regular Connective Tissue Structures formed Tendons: Connect muscle to boneQ Derive their strength from the regular, longitudinal rangement of bundles of collagen fibersQ Ligaments Bind bone to boneQ Similar in structure to tendons. Aponeurosis Functions Has great tensile strengthdeg that resists pulling forces especially well in one direction. Has a very poor blood supplydeg (damaged tendons and ligaments are slow to heal)
