Final answer:
Connective tissue proper includes both loose and dense connective tissues, with the latter being further divided into dense regular and dense irregular types. Dense regular connective tissue has parallel collagen fibers, while dense irregular connective tissue features a meshwork of interwoven collagen fibers for multidirectional strength.
Step-by-step explanation:
Connective tissue proper is known as either loose connective tissue or dense connective tissue. Dense connective tissue is further classified into two types: dense regular connective tissue and dense irregular connective tissue. Dense regular connective tissue contains collagen fibers that are packed into parallel bundles, providing strength and resistance to stretching along the fiber orientations, commonly found in ligaments and tendons. Meanwhile, dense irregular connective tissue is characterized by collagen fibers interwoven into a mesh-like network, allowing for strength in multiple directions, which is crucial in areas such as organ capsules and artery walls.
