Which connective tissue category includes loose and dense connective tissues, arranged in irregular or regular conformations?

• A. Dense Connective Tissue
• B. Loose Connective Tissue
• C. Specialized Connective Tissue
• D. Connective Tissue Proper

Answer: (D)

Connective Tissue Proper is the broad category that includes the ordinary connective tissues you encounter in most parts of the body. It encompasses loose connective tissue, which has more ground substance and fewer fibers (providing cushioning and support), and dense connective tissue, which has a higher collagen content and less ground substance (giving strong, rope-like or leather-like strength). In dense connective tissue the collagen fibers can be arranged in regular patterns, as in tendons and ligaments that pull in a single direction, or in irregular patterns, as in the dermis that resists forces from multiple directions. This combination of loose and dense tissues, with their different fiber organizations, sits within Connective Tissue Proper, while specialized connective tissues (cartilage, bone, blood, etc.) belong to a different category.
