Three stranded collagen molecules are packed together to form collagen fibrils and their alignment yield characteristic ultrastructural striations. Dense regular connective tissue is composed of three main components: fiber producing cells, fibers, and an extracellular fluid matrix. This creates a tissue that has tensile strength in all directions. flashcard set{{course.flashcardSetCoun > 1 ? “I would honestly say that Kenhub cut my study time in half.” {{courseNav.course.mDynamicIntFields.lessonCount}} lessons Specialized connective tissue comes in surprising forms. Last reviewed: October 29, 2020 Collagen fibers have good tensile strength and are therefore important in support. It can be found in a number of locations within the body, including the dermis of the skin, in glandular tissue, in the walls of organs, and in the whites of the eyes. List at least five types of connective tissues and two locations for each listed type. Dense regular tissue is found in tendons, ligaments, and muscle fascia. It's actually these fibers that give this connective tissue its name; collagen fibers are densely packed and arranged in a parallel, undulating, regular pattern - hence, dense regular connective tissue. Dense connective tissue is dense because of the high proportion of fibers that run parallel to each other. It has less ground substance than loose connective tissue. All rights reserved. Dense regular connective tissue provides connection between different tissues. The 3-dimensional nature of dense irregular connective tissue gives it a great deal of strength.
