11. With passage of months and years the Aschoff nodules becomes less cellular and collagenous tissue is increased. 12. Pterobranchs are filter-feeders, mostly colonial, living in a collagenous tubular structure called a coenecium. 13. Reticular and collagenous fibers were seen to run along the edges of the VF throughout the entire lamina propria. 14. Connective fibers, often collagenous , are arranged in a helical shape within the wall of the hydrostatic skeleton. 15. Its fibers run in random directions and are mostly collagenous , but elastic and reticular fibers are also present. 16. This work suggested that the optimal osteogenic activity requires a synergy between soluble extract and the insoluble collagenous substratum. 17. The protein may form a trimeric molecule by the association of the collagenous domains of three identical polypeptide chains. 18. This collagenous material can change its mechanical properties in a few seconds or minutes through nervous control rather than by muscular means. 19. In addition to short cytoplasmic and transmembrane domains, there is an extracellular spacer domain and a long, extracellular collagenous domain. 20. By microscopie view, there is an admixture of heavy dense bands of collagenous tissue dissected by fat and abnormal elastic fibers.
