  • Title: Coil-like structure of the inner core of chordae tendineae.
    Author: Sato I.
    Journal: Clin Anat; 2002 May; 15(3):196-8. PubMed ID: 11948954.
    Abstract:
    Scanning electron microscopy was used to examine the chordae tendineae in young (approximately 20 years old) and old (approximately 85 years old) cadavers. A network of collagen fibrils was observed in both the outer and intersurface layers of the chordae tendineae. In young subjects, a regularly arranged series of disconnected collagenous ring-like structures surrounded the longitudinal collagen bundles forming the inner core of the chordae tendineae. In old subjects, the ring-like structures of the chordae tendineae were few or absent. The ring-like structures may be related to reducing mechanical stress during the tightening, twisting, and slackening of the chordae tendineae.
