Annulus Fibrosus. Annulus fibrosus is a lamellar fibrocartilaginous tissue organized into a series of 15-25 concentric rings or lamellae with a highly oriented, parallel pattern of collagen type I, which are aligned at an angle of approximately 30-42° to the vertical axis and in opposite directions in successive layers (Plate X)
Annulus Fibrosus Regeneration . Regenerating the fibers of the annulus, by means of tissue engineering, is in some ways, according to Bron, et. al., a better solution than suturing. The problem is, it's much more difficult for scientists to pull off

Medical definition of annulus fibrosus: a ring of fibrous tissue (such as that surrounding a heart valve); especially : the outer portion of an intervertebral disk that surrounds the nucleus pulposus and is composed chiefly of layers of collagen fibers Annulus fibrosus or anulus fibrosus may refer to: . Anulus fibrosus cordis — fibrous ring of heart; Anulus fibrosus disci intervertebralis — fibrous ring of intervertebral disk; Anulus fibrosus tympani — annulus surrounding the membrana tympan Annulus fibrosus: Hvor ligger hjertet . Den indre, geléaktige kjernen nucleus pulposus, og ytre annulus fibrosus, som består av mange lag med bindevev. Hva er så de beste (og verste).

Prolaps i ryggen Ryggsøylen består av 24 virvler og mellom hver ryggvirvel ligger det en bruskskive som kalles mellomvirvelskiven. Mellomvirvelskivene har en viktig støtdempende funksjon i ryggraden vår

Mellomvirvelskivene (disci intervertebrales) består av en elastisk kjerne (nucleus pulposus) omgitt av en seig, fibrøs ring (annulus fibrosus) og er forbundet til virvellegemene ved hjelp av endeplatebrusk og bindevev.Konsistensen til kjernen er som en reke uten skall. Mellomvirvelskivene er støtdemperne i ryggsøylen og muliggjør ryggsøylens bøye- og vribevegelser The annulus fibrosus is the tough circular exterior of the intervertebral disc that surrounds the soft inner core, the nucleus pulposus. This outer portion is composed of a ring of ligament fibers that encases the inner core of the disc and securely connects the spinal vertebrae above and below the disc

Intervertebral discs consist of an outer fibrous ring, the anulus fibrosus disci intervertebralis, which surrounds an inner gel-like center, the nucleus pulposus. The anulus fibrosus consists of several layers (laminae) of fibrocartilage made up of both type I and type II collagen.Type I is concentrated toward the edge of the ring, where it provides greater strength anulus fibrosus: [ an´u-lus ] (pl. a´nuli ) ( L. ) a small ring or encircling structure; also spelled annulus . anulus fibro´sus 1. fibrous ring of heart; any of four dense fibrous rings, one of which surrounds each of the major cardiac orifices. 2. fibrous ring of intervertebral disk; the circumferential ringlike portion of an intervertebral. The annulus fibrosus (plural: annuli fibrosi) surrounds the nucleus pulposus and together they form the intervertebral disc.. Gross anatomy. The annulus comprises 15 to 20 collagenous (type I) laminae which run obliquely from the edge of one vertebra down to the edge of the vertebra below. The direction of the fibres alternates from lamina to lamina

How Tears to the Annulus Fibrosus Are Treate

annulus fibrosus The tough fibrous outer zone of the intervertebral disc that normally retains the soft inner nucleus pulposus. Weakness of the annulus fibrosus allows prolapse of the pulpy centre in the condition inaccurately known as 'slipped disc'
Een tussenwervelschijf (lat.: discus intervertebralis) is een ring van vezelig kraakbeen (lat.: anulus fibrosus) met in het midden een geleiachtige kern (lat.: nucleus pulposus) die zich in de wervelkolom bevindt tussen twee afzonderlijke wervels.Ze zijn enigszins elastisch en dragen zo bij aan de schokdemping. Bij een hernia van de rug ligt de oorzaak in een beschadiging van de.

The annulus fibrosus is the thick, protective outer wall of the intervertebral disc structure. This protective wall surrounds the nucleus pulposus on every side and also attaches the disc to the vertebral bones through cartilaginous end plates. The outer disc wall is rarely overly affected by degenerative disc disease, but is the structure which fails in the case of a herniated disc

Olivia M. Torre, Michelle A. Cruz, Andrew C. Hecht, and James C. latridis. Abstract. This chapter describes the clinical need for annulus fibrosus (AF) repair as well as the state of the art in AF repair procedures and next-generation AF repair strategies that aim to improve upon currently available treatments The annulus fibrosus collagen fibrils underwent a change in diameter and elastic modulus from 170 ± 18 to 310 ± 24 nm (P < 0.001) and 0.86 ± 0.12 to 1.27 ± 0.30 GPa (P = 0.003), respectively when measured on the concave side after a loading of 7.2 N MB could generate DNA damage and induce apoptosis in different cell types; however, the effects of MB on intervertebral disc (IVD) annulus fibrosus (AF) cells are not clearly understood. OBJECTIVE: The objective of this study was to investigate the effects of different concentrations of MB on rat AF cells in vitro
