Adjacent vertebrae articulate through zygapophyseal joints between the respective superior and inferior facets of the vertebral articular processes as well as through the joints of the vertebral bodies. While the former serves to limit the spine's range of motion, the latter increases it and provides the majority of the spine's weight-bearing capacity. The inferior surface of the superior.

Wervellichaam - Corpus vertebrae. 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.

Intervertebral disc anatomy, function, degeneration, herniation
An intervertebral disc is a structure located between adjacent vertebrae of the spine. It consists of a tough outer layer called the annulus fibrosus and a gel-like center called the nucleus pulposus. The intervertebral disc acts as a cushion, allowing the spine to bend and twist without damaging the vertebrae.

Discus intervertebralis 1/3. Synonyms: Intervertebral fibrocartilage, Fibrocartilago intervertebralis The articular surfaces of directly adjacent vertebral bodies are separated by fibrocartilaginous intervertebral discs. They adhere to both the vertebral end-plates and the bony vertebral rim. The attachment to the vertebral bodies is via ring.

Definition/Description. The intervertebral disc (IVD) is important in the normal functioning of the spine. It is a cushion of fibrocartilage and the principal joint between two vertebrae in the spinal column. There are 23 discs in the human spine: 6 in the cervical region (neck), 12 in the thoracic region (middle back), and 5 in the lumbar.

Thoracic vertebrae Anatomy, function and definition Kenhub
Intervertebral discs consist of an outer fibrous ring, the anulus (or annulus) 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.

Introduction. Back pain is a major public health problem in Western industrialized societies. It causes suffering and distress to patients and their families, and affects a large number of people; the point prevalence rates in a number of studies ranged from 12% to 35% [], with around 10% of sufferers becoming chronically disabled.It also places an enormous economic burden on society; its.

The structural elements, both macroscopically and microscopically, together with the biochemical elements, are intimately related to function. The intervertebral disc should not be though of as a homogeneous and static structure; it has a heterogeneous composition and responds dynamically to applied loads. Neither should it be considered as an.

This review article describes anatomy, physiology, pathophysiology and treatment of intervertebral disc. The intervertebral discs lie between the vertebral bodies, linking them together. The components of the disc are nucleus pulposus, annulus fibrosus and cartilagenous end-plates. The blood supply to the disc is only to the cartilagenous end.

Discus intervertebralis. Definition. The intervertebral discs (intervertebral fibrocartilages) are interposed between the adjacent surfaces of the bodies of the vertebræ, from the axis to the sacrum, and form the chief bonds of connection between the vertebræ. They vary in shape, size, and thickness, in different parts of the vertebral column
Spine Basics OrthoInfo AAOS
Intervertebral disc disease is a common condition characterized by the breakdown (degeneration) of one or more of the discs that separate the bones of the spine (vertebrae), causing pain in the back or neck and frequently in the legs and arms. The intervertebral discs provide cushioning between vertebrae and absorb pressure put on the spine.
Intervertebral disc Wikipedia
Discus intervertebralis 1/3. Synonyms: Intervertebral fibrocartilage, Fibrocartilago intervertebralis The anulus is made up of a series of 15-25 concentric rings, or lamellae, with the collagen fibres lying parallel within each lamella. The fibres are oriented at approximately 60 degrees to the vertical axis, alternating to the left and right.
