Intervertebral Disc Anatomy

The cartilaginous layers of the end plates anchor the discs in place. Without intervertebral discs the spine would simply be a rigid column of bone but with the addition of discs the spine is a marvel of strength and flexibility.

Section 1 Chapter 1 Anatomy Of The Lumbar Intervertebral

The disc serves a dual purpose one as part of a joint complex that allows for the various movements of the spine including bending flexion and torsion.

Intervertebral disc anatomy. During these changes nociceptive nuclear material tracks and leaks through the outer rim of the annulus. The discs allow some vertebral motion. The intervertebral discs are the largest structures in the body without a vascular supply.

The embryology of the intervertebral disc begins during the fourth week. As the disc ages degeneration occurs osmotic pressure is lost in the nucleus dehydration occurs and the disc loses its height. There are a total of 24 disks in the human spine.

They also serve to protect the nerves that run down the middle of the spine and intervertebral disks. The intervertebral disc forms the fibrocartilaginous joint which allows slight movement. Anatomy of the lumbar intervertebral discs introduction.

This is the main source of discogenic pain. Development of the intervertebral disc begins in the 5th week. The intervertebral disc is a.

Between each vertebral body is a cushion called an intervertebral disc. Each disc absorbs the stress and shock the body incurs during movement and prevents the vertebrae from grinding against one another. The ivd also plays a vital role in the proper absorption and distribution of stress during compressive load bearing.

Understanding intervertebral disc anatomy is the first step in defeating herniated disc pain. The normal human spinal column contains 23 fibrocartilage intervertebral discs. A disc is a soft tissue which helps to cushion the vertebral bones inside the spine.

Section 1 chapter 1. The intervertebral discs are fibrocartilaginous cushions serving as the spines shock absorbing system which protect the vertebrae brain and other structures ie. The intervertebral disc ivd is an integral component of the vertebral column.

An intervertebral disk acts as shock absorber between each of the vertebrae in the spinal column by keeping the vertebrae separated when there is impact from activity. The anulus is made up of a series of 15 25 concentric rings or lamellae.
