2. INTRODUCTION
MAAJIDMALIKOFFICIAL@GMAIL.COM
The normal anatomy of the spine is usually
described by dividing up the spine into three major
sections: the cervical, the thoracic, and the lumbar
spine. (Below the lumbar spine is a bone called the
sacrum, which is part of the pelvis). Each section is
made up of individual bones, called vertebrae.
There are 7 cervical vertebrae, 12 thoracic
vertebrae, and 5 lumbar vertebrae.

An individual vertebra is made up of several parts.
The body of the vertebra is the primary area of
weight bearing and provides a resting place for the
fibrous discs which separate each of the vertebrae.
The lamina covers the spinal canal, which is the
large hole in the center of the vertebra through
which the spinal nerves pass.

The spinous process is the bone you can feel
when running your hands down your back. The
paired transverse processes are oriented 90
degrees to the spinous process and provide
attachment for back muscles.

There are four facet joints associated with
each vertebra.
A pair that face upward and another pair
that face downward.
These interlock with the adjacent vertebrae
and provide stability to the spine.

 The vertebrae are separated by intervertebral discs,
which act as cushions between the bones.
 Each disc is made up of two parts. The hard, tough
outer layer, called the annulus, surrounds a mushy,
moist center, called the nucleus. When a disc herniates
or ruptures, the soft nucleus spurts out through a tear
in the annulus and can compress a nerve root. The
nucleus can squirt out on either side of the disc, or in
some cases, both sides.
