Imagine a railroad station with trains chugging in and out in every direction. What is the benefit of a nice railroad station that runs smoothly? All trains run on schedule and all the passengers are happy.
Your spinal cord is just like a railroad station. Instead of trains, however, nerves enter and exit the “station” at various points: the process is called innervation. They slide into the spinal cord by passing in between vertebrae. From the spinal cord, they travel to and from the body’s muscles, organs and other structures.
Each vertebra has its own set of nerves that weave in, out and around it. Dysfunction or injury of the vertebrae can short-circuit this intricate wiring system. Ongoing research indicates that vertebral subluxations may affect nerve transmission and the structures those nerves innervate.

The Anatomy Of Spine That Gets Range Of Motion And Flexibility.
with its numerous components, is also known as the vertebral column or backbone.
Dr. Masoud Shamaeizadeh of Soft Touch Chiropractic in Porter Ranch California spends countless hours navigating this strong but flexible superhighway full of twists, turns and exits. Even the slightest deviation on this intricate highway can spur complications ranging from carpal tunnel syndrome to headaches, backaches, infantile colic and ear infections.
The spine is actually a chain of 24 bones known as vertebrae, which rest
on a bone called the sacrum — below which is the coccyx. In between the
vertebrae are joints. These joints are cushioned by fluid-filled “pillows”
called inter vertebral discs (IVDs).The soft inner section of the IVD is
called the nucleus pulposa. Surrounding the nucleus is the sturdier annulus
fibrosis.The vertebral column extends from the skull to the pelvis. In addition to keeping us vertical, its most important job is protecting the spinal cord.
Types of Vertebrae
Vertebrae are categorized by position,shape and function: Cervical — Taking it from the top down, the first seven vertebrae are known as cervical (C1-C7). These
lightweight bones allow for maximum range of motion and flexibility.
Thoracic — The 12 vertebrae in this category form the central part of the
spinal column. Located in the upper back, each of the thoracic vertebrae is
attached to a rib.Lumbar — Located in the small of the back, the five stocky lumbar vertebrae are the ultimate workhorses: bearing the weight of the head and the trunk.
Sacrum — This triangular area includes five fused bones and is flanked
by the pelvic bones (illium). Coccyx — Also known as the tailbone, it consists of four fused vertebrae.
Dr. Masoud Shamaeizadeh of Soft Touch Chiropractic in Porter Ranch California explains that, although excessive side-to-side spinal curves (scoliosis) are dysfunctional,slight front-to-back curves are essential to spinal health.
The spine’s unique design gives it strength and flexibility. Shock absorption is also enhanced — as is balance:the latter by keeping the trunk of the body placed squarely over the feet. The three normal curves of the vertebral column are:
Cervical lordosis (neck) — the apex in the front or anterior of the body.
Loss of this curve results in a straightened or “military” neck. Reversal of
this curve results in a jetting forward of the head, or “forward” neck.
Thoracic kyphosis (upper back) —the apex in the back or posterior. Ex-
cessive kyphosis results in “hunch back.”
Lumbar lordosis (low back) — the apex in the anterior of the body.
Strong abdominal muscles prevent excessive lordosis or “sway back.”
Vertebrae View Typically, vertebrae consist of a weight-bearing outer bone, called the centrum, which is attached to a ring shaped arch. Working together, they protect a hole known as the vertebral foramen — where the spinal cord passes through. Ligaments and back muscles stabilize the vertebral column and create a series of checks and balances.
Vertebral Subluxations It’s easy to imagine how the delicate
balance of the vertebral column can be upset. Repetitive motion, trauma,
sports activities and office work may all generate slight alterations in spinal
alignment. When vertebrae become misaligned or spinal movement is restricted, the result is a condition known as vertebral subluxation. This
common occurrence is linked with a myriad of health concerns, such as
carpal tunnel syndrome, headaches,backaches, infantile colic and ear infections.
Chiropractors correct vertebral subluxations with safe and gentle maneuvers called chiropractic adjustments.
But how do they detect this condition in the first place?
Doctors of chiropractic use the sense of touch — known as palpation — to
determine the existence of vertebral subluxations. In addition, range-of-
motion restriction, postural imbalances and muscle tension often indicate the presence of vertebral subluxations. Orthopedic and neurological tests further assist chiropractors inidentifying the condition.
