Keeping your spine healthy and strong is important to feeling and being your best self. From understanding the anatomy of your spine to knowing different conditions that can affect it, it’s essential to stay informed about this essential part of your body. Here are 14 important facts about the spine that everyone should know.

1. Anatomy of the Spine

Spinal Curvatures

The spine is comprised of 33 individual bones known as vertebrae that are stacked on top of each other in an “S” shaped curve. This curve is referred to as the spinal curvature and it’s divided into four main sections: the cervical, thoracic, lumbar and sacral. The cervical region consists of seven vertebrae and is located at the top of the spine. The thoracic region includes 12 vertebrae and is located directly below the cervical region. The lumbar region consists of five vertebrae and the sacral region consists of five fused bones.

Intervertebral Discs

In between each vertebra are small, shock-absorbing discs that are comprised of cartilage and connective tissues. These intervertebral discs cushion the spine during movement and provide stability.

Facet Joints

The two adjacent vertebrae are connected by small synovial joints which are known as facet joints. These facet joints are responsible for supporting and maintaining the spine’s structural integrity, as well as controlling movement of the spine.

2. Function of the Spine


The spine is essential for movement of the body as it is designed to support the body’s weight and to provide flexibility. Its structure allows us to bend, twist, turn and walk.

Protection of Organs

The spine also plays an important role in protecting the organs located in the torso. It encases the spinal cord which acts as a hub of communication between the brain and the rest of the body.


Having the correct posture is important for keeping the spine healthy and strong. It is essential for proper balance and alignment and can help to prevent back pain, tension and fatigue.

3. Types of Spine Conditions

Degenerative Disc Disease

Degenerative Disc Disease (DDD) is a condition that is characterized by the breakdown and degradation of the intervertebral discs in the spine. Common symptoms of this condition include back pain, stiffness and limited range of motion.


Spinal fractures can occur as a result of a traumatic event or due to weakened bones which are the result of a degenerative condition such as osteoporosis or cancer. Symptoms of a spinal fracture include back pain, loss of sensation or movement, and weakness or numbness in the arms or legs.

Spinal Stenosis

Spinal stenosis is a condition in which the bone, ligaments or disc widen, narrowing the spinal canal that encases the nerve roots. This can cause pain, numbness, weakness or difficulty in motor function.
