Spine Anatomy

These 3 tips can help you better navigate the process of getting an accurate diagnosis for your disc problem.

The L5-S1 spinal motion segment helps transfer loads from the spine into the pelvis/legs and may be susceptible to degeneration, herniation, and/or nerve pain

Learn the difference between pain that is caused by a disc condition causing nerve root pain (radicular pain) and the disc itself being the source of the pain (axial or referred pain).

The C2-C5 spinal motion segments contribute to the mid-range motion when the neck bends forward and/or backward.

The C5-C6 spinal motion segment provides flexibility and support to the neck. This motion segment may be a source of pain due to degenerative changes, trauma, and poor posture.

The C6-C7 spinal motion segment bears the primary load from the weight of the head and supports the lower part of the neck. This motion segment is susceptible to degeneration, trauma, and intervertebral disc problems.

The C7-T1 spinal motion segment connects the mobile cervical spine with the relatively rigid thoracic spine. This motion segment is susceptible to degeneration, trauma, and intervertebral disc problems.

The L3-L4 spinal motion segment helps to support the weight of the torso and protect the cauda equina.

Due to its load-bearing function, the L4-L5 spinal motion segment may be susceptible to injury and/or degenerative changes.
