The human spine is a complex structure that provides both mobilities (so to bend and twist) and stability (so to remain upright). The normal curvature of the spine has an “s”- like curve when looked at from the side. This curvature allows even distribution of weight and withstands stress.
The spine is made up of 33 bones called vertebra. The spine is divided into 3 parts:
♦ Cervical spine (neck region) – has 7 bones – C1 to C7
♦ Dorsal or thoracic spine (upper back region) – has 12 bones – T1 to T12 or D1 to D12
♦ Lumbar spine (low back region) – has 5 bones – L1 to L
Finally below the lumbar spine, there is Sacrum and Coccyx (formed by 5 fused bones each).
Between each bone (vertebra) lies a flat, circular disc (intervertebral disc). The outer part of the disc is tough and strong called annulus. The inner portion is soft and absorbs shock called nucleus pulposus.
The spine surrounds and protects the spinal cord (very similar to how skull bone protects our brain). Peripheral nerves come out from the spinal cord. Nerves that come out from the cervical region (neck) go to the arms and hand, nerves from dorsal or thoracic spine go around chest and abdomen and nerves from lumbar spine go to the legs and genitalia.
Thus it is so easy to understand that if somebody has low back pain with pain going down along the nerve distribution to the leg i.e has Lumbar pain with sciatica then this is most likely due to slip disc (Lumbar prolapsed disc or PIVD). Similarly, neck pain with arm pain is likely due to a slipped disc in the cervical region. Slip disc problems are 100% easily treatable – call +91 9920483232
