The neck supports and assists in movement of the head. It is the most flexible part of the spine and consists of 7 cervical vertebrae, cervical segment of the spinal cord, spinal nerves, ligaments, tendons and muscles. Neck pain can be secondary to a problem affecting any of these structures.
Back pain or backache is the pain felt in the back that may originate from muscles, nerves, bones, joints or other structures in the spine. Back pain is one of the most common medical problems experienced by most people at some time in their life. Back pain can be acute, usually lasting from a few days to a few weeks or chronic, lasting for more than three months.
The spine is made up of a column of small bones called vertebrae that surround and protect the spinal cord and nerves that branch out from the spinal cord. Each bone or vertebra is separated from the other by a spongy tissue called an intervertebral disc, which acts as a cushion and prevents the bones from rubbing against each other during movement.
Sciatic nerve is the largest and longest nerve in the body. It originates in the lower back, runs along the hip and back of the leg and finally terminates in the foot. Sciatica is characterized by severe pain in the leg resulting from compression or damage to this nerve.
Spinal stenosis is the compression of spinal nerves caused by narrowing of spinal canal and it is one of the common causes of low back pain. The symptoms include back pain, burning or aching type of pain in buttocks that radiates to the legs (sciatica), weakness in the legs or "foot drop”.
Scoliosis is a condition where the spine or back bone is curved sideways instead of appearing in a straight line. It can occur in all ages, but commonly occurs in children before puberty, during their growth spurt.
Spinal Cord Injury
The spinal cord is a bundle of nerves that extends from the base of your brain down to your lower back. These nerves are responsible for the conduction of signals from your brain to the rest of your body to help in its various functions. It is protected by a bony canal formed by vertebrae arranged one above the other as any injury to these nerves can disrupt normal functions.
