There are two main systems that makeup our body, the Central Nervous System (CNS) and the Peripheral Nervous System(PNS). The CNS is composed of the brain and spine. The PNS puts the brain intouch with the physical environment, and allows it respond accordingly.

The Peripheralnerves snake from our spinal cord of the rest of our body. The spinal cordplays a huge factor in communicating the information from the brain to the restof the body.It is part of the Axial Bones, this is essentially thefoundation of your skeletal structure and what keeps your together. Your spineis made up of 24 bones called vertebrae.

Between each bone is a disc that isknown as the intervertebral disc. The bones are further connected by smallmuscles called multifidi that allow you to move your spine in conjunction withthe larger muscles of your body.The spine is divided into five regions; the Cervical,Thoracic, Lumbar, Sacral, and Coccygeal, the tailbone. Each region has spinalnerves coming out the area which helps in transferring information to the restof the body. The Cervical spine is the neck region; this includes eight spinalnerves. It protects the brain stem, support the skull, and allow head movements. Thesenerves branch to the head, neck, shoulders, arms, and hands. Next is the Thoracicvertebrae, which is the under the cervical spine and this contains twelvespinal nerves.

This is attached to the rib cage and ligaments, helps protectvital organs and keeps them in place. These spinal nerves connect portions ofthe upper abdomen and muscles in the back and chest areas.The Lumbar spine is the third region of the spine, thisvertebra is the largest and carry most of the body’s weight. It allows morerange of motion than the thoracic spine. It enables flexion and extensionmovement but actually limit our ability to rotate.

The spinal nerves snake tothe lower back and legs.The Sacrum located behind the pelvis, it fits the two hipbone connecting the spine to the pelvis, forming a triangular shape. The spinalnerves in this region supply to the legs, feet, genital areas of thebody. Lastly is the Coccyx, which isalso known as the tail bone, this only has one spinal nerve attaching to it. Thereis a lot going in our spinal column where millions of axons and neurotransmitterstravel up and down the spine transporting information to our brain.

Thisinformation makes our body move into different positions. There are four waysour spine can move, flexion, hyperextension, lateral flexion and rotation. Eachregion of the spine specializes in each position.

For example, the Thoraxregion has moderate flexion, slight hyperextension, moderate lateral flexionand rotation. But the Lumbar region which can do all these movements can onlyrotate slightly. In conclusion, the purposeof your spine is to provide stability and keep you in an upright position whichimproves your posture, enable flexibility allowing movement, protects yourspinal cord and spinal nerves, and lastly it supports your head by keeping itin firm position.
