Peripheral
The spinal nerves that exit the vertebral column through lateral openings or gaps between the vertebrae are called "intervertebral foramina." These foramina allow the spinal nerves to branch off from the spinal cord and extend to various parts of the body, facilitating communication between the central nervous system and peripheral nervous system. Each pair of spinal nerves corresponds to a specific segment of the vertebral column.
The spine is made up of many vertebrae. These all have cartilage between them to keep your back flexible and to keep the vertebrae apart and allow particular nerves to pass between the vertebrae. osteoarthritis is the wearing out or damage of the cartilage between these vertebrae. This can lead to direct back ache and also interfere with nerves going to the various parts of the body.The cervical spine includes the top 8 vertebrae of the backbone.
nerve plexusesThe spinal nerves emerge from the spinal cord at the brain stem, and between each vertebrae.
The spine needs water to be able to lubricate the joints between the vertebrae. When the spinal column gets low on moisture, the nerves within the canal can get pinched between the vertebrae.
Sometimes inflammation putting pressure on nerves will do this or pressure may be put on the nerves as they pass between the vertebrae in the neck.
The most likely place for pinched nerves is along the vertebrae. the spinal chord has branches that lead of it to the various parts of the body. the bones that make up the vertebrae are made up in such a way as to allow these nerves to pass between the joints. However when the cartilage and other material between the joints wears down or is damaged in some way you end up with a situation where the bone starts to push on it pinching it and interfering wit the messages passing through it.
The brachial plexus are nerves that leave the cervical vertebrae (but originate in the brain) and extend to peripheral structures (muscles/organs) to transmit motor and sensory nerve impulses.
The nerve gets pinched between the vertebrae.
T1-12. These nerves enter from the thoracic or chest vertebrae.
Spinal nerves exit the vertebral column through small openings called intervertebral foramina located between adjacent vertebrae.

If the pain feels like it is on the side of buttocks, it could be a problem with the sciatic nerve. Often, with weight gain and/or old age, the cartilage between the lower vertebrae (lumbar) begins to wear away, and the nerves between these vertebrae pinch the nerves between them, such as the sciatic nerve.
