Spinal Column: Nerves
The spinal cord is the main pathway for information connecting the brain and the rest of the body. The human spinal cord is protected by the bony spinal column, which is made up of small bones called vertebrae.
There are 31 vertebrae: eight cervical, 12 thoracic, five lumbar, five sacral and one coccygeal.
There are nerves that extend out from each section of the spinal cord. Messages are passed from skin receptors to the spinal cord by these nerves.
Spinal Nerves/Spinal Cord
Spinal nerves are really important because they send special signals with motor, sensory and autonomic information from the body to the spinal cord allowing them to communicate. Motor is movement. Sensory is vision, hearing, touch, taste and smell. Autonomic is the involuntary actions like heart beat and breathing. These things are essential to life but we don’t have to think about each breath we take because it happens automatically.
