Many of the reflex responses have their origin in the spinal cord. The functions of the spinal cord are mainly two:
a) Function driver: Drive motor and sensory information from each side of the spinal cord. Currently the bone is almost completely mapped and know many ways that lead or tracts afferent and efferent myelinated axons through the white matter. Some
pathways are:
1. Spinothalamic pathway, leading to pain and temperature information from peripheral receptors to the brain.
2. Corticospinal tract: Drive motor information from the brain to the spinal nerves.
3. Spinocerebellar tract: Drive information from muscles and tendons to the cerebellar cortex.
4. Goll and Burdach routes: Lead sensitive information related to touch and pressure.
b) Function products: here are made simple behaviors like reflexes. Eg, the patellar reflex, blink reflex and others.
routes processors are:
1. Goll pathways
2. Burdach pathways
3. Lateral corticospinal tract and dorsal spinocerebellar
4. Espinatalamico lateral roads or anterolateral system
5. Spinothalamic tract anterior or ventral spinocerebellar
6. Anterior corticospinal tract.
If an injury occurs at the 5th vertebra cdervical, the paralysis affects the whole body (Cuadraplejia or quadriplegia). If the injury affects only the lumbar region, the paralysis will occur in the lower limbs (paraplegia).
