Sensory (afferent) information is received by spinal nerves distributed throughout the body. The signal passes through the dorsal roots (Figure 2.36) into the spinal cord and then finally up to the brain for processing. Motor commands are initiated in the central nervous system, where a decision by the brain is made to move. The command signal is sent down the spinal cord to the appropriate level, then out the ventral root of the spinal cord (Figure 2.36). The signal is carried via a spinal nerve to its appropriate destination to the muscle fiber to enable a voluntary muscular contraction. Dermatome regions of the skin.
