how we become aware of sensory information that is transmitted via a peripheral nerve
1 all the motor axons pass into the ventral roots before uniting with the sensory axons to form the mixed nerves. 2  It connects a large part of the peripheral nervous system to the brain. 3  Information (nerve impulses) reaching the spinal cord through sensory neurons are transmitted up into the brain. Information (nerve impulses) reaching the spinal cord through sensory neurons are transmitted up into the brain. 2  Signals arising in the motor areas of the brain travel back down the cord and leave in the motor neurons.
