Lateral, Posterior, Anterior
what are the 3 funiculi the white matter of the spinal cord are organized into
Bundle of axon fibers that carries sensory information from lower extremities back to spinal cord
Nerves that transmit information from upper extremities back to spinal cord.
Anterior White Commisure
