There was no difference in time to complete healing of all ulcers, with median time to. healing of 328 days with standard care and 365 days with ultrasound. There was no evidence of a difference in rates. of recurrence of healed ulcers (17/31 with ultrasound vs 14/31 with standard care). There was also no difference.
This system is composed of both sensory (afferent) neurons, which carry information from the nerves to the brain and spinal cord, and motor (efferent) neurons, which transmit information from the central nervous system to the muscle fibers.
Once messages leave the central nervous system, they are carried by the peripheral nervous system. The peripheral system includes the cranial nerves (nerves branching from the brain) and the spinal nerves (nerves branching from the spinal cord).These nerves convey sensory messages from receptor cells in the body to the central nervous system.he central nervous system consists of the brain and the spinal cord. The brain lies within the skull and governs body functions by sending and receiving messages through the spinal cord.
