Non-Contact Ultrasound Treatment for Wounds. Ultrasound is defined as a mechanical vibration above the upper threshold of human hearing. Ultrasound (US) in the kilohertz range (1â3 MHz) has been used for the treatment of musculoskeletal disorders, primarily by physical therapists. A non-contact low-intensity US device has been developed that does not require use of a coupling gel or other direct contact.
Sensory nerves. Sensory nerves deliver information to your spinal cord from muscles and joints about your body position. They also transmit sensations such as touch, pressure, pain and temperature, which are experienced on the surface of your skin. This information enters your spinal cord via your posterior grey horn.
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.
