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.
Sensory neurons receive impulses and carry them from the sense organs to the spinal cord or brain. Interneurons connect sensory and motor neurons and interpret the impulse. Motor neurons carry impulses from the brain and spinal cord to muscles or glands.1  Draw and label the structure of a typical nerve cell.) motor neurons âcarry impulses from the brain and spinal cord to muscles or glands. The Response Mechanism. When a stimulus is received by a sensory neuron, the impulse (or message) is carried through fibrous extensions called dendrites to the cell body.
