Excerpt from EMS Care EMT Chapter 24-MCIT-F3-2132 | Head and Spine Injuries

The spinal cord runs through the vertebral canal, protected by bone, membranes, and fluid. Thirty-one pairs of spinal nerves exit between vertebrae to serve specific body regions. These create a predictable pattern of sensation and motor function called dermatomes. Understanding this pattern helps us identify the level of potential injuries during our assessment.

Video: The American Spinal Injury Association classifies spinal cord injuries according to spinal cord level and completeness of injury. A complete or Level A spinal cord injury results in no sensory or motor function in the S4 to 5 spinal cord segments. Each spinal nerve provides sensory innervation to areas of the skin called dermatomes. A C4 to 5 Level A spinal cord injury results in partial or total loss of sensation in the C4 and C5 dermatomes and total sensory loss below. Motor loss from a C4 to 5 Level A injury results in tetraplegia or quadriplegia, which is characterized by partial or total loss of arm movement and total motor loss below. Structures with no motor function may include the diaphragm, requiring ventilator respiratory assistance.
