R29: Other symptoms and signs involving the nervous and musculoskeletal systems

R29.2: Abnormal reflex

Nerves carry information from the body to the spinal cord. This information is triggered by stimuli such as touch or light. This information is then analyzed in the spinal cord. The result of this analysis is fed back to the body through other nerves, where there is an appropriate response. This response can be a movement of a muscle, for example. This whole process is independent of the will. This is called a reflex.

Some of your reflexes may, for example, be stronger or weaker than normal. Certain reflexes may not exist at all. There can be a variety of reasons for this.
