What clinical information can be gained by conducting somatic reflex tests?
When describing the reflex arcs and the neural pathways involved we often limit ourselves to the nerves carrying information from the muscle or tendon to the spinal cord and back. However, it should be clear from our ability to feel the tendon tap as well as the results from the Jendrassik’s maneuver test that it isn’t this simple. What other neural connections must be present ?
Identify the component of the reflex arc that detects changes in the internal or external environment:
Question 6 options:
