The reflex can take one of two forms. The biceps, triceps, brachioradialis, and finger flexor reflexes are the most important upper-extremity reflexes. For example, the triceps reflex evaluates C7 to C8, and the brachioradialis reflex evaluate C5 to C6. NEUROLOGY. With an inverted triceps or patellar reflex there is elbow or knee flexion instead of extension. Supinator Reflex. The fibers from each ventral ramus travels along different routes so that each limb muscle receives innervation from more than 1 spinal nerve to have a backup plan in case of injury.
