Hi,
Apparently, the C5 and C6 reflex arc are tested when examining the biceps reflex. Does this also mean that the muscle itself is innervated by C5 and C6?
The thing here is that I get confused when source A states that, for example, brachioradialis is innervated by radial nerve (C5-C7) and source B states that the reflex arc for this muscle include C5, C6 and not C7. Why is the reflex arc not testing C7?
