Nerve Patterns Arm
Hi this is Dr. John Shim and today I want to talk about some basic nerve patterns. You’ve all heard the term radiculopathy. Radiculopathy is a description of a certain pattern of nerve irritation it can cause weakness numbness pain and also manifest in some changes of your reflexes well. As a orthopedic surgeon and as a doctor I understand nerves have certain patterns associated with it. The best analogy I can use is similar to using a switch at the door. That switch turns on the light in the far end of the office. Well that individual wire that goes from the switch to the far end of the office is similar to a nerve. Nerves that go from your brain also travel down to very specific areas of your body and nerves have certain patterns in the neck. The nerves that were mostly interested in our C5, C6 and C7. The C5 nerve pattern is such that the C5 nerve gives you the ability to use your deltoid. You can bring your arm out to the side. It is also associated with sensation typically to patchy areas along your shoulder and also it’s associated with some reflex findings along your biceps. The biceps reflex. As opposed to the C5 nerve pattern there’s also the C6 nerve pattern. The c6 nerve pattern is associated with use of the hand. Specifically extension of your wrist. There’s also an associated reflex of what’s called a brachial radialis reflex. That’s when the doctor hits your forearm and the hand moves. And it’s also associated with sensation that typically goes to your thumb. There’s also the C7 nerve pattern is associated with strength to your triceps muscle, the ability to straighten out. It’s associated with the reflex along the triceps where you hit the end of the elbow and the arm moves and it’s also associated with sensation. The C7 nerve pattern is the middle finger. So as you can see each individual nerves typically follow a pattern in a nerve in the neck and are associated with specific muscle groups, specific areas sensation and for some associated with certain reflexes. This is Dr. Shim talking about nerve patterns. I hope you got some information that was useful to your studies.
