The musculocutaneous nerve is the largest of all the cranial nerves. It controls the arm and shoulder muscles. The main function of these muscles is to act as the major components of our muscular system. Muscles work together in order to allow us to move freely. Muscles control our arm movements, and they also control our arm posture, which is how we use our arms.
The musculocutaneous nerve also innervates the smaller muscles in the front part of our upper arm. These include the infraspinatus, the triceps brachialis, and the brachiocubiciceps. The brachiocubiciceps are long, thin muscles located between the elbow and shoulder blade. The infraspinatus has a broad, flat blade-like bone and a deep tendon insert that connect the muscle to the upper side of our elbow. The radial nerve starts in the neck and runs down our back, passing through our shoulder blades, over our shoulders, and down our arms. The radial nerve passes through the root of our middle finger.
The largest nerve in the body, which is the one that gives us the sensation of arm movement, is the median nerve. It originates in our spinal cord and branches off into the upper, lower, and middle parts of our arms. It is important to note that the musculocutaneous nerve does not run through the entirety of our arm; it only branches off into the area between the elbow and the shoulder blade. This makes the radial nerve much more important when it comes to our ability to bend our arms, because we need the ability to move the arm and not the nerve.
One of our two median nerve branches off of the coracoacoid process starts in our chest cavity near the neck and goes straight to our shoulders. The transversus abdominis is the other branch off of this same nerve, going to our hips. There are actually six sets of these nerves: the superficial (medial), the deeper (transversus inferior), the middle, the superior, and the anterior.
There are several major differences between the anatomy of our musculocutaneous nerve and that of the tendons, ligaments, muscles, etc. In order to properly understand these anatomical variations, it is important to have a basic understanding of our bodies. Muscles are basically composed of bones that are attached through tendons to bones. There are certain types of muscles that are more active during certain movements, while others are less used during certain movements.
One of these is the medial muscles, or the biceps brachei, which are located between the forearms and between the ankle and the knee. These muscles help maintain a balance between the weight of the forearm and the body’s movement. As part of our movement, our biceps also rotate and extend the tendons that control the rotation of our arms. Because of this, when we are extending the arms, we use a combination of our strength along with the power of our biceps. We are able to extend our arms with a good amount of strength, but our ability to extend the muscles without hurting ourselves is lessened due to the constant tension in our biceps. This is why we see people who play sports or other activities that require constant wrist extension, or “throwing the ball,” as being less efficient at maintaining proper motor function while they are moving.
The second part of our movement-the nerves originate in and around the neck. They run through the back of the head and over the scalp to the base of the skull. One of these, the median nerve, branches off into the upper part of our neck, while the cranial nerve, which branches off into the cheek and jaw areas, branches off into the chin and cheeks. Another nerve, the median nerve, also branches off into the upper part of our chest.
The third part of our movement, which involves our arm, is also affected by the musculocutaneous nerve. It begins at the base of our elbow, extends down through the ulnar loop of our wrist, then branches off into the little finger, thumb, index, middle, ring, and small fingers. Because our arm is so large and a long way away from our body, it can be difficult for the nerve to get a grip. It is possible for pain in these areas to be associated with problems elsewhere in our arms (such as arthritis or bursitis), but it’s not likely that this will be the case. Sufferers should seek a doctor’s advice if their arm pain or tingling persists after a few days rest.
Muscles are constantly moving, but they’re not always strong enough to support our bodies. This is why our musculocutaneous nerve system is so important-it carries our nerve impulses through all the major parts of our body. When something isn’t working right, our body has no choice but to “back up” a bit, which it often does with muscles and tendons. When our arm muscles are weak, our nerves aren’t getting the proper signals. If you’re suffering from a pinched nerve, try strengthening your muscles-especially the ones that tend to pin our limbs to the floor when we’re walking. If you do this on a daily basis, you should see improvement in a couple weeks.
