Nerves
The axillary nerve is located at the proximal end, against the shoulder girdle. Dislocation of the humerus's glenohumeral joint, has the potential to injure the axillary nerve or the axillary artery. Signs and symptoms of this dislocation include a loss of the normal shoulder contour and a palpable depression under the acromion.
The radial nerve follows the humerus closely. At the midshaft of the humerus, the radial nerve travels from the posterior to the anterior aspect of the bone in the spiral groove. A fracture of the humerus in this region can result in radial nerve injury.
The ulnar nerve at the distal end of the humerus near the elbow is sometimes referred to in popular culture as 'the funny bone'. Striking this nerve can cause a tingling sensation ("funny" feeling), and sometimes a significant amount of pain. It lies anteriorly to the medial epicondyle, and is easily damaged in elbow injuries.

Famous quotes containing the word nerves:
““My nerves are bad to-night. Yes, bad. Stay with me.
Speak to me. Why do you never speak. Speak.
What are you thinking of? What thinking? What?
I never know what are thinking. Think.””
—T.S. (Thomas Stearns)
“... this I conceive to be no time to prate of moral influences. Our men’s nerves require their accustomed narcotics and a glass of whiskey is a powerful friend in a sunstroke, and these poor fellows fall senseless on their heavy drills.”
—Clara Barton (1821–1912)
“If we reason, we would be understood; if we imagine, we would that the airy children of our brain were born anew within another’s; if we feel, we would that another’s nerves should vibrate to our own, that the beams of their eyes should kindle at once and mix and melt into our own, that lips of motionless ice should not reply to lips quivering and burning with the heart’s best blood. This is Love.”
—Percy Bysshe Shelley (1792–1822)
