     subtype:  splanchnic_nerve  any of several nerves of the sympathetic part of the autonomic nervous system that innervate viscera and blood vessels
     subtype:  sciatic_nerve__sciaticnerve__nervus_ischiadicus  arises from the sacral plexus and passes about halfway down the thigh where it divides into the common peroneal and tibial nerves
     subtype:  saphenous_nerve__nervus_saphenus  a branch of the femoral nerve that supplies cutaneous branches to the inner aspect of the leg and foot
     subtype:  ulnar_nerve__ulnarnerve__cubital_nerve__cubitalnerve__nervus_ulnaris  a nerve running along the inner side of the arm and passing near the elbow; supplies intrinsic muscles of the hand and the skin of the medial side of the hand
        subtype:  funny_bone__funnybone__crazy_bone__crazybone  a point on the elbow where the ulnar nerve passes near the surface; a sharp tingling sensation results when the nerve is knocked against the bone; "the funny bone is not humerus"
