It resembles the ulna in Pygochelidon [cyanoleuca] and Notiochelidon [murina] rather than in any species of Tachycineta, Petrochelidon, or Hirundo by this combination of characters: olecranon stouter in lateral aspect; cotyla dorsalis with greater overhang of corpus ulnae; and tuberculum carpale more tapered (less squared) in dorsal or ventral aspects.
Heart rate was measured by counting heart sounds with a stethoscope placed 5 cm behind the left olecranon.
In this process two inclinometers were involved: one of them was set on the spine of the scapula and the other one placed on the posterior face of the humerus, touching the olecranon.
For ulnar nerve stimulation, electrodes were placed over the groove between the olecranon of the ulna and the medial epicondyle of the humerus on the back of the elbow (where the ulnar nerve is most superficial).
He had surgery six days later to repair a stress fracture of the olecranon, a bone behind the elbow.
