On the sensitive innervation of the ostrich's foot pads.

The sensitive and autonomic innervation of foot pads in the ostrich was studied employing an usual histological technique as hematoxylin-eosin or different gold chloride impregnations. The autonomic innervation is represented by isolated or grouped ganglion cells located along the course of nerve bundles. The sensitive somatic innervation is composed by free and capsulated nerve endings usually distributed in the thickness of the connective arrangement of the foot pads, in the most superficial part the first one, while the latter was generally located close to the blood vessels.
