Figs. 772 and 773.—Distribution of cutaneous nerves. Fig. 773.—Posterior aspect. The Anterior Divisions of the Second, Third, Fourth, Fifth, and Sixth Thoracic Nerves and the Small Branch from the First Thoracic Nerve (nn. intercostales) are confined to the parietes of the thorax, and are named thoracic intercostal nerves. They pass forward in the intercostal spaces below the intercostal vessels. At the back of the thorax they lie between the pleura and the posterior intercostal membrane, piercing the latter, and course between the two planes of Intercostal muscles as far as the middle of the rib. They then enter the substance of the Internal intercostal muscles, and, running amidst their fibres as far as the costal cartilages, they gain the inner surface of the muscles, and lie between them and the Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Gray, Henry, 1825-1861; Spitzka, Edward Anthony, 1876-1922.
