The alligator and its allies . X. The tenth nerve, as noted above, is one ofthe two largest nerves of the brachial giving off a single nerve to the ventralmusculature, this nerve unites with the eleventhnerve; it then gives a branch to the costo-coracoid-eus muscle and forms a loop with the ninth giving off a couple of nerves it again dividesinto two equal branches which unite v/ith similarbranches of the eighth nerve. XI. The eleventh nerve is next to the smallestof the plexus. Besides branches to the trunkmusculature it gives a fine twig to the integumentof the axilla and unites with the tenth nerve in thebrachial plexus. This is the last nerve that entersinto the brachial plexus. The distribution of the nerves of the brachialplexus is as follows (Fig. 31): (a) supracoracoideusto the muscle of that name and to the integumentof the breast; (b) thoraci inferiores nerves (loa)—a complex of nerves from the eighth, ninth, andtenth spinal stems—lead to the costo-coracoideus J vn vm a r xi. 22. 22f. 24.
