Aortic arches of fishes  -  general pattern of development of arches in cartilaginous fishes :       1 - Ventral aorta extends forward below pharynx & connects developing aortic arches. The first pair of arches develop first.       2 - Segments of first pair are lost & remaining sections become efferent pseudobranchial arteries       3 - Other pairs of arches (2 - 6) give rise to pre- & posttrematic arteries       4 - Arches 2 - 6 become occluded; dorsal segments = efferent branchial arteries & ventral segments = afferent branchial     arteries       5 - Capillary beds develop within nine demibranchs
