Figure 7. A, dorsal view of m. biventer cervicis (m. biv. c., dark outline) and m. longus colli dorsalis pars cranialis of Aquila chrysaetos. Note the tendon intervening between anterior and posterior bellies of m. biv. c. M. complexus has been removed. B, dorsal view of m. transversospinalis capitis (m. trans. cap., dark outline) of Alligator mississippiensis. Medial and lateral portions of m. trans. cap. in Alligator are not distinguished here. C, lateral view of m. trans. cap. of Alligator mississippiensis (dark outline). D, m. complexus (dark outline) and m. rectus capitis lateralis (light outline) of Pelicanus occidentalis in lateral view. E, m. complexus of Pelicanus occidentalis, outlined in dark grey on the right. This is a dorsal view, with anterior towards the top. F, dorsal view of dissected Alligator mississippiensis, with m. epistrpheo-capitis lateralis, m. spinocapitis posticus and m. transversospinalis cervicis outlined in grey. M. transversospinalis capitis has been removed. G, m. splenius capitis of Anas platyrhynchos, from C2 to the occiput, outlined in grey, in posterior view. M. complexus and m. biventer cervicis have been removed. H, m. epistropheo-capitis medialis/m. altoïdius capitis of Caiman crocodylus, outlined in grey. M. transversospinalis capitis and m. epistropheo-capitis lateralis have been removed.
