their arborizations could be divided into three different regions based on both their morphological features and their position within the retinal layers : ( 1 ) an internal arborization , spreading at the margin between the inner nuclear layer and the inner plexiform layer , composed of long , thick , somatofugal dendrites branching at acute angles , ( 2 ) an external arborization in the middle of the inner nuclear layer , formed by short , thin , varicose , recurved , axon-like processes branching at right angles , ( 3 ) and one or more scleral process ( es ) , originating either from the cell body or from the internal arborization , running toward the outermost cell row of the inl , some of which reached the outer plexiform layer .
