Fig. 2. Electron micrograph of GiUichthvs caudal neurosecretory cell cytoplasm to show elementary neurosecretory
granules (ENG) in region of Golgi lamellae ( GL), which also appear to be producing a lysosomelike body (LB). Note
prominent granular endoplasmic reticulum (ER) and mitochondria (MI). Insert at left shows apparent formation of
granules by Golgi membranes in caudal neurosecretory neuron of Tilnpia mossambicu.
