Fig. 9

Transmission electron micrographs of the anterior region of the silk gland in the caddisworm H. nigrovittatus. Secretory granules (Sg) are electron-lucent spherical granules with fine fibrous materials (asterisks). At the vicinity of secretory granules well developed rough ER (Er), Golgi apparatus (Go), and mitochondria (Mt) are seen. D: Secretory granules are released to the lumen via the microvilli (Mv) by the merocrine secretion. Gradual transition of the secretory materials (asterisks) from cell to lumen are clearly seen. All scale bar indicates 0.5 μm (A)
