초록
The cerebral neurosecretory cells (NSC) constitute four paired groups, medial (MNC), lateral(LNC-I, LNC-II) and posterior (PNC) in the brain of larvae of tasar silkworm Antheraea mylitta(D) Eco-race Bhandara. The MNC is the largest groups of peptidergic neurosecretory cellsand are located in the pars intercerebralis region. The transmission electron microscopic (TEM),ultrastructure of the NSC confirmed the presence of mitochondria, endoplasmic reticulum,Golgi bodies, lysosomes and neurosecretory granules. The median neurosecretory cellsshows secretory activity and release of secretory products, the neurosecretory granules (NSG)in the axons of NSC as well as the blood sinus.
