摘要
研究三角鲂(Megalobramaterminalis)脑垂体的超微结构.脑垂体由神经垂体和腺垂体构成.神经垂体组织中存在A1、A2和B型神经分泌纤维和一种脑垂体细胞.腺垂体由促肾上腺皮质激素分泌细胞(ACTH)、催乳激素分泌细胞(PRL)、生长激素分泌细胞(GH)、促甲状腺激素分泌细胞(TSH)、促性腺激素分泌细胞(GTH)、促黑色素分泌细胞(MSH)、PAS-反应细胞和一种非分泌类型的星状细胞(SC)构成.并讨论三角鲂神经垂体和腺垂体的结构特点.
The ultrastructure of the pituitary was examined in Megalobrama terminalis. The pituitary gland consists of neurohypophysis and adcnophyphophysis. Three types of neurosecretory fibres (A1,A2 and B) and one pituicyte have been recognized in neurohypophysis. The adcnophyphophysis is mainly composed of Adrenocorticotrophic cells, Prolactin cells, Growth hormone cells, Thyrotrophs cells, Gonadotrophic hormone cells, Melanophore-stimulating hormone cells, Periodic acid-Schiff-positive cells and one non-secretory cell type-stellate cells. The ultrastructural characteristics of neurohypophysis and adcnophyphophysis in Megalobrama terminalis are also discussed.
