【摘要】 利用组织切片和超薄切片对性成熟雌黄颡鱼的脑垂体进行了组织学和超微结构的研究.黄颡鱼的脑垂体由垂体神经部和垂体腺部组成,垂体腺部又由前叶、间叶和后叶三部分构成.含有嗜酸性和嗜碱性细胞,促肾上腺皮质激素细胞和催乳激素细胞组成腺垂体前叶,促性腺激素分泌细胞、促生长激素分泌细胞、促甲状腺激素分泌细胞组成腺垂体间叶,腺垂体后叶由促黑色素激素细胞构成.更多还原

【Abstract】 The histology and ultrasstructure of pituity gland from sexually matured female pelteobagrus fulvidraco were studied. The pituitary gland consisted of neurohypophysis and adenohypophysis. The adenohypophysis was divided into anterior lobe,intermediate lobe and posterior lobe. There are two types of cells:the acidophile and the basophile. Prolactin cell(PROL) and adrenocorticotopic hormone cell (ACTH) form the anterior lobe,the gonadotropic hormone cell(GTH),growth hormone cell(GH) and thyrotropic hormone cell(TSH) form the intermediate lobe,the posterior lobe consists of melanotropic stimulating hormone cell (MSH).更多还原
