同学们好

欢迎学习动物解剖学

下面我们学习内分泌组织

内分泌组织是指位于

细胞内的一些内分泌细胞层

第一个是位于胰岛内

胰岛位于胰腺内

是胰腺的内分泌部

细胞排列呈不规则的团索状

分布于腺泡之间

形如岛屿

故称胰岛

胰岛细胞细胞之间

有丰富的有孔毛细血管

有利于激素的透过

第二个内分泌组织是睾丸内的

主要是指的睾丸间质细胞

和支持细胞

睾丸间质细胞分布在睾丸

精曲小管之间的结缔组织中

细胞大而圆

胞质嗜酸性

能分泌雄激素

促进雄性生殖器官发育

及第二性征的出现

同时有促使生精细胞

发育成精子的重要作用

支持细胞位于精曲小管管壁上偏于基膜侧

可分泌少量刺激素

为发育中的精子提供营养和保护

第三个内分泌组织是卵巢内的

卵巢内的内分泌组织主要有门细胞

卵泡膜和黄体

其中

黄体由排卵后的卵泡细胞

和卵泡膜内层细胞演化而成

分泌孕酮和雌激素

孕酮可刺激子宫腺分泌和乳腺的发育

并保证胚胎的附植或着床

并保证胚胎的附植或着床

黄体的发育程度和存在时间

决定于卵子是否受精

若排出的卵受精

黄体继续生长

可维持到妊娠后期

称妊娠黄体或真黄体

若排出的卵没有受精

则黄体只维持2周左右便开始退化

称发情黄体或假黄体

第四

其他内分泌组织或细胞

下丘脑内神经元多数具有内分泌功能

其分泌物一部分在神经垂体内贮存

另一部分通过垂体门脉系统到达腺垂体

对腺垂体的分泌活动进行调节

在消化道粘膜中散在着

种类繁多的内分泌细胞

第三

心房壁内的一些细胞可分泌心房肽

是近十几年来研究极为活跃的

一个神经内分泌激素

具有强大的利尿排钠

扩张血管和降压等生理效应

它在心肌细胞和中枢神经系内均可合成

贮存和释放

同学们

关于内分泌系统的知识就讲到这里
