同学们好
欢迎大家学习动物解剖学
这节课讲的是内分泌系统中的
松果体器官
松果体为是一个豆状小体
它的颜色在反刍动物呈红褐色
在马猪犬呈灰白色
位于间脑背侧中央
丘脑和四叠体之间
由于位于第3脑室顶
故又称为脑上腺
一端借细柄与第3脑室顶相连
第3脑室凸向柄内形成松果体隐窝
松果体分泌褪黑激素的
主要作用是抑制性腺
和副性器官器官的发育
防止性早熟
这在调节马
绵羊等动物的季节性生殖周期方面
起着重要作用
春天随着白天时间的延长
褪黑激素生成减少
对性腺的抑制功能减弱
马的性腺活动增加
有利于繁育
秋天随着光照时间缩短
褪黑激素合成增加
而绵羊褪黑激素具有促性腺的功能
褪黑激素分泌增加有利于性腺活动
所以绵羊繁育季节在秋季
这具有很重要的临床意义
因为可以利用褪黑激素
来促进绵羊的繁育周期
