同学们好

我是来自中国农业大学的董玉兰

欢迎同学们学习

动物解剖学这门课程

今天讲述的是消化腺

消化系统的组成

包括消化管和消化腺两部分

其中消化腺

为分泌消化液的腺体

包括壁内腺和壁外腺

壁内腺广泛分布于消化管的管壁内

如胃腺 肠腺

壁外腺位于消化管壁外

形成独立的器官

以腺管通入消化管内

如唾液腺 肝和胰

这节课我们讲述壁外腺

首先学习唾液腺

顾名思义其是分泌唾液的腺体

它分为大小两类

小的唾液腺包括唇腺 颊腺

腭腺和舌腺等

大的唾液腺主要有腮腺

颌下腺和舌下腺

例如牛 羊 马 猪有三对

而犬 兔唾液腺很发达

它有四对

另外还有多眶下腺

猫的唾液腺特别发达

有五对

另外又有多臼齿腺和眶下腺

唾液它具有湿润食料

便于咀嚼 吞咽

清洁口腔和参与消化的作用

牛羊的腮腺

它位于下颌支与寰椎翼之间

呈狭长的倒立三角形

颜色呈一个淡淡的红褐色

上端比较厚

达颞下颌关节部

下端狭小 弯向前下方

位于舌面静脉

与上颌静脉的夹角内

其分泌的唾液经过腮腺管流入口腔

腮腺管起于腮腺下部的深面

随着舌面静脉一起

沿咬肌的腹侧缘

经下颌骨血管切迹

折转到咬肌前缘

开口于颊黏膜的腮腺乳头上

牛羊的下颌腺比腮腺大

呈淡黄色

分叶明显呈新月形

非常发达

从寰椎窝沿下颌角向前下方延伸

至舌骨体

几乎与对侧下颌腺相接

在它的中部

表面被腮腺覆盖

腺的下端膨大

在活体的时候就可以触摸到

它分泌的唾液经过下颌腺管流入口腔

下颌腺管在腺体前缘中部

由一些小管汇合形成向前延伸

横过二腹肌前肌腹的表面

沿舌下腺的下缘

开口于口腔底壁的舌下肉阜上

第三对腺体舌下腺 较小

位于舌体和下颌骨肌之间的黏膜下

它可以分为上下两部分

上部为多口舌下腺

又称短管舌下腺

狭长而薄

从软腭向前深达颏角

以许多小管开口于

舌体两侧的口腔黏膜上

下部为单口舌下腺

又称长管舌下腺 短而厚

位于多口舌下腺前下方

以一条总导管与下颌腺管伴行

共同开口于舌下肉阜上

以上我们学习了牛羊的唾液腺

下面我们比较一下马的唾液腺

马的腮腺位于耳的下方

下颌骨后缘

为不正的四边形

腮腺管起于腺体前缘

经下颌向前延伸

至下颌骨血管切迹处绕至面部

随同面动脉一起

沿咬肌前缘向上延伸

穿过颊肌开口于

第三上臼齿相对处的颊黏膜上

第二个唾液腺 下颌腺

呈月牙形

位于下颌骨内侧

其后部被腮腺覆盖

颌下腺管在下颌支内侧前行

开口于舌下肉阜上

马的舌下腺长而薄

位于舌体和下颌骨之间的黏膜下

舌下腺管有三十多条

均开口于口腔底

舌下黏膜褶上

下面我们再来比较一下

猪的唾液腺

首先看它的腮腺

猪的腮腺很发达

呈三角形

腮腺管开口于

第四 五上臼齿相对的颊黏膜上

猪的颌下腺

呈球形或扁的圆形

颌下腺管开口于

舌系带两侧

口腔底壁的黏膜面上

猪的舌下腺也分为短管和长管两部分

开口于舌体两侧

及舌系带附近

口腔底壁的黏膜面上

下面我们再来比较一下

犬的唾液腺

犬的腮腺比较小

呈不规则的三角形

有时可见小的副腮腺

它的下颌腺较大 淡黄色

上部被腮腺覆盖

犬的舌下腺 淡红色

也分为单口舌下腺和多口舌下腺

好 唾液腺部分我们学习完了
