同学们好

欢迎大家学习动物解剖学

下面我们学习内分泌系统中

甲状腺这个器官

甲状腺一般位于喉后方

第2-5个气管软骨环的两侧和腹侧面

由左右两个腺叶

和中间的腺峡组成

呈棕红色或红褐色

甲状腺外覆有纤维囊

称甲状腺被囊此囊伸入腺组织

将腺体分成大小不等的小叶

甲状腺被囊的表面

覆盖胸骨甲状肌

和胸骨舌骨肌

不同动物

甲状腺的形态会略有差异

例如牛的甲状腺

它呈黄褐色

由左右侧腺叶和腺峡组成

腺叶发达

呈扁三角形

腺小叶明显

腺峡较发达

由腺组织构成

绵羊甲状腺呈红褐色

左右腺叶长椭圆形

腺峡不发达

山羊甲状腺的左右两侧叶不对称

腺峡也较小

马甲状腺呈红褐色

左右的腺叶卵圆形

腺峡不发达

较细且由结缔组织组成

连接腺叶的后端

猪的甲状腺呈棕红色

位于胸前口气管的腹侧面

腺峡特别发达

与左右腺叶连成一个整体

在有的个体

其腺峡有向前突出的锥状叶

犬的甲状腺位于气管前部

在第6第7气管环的两侧

腺体呈红褐色

包括两个腺叶和两叶之间的腺峡

腺叶呈卵圆形或扁平椭圆形

腺峡性状不定

甲状腺是富有弹性

质地较为致密的腺体

表明包有富含弹性纤维的结缔组织被膜

被膜深入到腺体实质

将腺体分成许多腺小叶

腺小叶由许多大小不一的滤泡组成

其周围有丰富的毛细血管和淋巴管

甲状腺分泌甲状腺素
