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
