蚂蚁和一般的群居昆虫都以其非常发达的外分泌系统为特征。根据细胞排列，许多腺体要么属于上皮型，要么由两个细胞单元组成，每个细胞单元包括一个分泌细胞和一个导管细胞。关于分泌产物的吸收、生物合成和释放的超微结构在这两种类型中是非常相似的，通常涉及质膜表面增加的折叠。角质层构成每个腺细胞的一部分，大部分都有孔道。信息素产生腺的特征是大量的线粒体、发达的高尔基体和广泛的光滑内质网。通常丰富的多层包裹体可能与分泌物质相对应。另一方面，产生有毒物质或执行消化功能的腺体以其发达的颗粒内质网为特征。
Ants, and social insects in general, are characterized by their very well developed exocrine system. According to their cellular arrangement, the numerous glands either belong to the epithelial type, or are composed of bicellular units, each comprising a secretory cell and a duct cell. The ultrastructural organization with regard to the uptake, biosynthesis and discharge of the secretory products is very similar in both types, and generally involves surface increasing foldings of the plasmalemma. The cuticle, that forms part of each glandular cell, is mostly provided with pore canals. Pheromone producing glands are characterized by numerous mitochondria, a well developed Golgi apparatus and an extensive smooth endoplasmic reticulum in their secretory cells. The often abundant multilamellar inclusions may correspond with secretory material. Glands producing venomous substances or performing digestive functions, on the other hand, are characterized by their well developed granular endoplasmic reticulum.
