Duvernoy's gland (a type of venom gland) of the Japanese colubrid snake, Rhabdophis tigrinus, was examined by electron microscopy. The secretory units of the gland consist of the secretory and myoepithelial cells. The secretory cells are columnar in shape and have well-developed rough endoplasmic reticulum (RER), Golgi apparatus and mitochondria in the basal perinuclear cytoplasm. The secretory granules are homogeneous in structure and moderately dense. They are accumulated in the apical cytoplasm and are released by exocytosis into the lumen. The myoepithelial cells often enclose the secretory units, contain bundles of filaments in the cytoplasmic process, and are innervated by the free endings of the autonomic nerves through the basement membrane. In addition, many nerve terminals end in pericapillary spaces, suggesting a release of neurosecretions into the blood. The duct epithelium is composed of typical mucus secreting cells, whose cytoplasm contains secretory globules of lower electron density.
对日本游蛇科虎斑颈槽蛇的杜氏腺（一种毒腺）进行了电子显微镜检查。该腺体的分泌单位由分泌细胞和肌上皮细胞组成。分泌细胞呈柱状，在核周基部细胞质中具有发达的粗面内质网（RER）、高尔基体和线粒体。分泌颗粒结构均匀，密度适中。它们聚集在顶端细胞质中，并通过胞吐作用释放到管腔中。肌上皮细胞常围绕分泌单位，在细胞质突起中含有成束的细丝，并通过基底膜接受自主神经的游离末梢支配。此外，许多神经末梢终止于毛细血管周围间隙，提示神经分泌物释放到血液中。导管上皮由典型的黏液分泌细胞组成，其细胞质中含有电子密度较低的分泌小球。
