The morphology of the soft tissue and supporting cartilage of the vomeronasal organ of the fetal pig was studied from early stages to term. Specimens obtained from an abattoir were aged by crown-to-rump distance. Series of transverse sections show that some time before birth all structures--cartilage, connective tissue, blood vessels, nerves, glands and epithelia--are well developed and very similar in appearance to those of the adult. Furthermore, in transmission electron microscopy photomicrographs obtained at this stage the vomeronasal glands exhibit secretory activity.
对胎猪犁鼻器的软组织和支持软骨的形态从早期到足月进行了研究。从屠宰场获取的标本根据顶臀长度确定年龄。一系列横切面显示,在出生前的某个时候,所有结构——软骨、结缔组织、血管、神经、腺体和上皮——都发育良好,外观与成年猪的非常相似。此外,在这个阶段获得的透射电子显微镜照片中,犁鼻腺表现出分泌活性。
