The term "sexual dimorphism" refers to any differences in form, whether those differences be morphological, chemical, or physiological in nature. Sexual dimorphism may be manifested as differences in size, morphological appearance, metabolic activities, responses to hormones, drug sensitivity, rates of maturation, etc. The first report, in 1940, of a sexual dimorphism of salivary glands was that of morphological differences between the submandibular glands (SMG) of male and female mice. The sexual dimorphism of the mouse SMG is probably the most widely studied sexual dimorphism of salivary glands. The sexual dimorphism of the mouse SMG has been examined using nearly all methods of study--from neuroanatomical studies of the adrenergic stimulation of secretion by these glands to electrophoretic analysis yielding zymograms of enzymes present in mouse SMG extracts. In addition to a brief review of the sexual dimorphism of the mouse SMG, this report will examine some less well-known examples of salivary gland sexual dimorphism.
“性二态性”一词指的是在形态上的任何差异，无论这些差异本质上是形态学、化学还是生理学上的。性二态性可能表现为大小、形态外观、代谢活动、对激素的反应、药物敏感性、成熟速率等方面的差异。1940年关于唾液腺性二态性的首次报告是关于雄性和雌性小鼠下颌下腺（SMG）之间的形态学差异。小鼠SMG的性二态性可能是唾液腺中研究最广泛的性二态性。人们几乎使用了所有研究方法来研究小鼠SMG的性二态性——从对这些腺体肾上腺素能刺激分泌的神经解剖学研究到对小鼠SMG提取物中存在的酶进行电泳分析以产生酶谱图。除了对小鼠SMG的性二态性进行简要综述外，本报告还将研究一些不太为人所知的唾液腺性二态性实例。
