-人类锤骨柄与鼓膜之间的关系已被研究，主要关注鼓膜的纤维层及其与锤骨的附着方法。这种连接在脐的水平上是最亲密的，并且随着短过程的接近而逐渐变得更加脆弱。锤骨的长突由一个骨核组成，在其整个长度周围有一个明确的软骨套。这个软骨被之前称为骨膜的软骨膜层所包围。在其下三分之一处，纤维固有层似乎均匀分裂，然后纤维不知不觉地与柄周围的软骨膜层混合。在高水平处，连接不那么紧密，大多数纤维似乎通过锤骨柄外侧。鼓膜-锤骨连接处的胚胎学发育已被考虑，该区域的解剖特征已被考虑与功能要求有关。
— The relationship between the malleus handle and the tympanic membrane in humans has been studied with primary attention being directed to the fibrous layer of the tympanic membrane and its method of attachment to the malleus. This attachment is most intimate at the level of the umbo and becomes progressively more tenuous as the short process is approached. The long process of the malleus, comprised of a bony core, has a definite sleeve of cartilage surrounding its entire length. This cartilage is surrounded by a perichondrial layer which has previously been termed a periosteum. In the lower third, the fibrous lamina propria appears to split equally and the fibers then blend imperceptively with those of the perichondrial layer surrounding the manubrium. At high levels, the attachment is less intimate, most of the fibers appearing to pass lateral to the malleus handle. The embryologic development of the tympanic membrane-malleus junction has been considered and the anatomical features of this area have been considered in relation to functional requirements.
