The anterior process of the malleus of the middle ear develops irrespective of Meckel's cartilage through an intramembranous ossification center that appears in the human embryo of 26.5 mm crown-rump length at a caudomedial position in relation to Meckel's cartilage. The malleus has a double origin: the anterior process originates from the os goniale through intramembranous ossification, and the rest from Meckel's cartilage, through endochondral ossification.
中耳锤骨的前突通过一个膜内骨化中心发育而成，与梅克尔软骨无关，该骨化中心出现在头臀长26.5毫米的人类胚胎中，位于相对于梅克尔软骨的尾内侧位置。锤骨有双重起源：前突通过膜内骨化起源于角状骨，其余部分通过软骨内骨化起源于梅克尔软骨。
