The penile bone and anterior process were made anorganic for scanning electron microscopy. The mature bone has a basal bulb and a long, cylindrical shaft bevelled at its tip to fit under a matching surface on the anterior process, giving rise to a bevelled 'suture'. A rough, resting, Sharpey-fibre bone surface covers the base and tip of the bone, the dorsal crest along the shaft, and parts of the lateral and ventral surfaces. The penile bone grows by endochondrial ossification at its basal end, but the cartilage cells are randomly disposed and not arranged in columns as in most 'long' bones. The growing bone, at 8 weeks, shows evidence of resorption externally where the base 'waists in' to the shaft: the corresponding endosteal surface within the basal bulb is formative, in accordance with the 'V-principle' of remodelling. It is concluded that the anterior process, penile bone and proximal erectile body (corpus cavernosum) form a firm, tightly fastened, articulating chain, perhaps serving to aid penetration.
将阴茎骨和前突进行脱钙处理以用于扫描电子显微镜观察。成熟的阴茎骨有一个基部球茎和一个长的圆柱形杆体，杆体尖端呈斜面，以适配前突上匹配的表面，从而形成一个斜面“缝合处”。粗糙的、静止的、含沙比纤维的骨表面覆盖着阴茎骨的基部和尖端、沿杆体的背嵴以及部分侧面和腹面。阴茎骨通过其基部的软骨内成骨生长，但软骨细胞是随机分布的，不像大多数“长”骨那样排列成柱状。在8周时，生长中的阴茎骨在基部向杆体“变细”的外部区域显示出吸收的迹象：根据重塑的“V原则”，基部球茎内相应的骨内膜表面是形成性的。得出的结论是，前突、阴茎骨和近端勃起体（海绵体）形成了一个牢固、紧密相连的关节链，可能有助于性交插入。
