Fig. 9.

Three-dimensional reconstructions (a and b) of an adult Arom+ mouse penis with accompaning tissue sections whose position is indicated on the 3DR by the tip of the white arrows. Similar to Fig. 8m–o, this specimen also has an abnormal MUMP, but in this case the MUMP is represented as three distal processes devoid of cartilaginous cores. The 3DRs have been artificially enlarged so as to stretch their dimensions to facilitate viewing. Surface skin is denoted by the tan color. The three distal MUMP-like projections are denoted in red, yellow and turquoise. A shorter epithelial-surfaced process is denoted in green. In (a) part of the skin has been rendered semitransparent to visualize the urethra in purple. Magnifications of the sections are variable and indicated by scale bars.
