Editing Penis (section)

=== Tunica albuginea ===

*Tough connective tissue layer composed primarily of type I collagen
* '''A bilayered structure (inner circular, outer longitudinal)''' with multiple sublayers.
** '''<span style="color:#ff0000">Outer longitudinal layer</span>'''
***'''<span style="color:#ff0000">Completely absent on the ventral groove between the 5 and 7 o'clock positions.</span>'''
****'''The most vulnerable area in the tunica albuginea'''
*****'''Most prostheses tend to extrude here''' 
****'''<span style="color:#ff0000">The lack of tunica albuginea on the ventral groove may contribute to greater ease of dorsal buckling and explain why most PD patients exhibit dorsal curvature</span>'''
*****'''<span style="color:#ff0000">60-70% of plaques are located on the dorsal aspect of the penis</span> and are usually associated with the septum'''
*'''Covers the corpora cavernosa and *spongiosum'''
**'''*The corpus spongiosum lacks an outer longitudinal layer''' or intracorporeal struts, '''ensuring a low-pressure structure during erections'''
