Bulb of penis
slight enlargement before each crus of the penis meets its fellow
The bulb of penis is the proximal/posterior bulged end of the (unpaired median) corpus spongiosum penis. Together with the two crura (one crus on each side of the bulb), it constitutes the root of the penis. It is covered by the bulbospongiosus.
Proximally/posteriorly, the bulb of penis extends towards the perineal body. The bulb exhibits a slight yet palpable midline notch upon its inferior aspect.
The male urethra enters the penis at the superior aspect of the anterior part of the bulb (most of the bulb is thus situated inferoposteriorly to the urethra), and the arteries of bulb of penis enter near the urethra.
The bulb of penis is supported by the erectile tissue of the corpus cavernosum.
Begin with the source’s own compact description: “Bulb of penis” is slight enlargement before each crus of the penis meets its fellow. The dossier treats that line as a proposition to test through Bulb, penis and slight, not as a finished interpretation.
Why this record matters
The phrase “slight enlargement before each crus of the penis meets its fellow” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Feb 23, 2026. The linked authority identifier is Q921517. None of the 0 selected statements returned an explicit reference.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
