Textbooks off the top of a google search:
Gray’s Anatomy: The Anatomical Basis of the Clinical Practice (40th edition):
“At the penile neck it [Buck's fascia] blends with the fibrous covering of all three corpora.”
Herbert Srebnik: Concepts in Anatomy:
“Anteriorly, the deep perineal fascia becomes the (deep) fascia of the penis (Buck's fascia), which fuses distally with the tunica albuginea penis,…”
John Mulcahy: Male Sexual Function: A guide to Clinical Management:
“Buck's fascia is attached to the perineal membrane proximally; distally, it is tightly attached to the base of the glans penis at the coronal sulcus, where it fuses with the end of the corpora.”
Greg Maclennan: Hunman’s Atlas of UroSurgical Anatomy:
“At the distal end, Buck's fascia is firmly attached to the base of the glans at the coronal sulcus, where it fuses with the ends of the corpora.”
Ok, can’t argue with your sources. I did a search but the best description I could find did not include this information. I admit my only internet access is on my android and researching is kind of awkward but I will admit I was wrong about this.
That being said however on the topic at hand it still seems that at least the connective tissue between the CCs and the glans has been stretched significantly. I see no other explanation as to why his BPFSL would be almost a half inch longer than his BPEL and his glans soft to the touch when he is otherwise rock hard. If the CCs extended into the glans appropriately the glans should at least be fairly firm even if padded.
None of you seem to understand. I'm not locked in here with you.. YOU'RE LOCKED IN HERE WITH ME!
