"penile crura (paired) attach to the pubic arch. These join towards the symphyseal border and continue as the corpora cavernosa."
"the bulb of the penis is a median structure found between the crura and is attached to the perineal membrane. It narrows to continue as the corpus spongiosum. The urethra pierces its deep aspect to traverse the bulb as the bulbar urethra and continues to the corpus spongiosum."
"cylindrical in shape and expands distally to become the glans penis. The glans curves dorsally over the distal corpus cavernosum. The corona gland projects from the base of the glans and contain multiple preputial glands (as well as on the penile neck) which secrete sebaceous smegma."
"divide within the trabeculae of the corpus cavernosum to either end in capillary networks or branch into helicine arteries (most seen in the posterior region of the corpus cavernosum)."
"erection is caused by a rapid flow from the helicine arteries into the corpus cavernosum. This distension further contributes to the erection as the venous outflow is obstructed."
"distally folded to form the prepuce (foreskin) at the corona of the penis"
"the frenulum is a median fold of skin at the urethral aspect of the glans running between the orifice and the deep surface of the prepuce"
"the bulb of the penis is a median structure found between the crura and is attached to the perineal membrane. It narrows to continue as the corpus spongiosum. The urethra pierces its deep aspect to traverse the bulb as the bulbar urethra and continues to the corpus spongiosum."
