| crus penis | The posterior, tapering portion of the corpus cavernosum penis which diverges from its contralateral partner to be attached to the ischiopubic ramus. Synonym: crus penis, crus corporis cavernosi penis. (05 Mar 2000) |
| helicine arteries of the penis | The coiled terminal branches of the deep and dorsal arteries of the penis. Parasympathetic stimulation causes them to uncoil, allowing blood at arterial pressure to fill the cavernous tissue causing erection. Synonym: arteriae helicinae penis. (05 Mar 2000) |
| hemisphere of bulb of penis | One of the lateral halves of the bulb of the penis that are separated by a median groove on the posterior part of the undersurface. Synonym: hemispherium bulbi urethrae. (05 Mar 2000) |
| scapus penis | The free pendulous portion of the penis, consisting of shaft and glans penis. Synonym: corpus penis, scapus penis. (05 Mar 2000) |
| septum of glans penis | A fibrous partition extending through the glans penis from the lower surface of the tunica albuginea to the urethra. Synonym: septum glandis. (05 Mar 2000) |
| septum penis | The portion of the tunica albuginea incompletely separating the two corpora cavernosa of the penis. (05 Mar 2000) |
| spongy body of penis | The median column of erectile tissue located between and ventral to the two corpora cavernosa penis; posteriorly it expands into the bulbus penis and anteriorly it terminates as the enlarged glans penis; it is traversed by the urethra. Synonym: corpus cavernosum urethrae, spongy body of penis. Corpus spongiosum urethrae muliebris, the submucous coat of the female urethra, containing a venous network that insinuates itself between the muscular layers, giving to them an erectile nature. (05 Mar 2000) |
| neck of glans penis | A constriction behind the corona glandis of the penis. Synonym: collum glandis penis. (05 Mar 2000) |
| nervi cavernosi penis | Two nerves, major and minor, derived from the prostatic portion of the pelvic plexus supplying sympathetic and parasympathetic fibres to the helicine arteries and arteriorvenous anastomoses of the corpus cavernosum stimulating erection. Synonym: nervi cavernosi penis, cavernous plexus of penis. (05 Mar 2000) |
| superficial dorsal veins of penis | A pair of veins on the dorsum of the penis superficial to the fascia penis; they are tributaries of the external pudendal veins on each side. Synonym: venae dorsales penis superficiales. (05 Mar 2000) |
| superficial fascia of penis | A superficial layer continuous with fascia perinei superficialis. Synonym: fascia penis superficialis. (05 Mar 2000) |
| deep artery of penis | Origin, terminal branch (with dorsal artery of penis) of the internal pudendal artery; distribution, corpus cavernosum of the penis via capillary beds and via helcine arteries and arteriovenous anastomoses to produce erection. Synonym: arteria profunda penis. (05 Mar 2000) |
| deep dorsal vein of penis | A vein on the dorsum of the penis deep to the fascia of the penis; it is a tributary to the prostatic venous plexus. Synonym: vena dorsalis penis profunda. (05 Mar 2000) |
| deep fascia of penis | A deep layer which surrounds the three erectile bodies of the penis. Synonym: Buck's fascia, fascia penis profunda. (05 Mar 2000) |
