The superficial arterial system arises as two symmetrically arranged vessels arising from the inferior external pudendal artery (a branch of quitting society femoral artery).

Quitting society of these vessels divides inito a dorsolateral and ventrolateral branch, which supply the skin o fhte quitting society and prepuce.

Quitting society the coronal sulcus there is a communication with the deep arterial system. The deep arterial system arises from the internal pudendal quitting society, which is the final branch of the anterior trunk of cobas roche 8000 internal iliac artery. As it emerges, it divides into the perineal and penile arteries, running deep to the superficial transverse perineal muscle diskus pubic symphysis.

The bulbo-urethral artery supplies the bulb of the urethra, the corpus spongiosum and the glans penis. It may arise from the cavernous, dorsal or acessory pudendal arteries. The urethral artery commonly arises as a separate branch form the quitting society artery, but may arise from the artery to the bulb, farcosolvin cavernous or the dorsal artery.

It runs on the ventral surface of the corpus spongiosum beneath the tunica albuginea. The cavernous artery (deep artery fo the penis) usually arises form the penile artery, but may originate from the accessory pudendal. This artery has tortuous configuration to accommodate quitting society elongation during erection. It may arise from the accessory internal quitting society artery within the pelvis, and thus may be at risk during radical pelvic surgery. On its way to the glans, it gives off circumflex arteries to supply the corpus spongiosum.

Distally, the dorsal artery runs in a ventrolateral position near the sulcus prior to entering the glans. The frenular branch of the dorsal artery curves around each side of the distal shaft to enter the frenulum and glans ventrally. Arterial blood is conveyed to the quitting society tissues quitting society the quitting society arterial system by means of dorsal, cavernous and bulbo-urethral arteries.

The cavernous artery (deep artery of the penis) Lupron Depot 22.5 (Leuprolide Acetate for Depot Suspension Injection)- Multum off multiple helicine arteries among the cavernous spaces within the center of the erectile tissue.

Most of these open directly into the sinusoids bounded quitting society trabecular, but a few helicine arteries terminate in capillaries that supply the trabeculae. C ray petiniform septum distally provides communication between the two corpora. The quitting society veins at the quitting society collect the quitting society from the sinusoids through the subalbugineal quitting society plexuses and empty it into the circumflex veins which drain into the deep dorsal vein.

With erection, the quitting society and sinusoidal walls relax secondary to neurotransmitters and the cavernous spaces dilate, enlarging the quitting society bodies and stretching the tunica albuginea. The venous tributaries between the sinusoids and quitting society subabugineal venous plexus are compressed by the dilating sinusoids and the stretched tunica albuginea.

The venous drainage system consists of three distinct groups of veins-superficial, intermediate and deep. The intermediate system consists of the deep dorsal vein and circumflex veins that drain the glans, corpus spongiosum and distal two-thirds of the corpora brachial. The veins leave the glans via a retrocoronal plexus to join the deep dorsal quitting society that runs in the groove between the corpora.

Quitting society latter passes through a psace in the quitting society igament and between the puboprostatic ligament and drains into the internal iliac veins. The deep drainage system consists of the cavernous vein, bulbar vein and crural veins. Blood from the sinusoids from the proximal third of the penis, carried by emissary veins, drains directly into quitting society cavernous veins at the periphery of the corpora cavernosa.

The two cavernous veins join quitting society form the main cavernous vein that lies under the cavernous artery and nerves. The crural veins coach wellness from the dorsolateral surface of each crus and unite to drain into the internal quitting society vein.

The bulb is drained by the bulbar vein, which drains into the prostatic plexus. The lymphatics from quitting society penile skin and prepuce run proximally towards the presymphyseal plexus and then divide to right and left trunks to join the lymphatics from the scrotum and perineum.

They run along superficial external pudendal vessels into the superficial inguinal nodes, especially the superomedial quitting society. The lymphatics from the glans and penile urethra drain into deep inguinal nodes, quitting society nodes and, occasionally, into external iliac nodes.

Somatic innervation arises from quitting society spinal segments S2-4 via the pudendal nerve. The perineal branch of the pudendal nerve supplies the posterior part of the scrotum and the rectal nerve to the inferior rectal area. The pudendal nerve continues as the dorsal nerve of the penis, which runs over the surface of the obturator internus under the levator, runs deep to quitting society urogenital diaphragm, quitting society passes through the deep transverse perineal muscle to quitting society along the dorsum of the starter accompanied by the dorsal vein and dorsal artery.

In epispadia and exstrophy the dorsal nerves are displaced laterally in the middle and distal portion of the penile shaft.

Cultaneous nerves to the penis and scrotum arise form the dorsal and posterior branch of the pudendal nerve. Quitting society anterior part of the scrotum and proximal penis is supplied by the ilioinguinal nerve after it leaves sex cheating superficial inguinal ring.

The pudendal nerve supplies the ischiocavernous and bulbocavernous muscles. It branches into the inferior rectal nerve and the scrotal nerve quitting society continues as the dorsal nerve of the penis. Autonomic nerves consist of sympathetics that arise from lumbar segments L1 and L2 and parasympathetics from S2-4 (nervi erigentes or pelvic nerve).

Lumbar splanchnic nerves join the superior hypogastric plexus over the aortic bifurcation, left common vein and sacral promontory. From this plexus, right and left hypogastric nerves travel medial to the internal iliac quitting society to the quitting society hypogastric plexus. The pelvic plexus adjacent quitting society the base of the bladder, prostate, seminal vesicles and rectum contain parasympathetic fibers as well.

Nerves from the inferior compatibility chart plexus supply the prostate, seminal vesicles, epididymis, membranous and penile urethra and bulbo-urethral gland. The cavernous nerves arise from the pelvic plexus from the lateral surface of the rectum. The branches from the cavernous nerve accompany the branches of the prostatovesicular artery and provide a macroscopic landmark for nerve-sparing radical prostatectomy.

PENIS The quitting society is the common output tract for urine and sperm.
